I have a 75G fish only sal****er tank that if I had to guess has about
30 pound of live rock. Right now its on a really light bio-load with
two Marineland filters: Emperor 400 and a canister 350. What size and
brand/type of UV sterlizer should I get? I was thinking of a unit to
hang off the back of the tank with its own pump or run the return half
of the water from the 350 that goes out the nozzle and not the
bio-wheels through it. I'm thinking that 25 watts is a fair size to use
with a flow rate in the high 200s to mid 300s GPH...

Thanks,
Jeff

I think you should pass on the UV if you don't have a protein skimmer.
Do you have one ?

Any "fish only" tank with live rock and small bio-load should be
treated as far as filtration goes as a reef tank. This means that
the majority of water filtration should be done in the live rock...
You can use mechanical filters like you have mentioned but
you need to treat them as mechanical filters only, and do not let
them build up organic gunk there because this turns into a nitrates
factory... Any such filter should be cleaned several times a week
to remove all organic waste caught in the filter...

Processing of ammonia and nitrites will be done in the live rock.
To help with the amount of organic compounds dissolved in water
befoer they need to be break out to nitrates in the live rock you
can use skimmer. Skimmer removes proteins from water BEFORE
bacteria gets to them and converts them into phosphates/nitrates.

Also, opinions about using UV sterilizers in aquariums are divided
and my opinion is: it is not needed. Fish are pretty hardy when
taken good care for, well fed and not stressed and they can
defend themselves from many diseases making UV useless.
Even if you do not have corals and strong lights try to benefit
from "reef-like" enviroment in your tank: a lot of live rock will
host a large population of beneficial worms, snails, crustaceans
which in turn help managing waste created by fish, like in the ocean.
UV lamp in a natural aproach to a reef tank is simply a waste of money.

This is an advice from the reef tank owner point of view...
If you want to know more from a fish-only setup owners perspective
you might want to visit another newsgroup dedicated to
non-reef setups: news:rec.aquaria.marine.misc

Good luck!

I beleive UVs are an essential part of Marine fish and Reef keeping, in
fact in our service route, we will not accept a contract for marine
maintenance without a UV sterilizer. The above points are ALL valid,
but you have to remember that an aquarium is not or will not be the
ocean. IT IS a closed system. Via Aqua makes a skimmer/ UV combination
that is excellent for your size aquarium. Also contact time is
important, not wattage. I have been building a custom 15 watt UV for
years (that my customers swear by) that will work well with a Magnum or
as a hang on the back application. One point is, unless you have CLEAN
metal halide lights, with nothing between them and your water, you are
not duplicating the ocean.
I have a blog about UV sterilizers that go into depth about how and why
they work.

And why do we need UV sterilizer ?
Why would I want to *sterilize* my water in the tank ?

I want the water in my system to be as live as possible!
I am NOT interested in killing planktonic animals or algae
in the water column. Opposit is true: I want to encourage
the growth of planktonic life forms in my tank because they
become food items for corals, fish, filter-feeding invertebrates
like sponges, feather dusters, clams, sea cucumbers, etc.

One point is, unless you have CLEAN metal halide lights, with nothing
between them and your water, you are not duplicating the ocean.

There are thousands of reef tanks out there without UV sterilizers.
They are doing perfectly fine... Why would they need one ?

I have a blog about UV sterilizers that go into depth about
how and why they work.

The question is "why do you want to make your reef tank water dead?"

Prpoerly managed, a UV sterilizer does not render a marine tank
sterile. A timer is often used, also most of these life forms are not
passed thru the sterilizer in a healty aquarium. Again. a metal halide
also performs some sterilization, and is considered neccesary by many
to duplicate the ocean as close as possible.

Good point, you can have a sucessful reef aquarium without one
(although I question the outcome of a fish aquarium), but the
sterilizer helps improve the odds of a new reef tank in particular. As
the reef aquarium ages, the time the sterilizer is on is less.

How can you prevent "these life forms" passing through your sterilizer?

How can UV sterilizer work in a selective way killing only disease
causing inverts/bacteria and not kill beneficial ones?

How can you justify UV sterilizer on a timer, and then expect it will
have any role in disease prevention ?

This is the first time over so many years in this hobby I hear from you
that people use metal halide lamps to sterilize water in their tanks,
to duplicate the ocean...

Are you 100% sure you know what are you talking about?

