Ozone or UV Sterilizer Question

[Microbot]

I have read on a website that UV Sterilizers can reduce unwanted Algae, is
this true and if so, then how effective is this against the Algae?
Also, I was told a while back by a LFS that Ozone kits are effective for
reducing and/or removing Algae problems, once again, is this true and how
effective is this method against Algae problems?
Last question is that if both can do this, then which one of these methods
would be the best and safest method to use??

I have a Green Hair Algae problem in my tank that is driving me insane, I
dont have filtered fresh water to add yet so it is straight from the tap,
Yes i know that a water filter will no doubt be my best answer but at Filter
prices here in Australia, it isn't on my shopping list just yet, UV and
Ozone are way cheaper options and if they can assist me battling this Algae
untill I can afford a good Water Filter then that's ok to me.
Any help is muchly appreciated.

Thanks in advance
Microbot

Would you consider buying and using distilled water from the
supermarket instead? Your tap water is surely adding
nitrates and phosphates to your tank, and this will
continuously feed and fuel the GHA in your tank. Did you
already read this article?

I've not used a sterilizer because it will kill good
bacteria along with the bad bacteria.

I've not used ozone, but if you do be sure to read up on how
to keep using it safely.

Yes thanks Marc, I have read your articles and would gladly buy distilled
water if it was cheap enough.
I saw in a thread once that where you guys are it is a rather cheap option,
but here in Australia where i am, I cant find it anywhere close to as cheap.
Just the price alone of the container that holds the water is not cheap
here.
My nitrites are so low they barely register on my test kit.
My Phosphate detects nothing on both the tanks water and my Tap water.
Lighting time is at present 6 hours, Algae seems to grow even if the lights
are off..
I dont mix my water, I use natural seawater..

Use plastic fuel containers. New of course, old detergent 60 gallon
drums and cooking oil containers are nice as well as garbage cans.

I HAVE been using natural seawater since i started the Tank, Not exactly
sure the date I started it but has to be in its mid second year by now..
Top offs are done with Tap water which the test kits tell me have non
detectable levels of phosphates, Nitrates, Copper, Ammonia and everything
else that is bad.
I have been using a Protein Skimmer since the start.
I only started getting this dreaded weed algae since i bought some Base Rock
to add to what i already had, this rock had the algae already on it and i
was told it would just die off, I have since realised that this was not very
helpful information and it did not die off but instead has taken over the
Tank.
I keep manually removing the stuff (which takes ages) only to have it back
just as bad as it was before within weeks..

I have one Aquaclear 500 hangon filter and a Canister filter.
Also Live rock which i have half filled the 4 foot tank it is in, sorry no
idea how much in weight.
A Hangon Overflow box to a 3 foot sump used only at present to add to the
waters capacity. Nothing in it except for some Mud and Crushed Coral (which
both have only just recently been introduced).

Finding a container is not a problem, it is finding a source of the water to
put in the container!
Purified water just is NOT cheap here, Just water purifiers for your home
taps that you can buy at hardware stores can start at around $399.

It seams to me that you don't have the problem in the water from tap or
ocean. It is your filtration technique that's causing nitrate problems.
Using canister filters, hangon filters with sponge in it is in fact nitrate
factory. Crushed coral in your sump adds nothing to filtration but produces
nitrates. Your best way would be to use only live rock and protein skimmer
for filtration, combined with regular water changes. Be sure to provide
enough water flow in aquarium with minimum of 10 times the volume of
aquarium per hour.
Since you live near the source of NSW you coul find yourself nice pieces of
live rock and replace those rocks that are overgrown by algae.
If you want there's nothing wrong in using ozone but you must be very
carefoul with it. It must not reach main tank or it can kill its
inhabitants.

What does a gallon of distilled water cost at the
supermarket? Here is runs about .50 a gallon, maybe .10
less or .20 more depending on the store.

Do you have snails in the tank to help eat the algae that
you can't pick off?

I use ocean water also.
I do use a small amount of RO/DI, but with enough fresh ocean water
you can practically forget about it....I was listing what I use to
haul mine from the sea.
I got a great RO/DI filter from Canada for $100 US. How is shipping
to AU?

[Microbot]

Thanks for your reply.
I had no problem with the Algae until I added the rock that had it growing
on it already, since then it has grown out of control.

If i did a test for NitrAtes wouldn't this show up on the test if i had a
NitrAte problem?
I have even tested for NitrAtes by taking the water sample directly from the
sponge in the Hangon Filter and from inside the Canister Filter, All tests
show NitrAtes are very low. (LESS than the first colour on the Test kit).
Waterflow is good.
Rocks nearby to here are not quite Live Rock quality and I really dont want
to throw the Rocks i have already away and start anew...
The crushed coral is in the sump under a few inches of local mud picked up
from nearby to here.
This is an experiment started by a friend in here..
Filtered water, Ozone and UV are the only things i can think of left to try
to solve this weed issue..

I have never heard of anyone anywhere close to hear where i am in Australia
(Queensland) selling distilled water or any kind of water in anything larger
than 1-2 litres drinking water bottles... And at the cost they sell that
water for, it is not an option.
Small drinking bottle (mineral water they call it) around $2.50 AU which is
somewhere near $4.50 US...per small bottle (600ml).