Can you quote *anybody* recomending the usage of metal halide
lamps without UV protection filters in marine aquaria? I do not
know any person doing this. All metal halide lamps used over the
marine tanks HAVE UV PROTECTION to block harmfull radiation
type "C" allowing only bands "A" and limited "B" to pass through.
Corals and any other life forms using UV light are tuned to
bands "A" na "B", not to the germicidal band "C". Band "C"
is *very harmfull* and that is why it is used to sterilize water used
in medical purpose or bilogical labs, medical rooms, etc.
That is why UV sterilizers have the bulb enclosed in the not transparent
case - otherwise it would make more harm than good to your own eyes,
skin, plants in the room. The Planet Earth also has UV filter in the
upper atmosphere - you have probably heard of the ozon layer -
this is our protection against killer effects of UV band C radiation.
Yes, most of band A and limited band B UV rays are reaching
the surface of the Earth and travel through water, but it is not band C!

There are thousands of reef tanks out there without UV sterilizers.
They are doing perfectly fine... Why would they need one ?

Good point, you can have a sucessful reef aquarium without one

Than why do you force your clients to use UV sterilizers ?

(although I question the outcome of a fish aquarium), but the
sterilizer helps improve the odds of a new reef tank in particular.
As the reef aquarium ages, the time the sterilizer is on is less.

Why do you have it at all ? This is not selective device, when it
is on it kills almost ALL LIFE FORMS PASSING THROUGH it
without checking if the animal or algae is beneficial or not...
It is simply not needed especially in a fresh tank, where there
are limited amounts of planktonic forms and you are more
interested in encouraging their growth than in a mature tank
where planktonic organisms are well established already...

If you keep an artificial, sterile fish tank with dead rock and fish only,
than you can use UV sterilizer - if you really believe it helps.
You do not have proper algae nutrition export in place in such
tank so high nitrates and phosphates could cause green water
outbreaks, and then UV lamp can be doing some good...
You would be doing better than you convert such tank to FOWLR.

But in a natural aproach to a FOWLR/REEF tanks, the UV lamp
is simply unnecessary cost you simply waste your money on.

It doesn't sound like buff82...has a protein skimmer
which IS undoubtedly a heck of a lot more important than UV.

Not to mention the fact that canister filters are not meant for marine type

mechanical and biological filtration to cope with
ammonia and nitrites, shortly called nitrification.
Power filters (HOB or canister) are used for this...

I've kept U/V sterilizers on my tank since 1976. In my experience, they will
slow the rate of parasitical infection, such as ick, but that's about all you
should expect out of one. No matter how you set one up, there will be "dead"
spots in the tank, and the water will never be really sterilized. I'm not sure
it would be a good idea to do so anyway.

Anyway, 25 watts is really heavy artillery for a 75 gallon. I have a 125 gallon
with an 8 watt sterilizer on it. I would be more comfortable with two of them. I
think you wouldn't need more than a 15 watt unit.

Whatever you buy, avoid the "Angstrom" brand. This used to be made by Hawaiian
Marine (and may still be). They make a unit that hangs on the back of the tank.
The plastic housing will corrode and begin to leak within a few years. I've had
two of these units go bad like that; one after about 15 years, but one after
only two. This is what I had - http://tinylink.com/?LDm1aDtXkJ

One thing to check for is the ease with which the bulbs can be changed. They
should be changed about every 6 months. Try to find one where you can change the
bulb without completely disassembling the unit.

It also adds in oxidizing organic substances, although not as well as ozone and some use
UV for that very purpose, especially if the are worried about ozone potentials hazards.

Enveloped MH are pretty much protected from UV, at least excessive UV, by the
borosilicate envelope bulb ( non- DE). I might add some or many coral can use MH UV.

But it would also help out with the cyanobacteria would it not after I

you can do a really good job w/out lossing water to a bunch of buckets.

Jeff,
your cyano outbreak means simply your system is OUT OF BALANCE.

Even if the UV Lamp will deal with the symptom, it will not cure
the cause of the problem. The cause of the outbreak is lack of proper
nutrients export.

Remember, in a fish tank, as in any other closed system, what you
put there, stays there, untill you remove it...

You put fish food there and it will accumulate in a form of nitrates
and phosphates until it reaches the alarming levels and tank will crash
due to the cyano outbreak or massive green hair algae infestation.
Correctly designed system has proper ways for nutrients export.

Only one of many methods is the partial water change you mentioned.
Others include skimming, growing algae in a separate container

Yeah but I think my problem is phosphates in my tap water that I use to
top-off/water change. I have not tested it...maybe a RO unit would be
the way to go but the fish seem fine with the cyano just as long as I
keep it from covering the live rock. If the phospahtes don't bother the
fish and UV would do the trick I was thinking that would be a more
pratical way to go. I don't get enough rain here to collect and using
bottled water would be very expensive. Isn't there a product you can
put in your sump that absorbs phosphates? Is it any good?

Jeff,
your cyano outbreak means simply your system is OUT OF BALANCE.

Even if the UV Lamp will deal with the symptom, it will not cure
the cause of the problem. The cause of the outbreak is lack of proper
nutrients export.

Remember, in a fish tank, as in any other closed system, what you
put there, stays there, untill you remove it...

You put fish food there and it will accumulate in a form of nitrates
and phosphates until it reaches the alarming levels and tank will crash
due to the cyano outbreak or massive green hair algae infestation.
Correctly designed system has proper ways for nutrients export.

Only one of many methods is the partial water change you mentioned.
Others include skimming, growing algae in a separate container
(algae scrubber), keeping a population of grazers in your tank
(snails, urchins, tangs etc) which acumulate these nutrients and
build their bodies out of them removing them from water column.

Yes, there are phosphate sponges. You can remove phosphate from
the water this way and the cyano will die. Died cyano release their
accumulated phosphates and the water will be nutrients rich again...
So you need to be carefull using these chemicals and measuring phosphates.

Cyanobacteria can absorb nitrogen in free form so they do not need
nitrates. All they need is phosphate rich water...
All green algae you might see requires nitrogen to build chlorophyl.

You are drifting away from the "reef" topic this group is dedicated to...
Maybe you should visit news:rec.aquaria.marine.misc and ask experts
keeping FO and FOWLR setups how do they manage to keep their
systems stable. I have always worked with reef setups so I do not
feel competent to help you with your FO system.

That is Why uvc is sheilded in a unit, but you also do not want stare
at uvb lamps either. I wrote a blog based on my experience about uv
radiation, it gives the different wave lengths required for germacidal
sterilization. UVC lamps work best at the upper end of the uvc spectrum
(265 NM).
Anyway, back to the original subject; I would recommend a RO unit for
buff82driver, and to take all the advice given here and utilize it for
his application. Also the Skimmer is a puchase I would recommend. If
you do go with a UV also, a 5 to 15 watt unit is all you need.

This product, again, deals with the symptom, not the cause.
Until you fix your cause for high phosphates, cyano will return
no matter what you do to kill you every time. It is in the air,
in the food, in the animals you bring from the store etc...

I will add (again) using an RO unit will reduce the phosphates added
to your aquarium from water changes, but also proper lighting is also
important in prevention. I should have added when I looked up this
product, that I have only used it a couple of times, as I agree that
prevention is important thru proper water management. I rarely have had
outbreaks of cyano by keeping a balanced and well lighted aquarium.

Thanks for all the advice. I think I'll go with sponges to remove the
phosphates instead of a RO unit. I have not priced them but I bet it
would take a lot of sponges to equal the cost of RO set-up. My lighting
is nowhere near reef keeping standards but I just have fish. Thanks
again for the advice.

You can buy a decent RO unit for the price of ~$100.
Phosphate sponges unfortunatelly release some amounts of
aluminium or iron to the water - probably not a big issue in your
tank, since you do not have corals, but still...
RO unit will remove almost total phosphates from tap water
without releasing anything harmfull to the water...
It does not remove phosphates which were created by fish
activity in the tank itself.

"Safe"

I guess that all depend on ones point of view PZ. Depth does play a roll and the actual UV
output. There have been a few articles on UV and its effects. Most will recommend that
one gets a protective UV shield or check on the one that came with the unit, if there
seems to be a UV problem.. Some of the plates, glass or plastic with DE bulbs, are really
not protective and act just a splash guards or light diffusers, which does not mean UV
protection in all cases. Some (reefers )use such lamps with no plate at all. I don not
have any names right of hand.

These are not good products for reef tank as they are activated alumina, which releases
Aluminum which is toxic and effects some corals. If one is looking for a phos remover you
are better off with ferric oxide hydroxides, which is better, more effective and has no