I do have some snails in the tank, I used to have many snails but i have
notices that since the weed took over, alot of the snails abd Hermits have
seemed to have disapeared...
Alot of empty shells laying around now, though there are many NEW tiny red
shelled Snails in the tank. very small and almost translucent.

Shipping is pretty expensive shipping them over here from what i remember.
We looked into buying one from in the US and shipping it here but from
memory shipping nearly doubles the cost..
We did find a place in AUS that has them and the prices are not too bad, but
the wallet refuses to let go of the cash just yet. hehe
Have a few other bills etc to get out of the way first, which is why i was
asking about Ozone and UV efficiency against the weed.

Looks like I'll have to get a Water Filter....
I'll also remove the Canister Filter and Hangon Filter just in case it IS
feeding the problem..

I only can assume those algae are taking in those nitrate.
As Mislav stated are the method I normally recommend. PS need to very
efficient and must have good water circulation to combat algae. Your PS
should really smell if it efficient enough. Your inhitant like Tang / crab
and or shrimp should be munching on those algae. Try feeding less to your
critter so they get hungry enough to turn to grazing. The large algae may
need to get prune and siphon out at the same time so it will not spread.
Small algae should be taking care by those janitoral crew and or your
grazing critter.

[Microbot]

Thanks,

I do have very good water circulation and the skimmer is working just fine,
it produces some really foul, dark water which i clean out regularly.
I cant imagine feeding my tanks critters any less than i do now, I dont
directly feed the inverts and only give enough food for the fish to eat in a
few seconds.
Nothing is really left to settle on the bottom.
The critters i have seem to feed constantly on the rocks, eating the weed
but it grows faster than they eat it.
I prune the algae out often and yes i siphon the water near and around it
as i pull it from the tank, I have done this more than i care to remember.
The stuff grows on EVERYTHING, I'm sure if i left my finger in there long
enough then it would grow on it too.
As i said, NitrAtes are showing as not being a problem, but the only thing i
have not tried is to remove the Canister filter and Hangon filter i have on
the Tank.
If removing them doesnt solve the problem and Filtered Water doesnt then i
am at a total loss..

Cheers

You don't need to remove canister and hang on. They are good for
circulation. Just remove the media from them. If you remove whole media all
at once it can lead to amonia and nitrite rise because you removed oxidizing
bacteria and new bacteria didn't have enough time to colonize in numbers
needed for amonia and nitrite reduction. Remove it slowly over, say two
weeks. You can also put some good qualitiy activated carbon inside of
canister.
The fact nitrates are low is because of algae growing in your tank. They are
depleeting nitrate so you can't read it on your test but that doesn't mean
that your aquarim is not producing too much nitrate.
I'm also suspicious of mud. It also can produce nitrates. Especialy if it is
not something already tested in aquarium. You should let your friend to
experiment in his tank not yours.
It is common now among SPS keepers to run barebottom tanks to avoid buildup
of detritus that leads to nitrate problems. If you don't watn to have
barebotom then I suggest regular sifoning of crushed coral.
Ozone can help but it isn't mirracle. If you don't do other things right it
won't do much.

My only suggestion at this time would be.... continue siphon while you pull
those large algae out like a vacuum cleaner. Do not let it spread awhile you
pruning.

Remove your media from your conister slowly.
Make sure you have good strong ciculation flow to your PS / SUMP etc.
Continue to prune / pull algae.
Less feeding. Your algae should be a food source for your critter.\

Perhaps someone found this to be true. I have two 8 watt U/V sterilizers, one on
each of my Fluval cannisters. I also have an infestation of hair algae that is
completely out of hand. It's responding a bit to the 50 hermit crabs I just
added, but I think they need some more help.

IME, U/V does nothing to control algae.

Thanks, I think i'll be giving the UV a skip for now..

Hi George,
It seems to me you have the same problem as Microbot,
you are both producing large amounts of nutrients (mainly nitrate) in
your canister filters etc. which is encouraging and fuelling the algae
growth, not measurable because the algae is consuming it as fast as
your producing it. Your filtration should consist only of live rock (
about 1.5 to 2lbs per gall of tank capacity, much more than 2lbs will
be counter productive ), the live rock needs to be reasonable size
pieces, ( the bigger the better) small pieces will not generate an
anaerobic area, a DBS, plenty of main tank flow ( 10 tanks per hour
bare minimum, I use 20 or more ) plus a good protein skimmer. This will
take care of your nutrient problem which in turn will take care of the
algae problem, but not over night !! you need plenty of patience with a
marine tank. You could help things along with plenty of nitrate,
phosphate and silicate FREE water changes until you start to see a
reduction in the algae.
regards,
unclenorm.

No, my problem seems to be a relatively high level of phosphates in the tap
water. RO is not an option in my situation, and DI runs about $2/gallon around
here.

[Microbot]

Around $3-4 per 4 litres around here..
Thats $4 AU not US...AU is nearly twice US costs..

EBAY you can get a RO 110 gal hour unit for about 80 bucks ,I have one and
Love it!!

They are sold by Filters Direct and made by Water General. I have both the
85gpd and 110gpd systems. Although they state its a 110gpd unit its actually
a 100gpd membrane. Their is also a seller Aqua Safe that sells some good
units for same price.

Here's a link to the seller of them.

Thanks. I misread the original post and thought he meant a unit that would
produce 100 gallons per hour.
