Eheim filter media options?

[Bill Stock]

I just got an Eheim 2026 for the plant tank to replace the AquaClear 500. I
want to use a spray bar and run a UV filter.

I've always kept a bag of Aragonite in the AC500 to keep my KH/PH stable as
I inject CO2 based on the PH. But I'm wondering about the best place to add
it to the Eheim. I guess the logical choice is to mix it in with the
BioMedia. Although I'm a little concerned about obstructing the water flow
too much.


Aside:

I haven't actually used the Eheim yet, but I think the quality is over hyped
based on my initial impression. The media options are far more restrictive
than the Fluval. I like the auto shutoff valves on the Fluval better. No
question the construction of the Eheim is moderately better, but at three
times the price of the Fluval I would hope so.I do like the settling chamber
idea on the Eheim, now if they had a back-flush valve for intermediate
cleaning. I guess the real disappointment is the manual (complete with
spelling errors), it looks like they ran the German version through Google
translator.

Are you have good luck with the aragonite? What size are the pieces?
I've tried this with dolomite, but the gravel was too fine resulting in
their becoming more of a mechanical & biological filter than a chemical
filter. Is there any chance of leaving them in the AC500? If you like
the idea of using canisters and not powerfilters, you can sometimes pick
up old canisters at fish club auctions. Even a Fluval 104 packed with
aragonite might serve the purpose, staying out of sight & mind, and not
messing with your 2026. It might even be a more reliable option to run
your UV, as UV typically works best under low flow (for optimal
sterilization), and should be installed in line with a system which will
not have too much variation in flow (ie: UGF powerhead). Your 2026 will
have some flow variation (it is doing your mechanical filtering), and
iirc, has quite a strong flow. Alternately, a coarse aragonite in a
canister might have very little flow variation or servicing requirements.
Just ideas.

Yes, it's hyped. On one hand, all these canister manufacturers are not
as good as we'd like, and on the other hand, they're all *much* better
than they used to be. If only we could pick & choose, Eheim's starter,
Fluval's valves, Emporer's intake screen, MaxiFlow's diatomaceous water
polishing, AquaClear's sponges, Pro60 bio-wheel output etc etc, and make
our own filter ;~).

I'm quite happy (beleive it or not) with the Aragonite. It seems to act more
quickly than the Dolomite I tried originally and is far less messy. The
pieces range in size from about 3/32" to about a 1/4". It's the CaribSea
barand.

I was considering it, but I already have three filters on this tank, two PHs
for the RUGF and the AC500. I actually wanted to get away from the AC500 to
reduce the current for the Cabomba. Maybe a smaller AquaClear just for the
Aragonite.

I actually bought the UV filter one size too big, to try and match it up
with the flow rate of the Eheim. Theoretically it should still kill
Parasites at the higher flow. Although it's primarily for Algae control.

Yep. Both Fluvals leaked today when I did their monthly cleaning. So if the
Eheim is more relaible, I'll stop bitching about the price/features
tradeoff. :)

Thanks Marco, I've read good things about Eheim's support. I've had one of
their pumps (1250) cooling my computer for years.

That's small, so there is some risk of it getting clogged up.
Interesting about the aragonite. I'm just going to use my dolomite as a
substrate now. thanks

lol on leak, I know what you mean. My Fluval 201 is piped into the tank
so I backwash it and never have to open it (maybe every 2 years or so).
Fortunately it is rock solid in regards to the impeller, but it was
surely one of Fluval's leakiest filters. As long as I don't open it, I'm
ok. Moving up to more modern filters, my 304 hasn't leaked (not the
original 304 model), and we used a lot of Fluvals around the store which
were also water tight. Although my 2213 is not new, it's never leaked,
except when a hose slipped off the filter. Regardless of manufacturer,
all these canisters should be periodically checked to make sure the hoses
are still tight. Just a characteristic of soft plastic hoses on hard
plastic fittings being subject to age & vibration. Have fun with the
2026.

I've used both Ehiem and Fluval canister filters, I would rate Ehiem as
being much better. The problem with the fluval canister filters is the water
can flow outside the baskets meaning the water is not filtered as well as
how the Ehiem's work.

Hello Bill,

may I ask why you replaced your AC 500? I have two AC 110s (same as 500)
and they seem to be doing a good job on my 220gal tank.

I like my AC500 fine. But I want to add UV and did not want another
PowerHead in the tank. Since I wanted to reduce the flow anyway, I decided
to go with a canister.

I've read this a few times, but I wonder how signicant this is. It would be
interesting to do a controlled test to see how both filters performed with
varying particle sizes, given the same flow rate.

$$ No you're not. I had a valve split after a few weeks and walked onto a
cold wet carpet one morning. Then the seal leaked and and had to be
replaced. Then one of the tabs snapped off that holds the top on. Then the
second (disconnect) valve got a hairline crack and leaked. This all within
a few months. What TRASH. I wouldn't buy another Fluval if I won the
lottery.

$$ The sponges in mine always were full of stuff from the water and I
believe it filtered the water really well. The workmanship and overall
quality of the product was a real disappointment. I'd rather stick to the
Aquaclears and Vortex Diatom filter (when needed).

For no-bypass systems (Eheim), I think the advantage is a higher
filtration efficiency (particle removal efficiency as a function of water
volume moved) but the disadvantage is there is a greater difference in
flow rates from empty to filled, and in a worst case condition, your
nitrifying bacteria could die off if the water flow was too low.
Generally requires a pump with higher head pressure to compensate for
this (push through the obstruction), and the impeller is (in theory)
designed to free-spin (spin without damage in the absence of waterflow).

By-pass systems (Fluval), conversely would have to move more water to
achieve the higher efficiency, but even if the filter is clogged, the
bypass ensures there is always a minimum water flow. Early Fluvals would
still have a nitrifying bacteria die-off (the bypass went around the
sponges), but the current Fluval's bypass keeps the bacteria in the main
sponges alive. Generally this requires a less fault tolerant (less
expensive) motor/impeller design, as there is less likely to be a
significant reduction in flow (which acts as a coolant to the motor).

With ideal maintenance: the Eheim is slightly better.
With normal maintenance: comparable imo
With poor maintenence: the Fluval is slightly better.

In other words, a dozen of one, or twelve of another ;~) ...but it's
still fun to watch the hype at work :o).

Any idea what percentage gets bypassed on the various Fluvals?

Nope, but it would be variable to the amount of back pressure caused by
the build-up in the filter stages.

Fluval redesigned their filters (more than once ;~). The 400 series
still had leaking problems when introduced, but this was corrected in a
re-design about 3 years ago. I sold many Fluvals and the quantity
returned because of leaks was zero. I also used them around the store,
and the quantity of leakers was zero. I'm satisfied now. Statistically
you will still be able to get defects, but at a rate comparable to other
canisters now.

Perhaps your information is a little dated, kind of like saying Hondas
are trash (which would be true looking at my (their) first Civic ;~).

Aquaclear are real workhorses, but I could write a lot about their
defects too. As for the Vortex Diatom filter, that would be a mercy
killing ;~). They sure could polish water, but what a PITA filter!

$$ I've read they've improved them. I think I'll stick with the HOB
filters. They're easier to clean than to disconnect a canister and clean
one of them, including their hoses..... bleah!

$$ This is true. My Fluval is pretty old.

Everybody is different, I've used both types "Fluval and Ehiem" and would
rate the Ehiem's as a better overall canister filter myself. But each to
there own..

What you need to keep in mind is, they work slightly different from each
other, without a doubt the Ehiem will give you more clear polished water and
do a better job than a Fluval canister filter overall. The Ehiem is designed
to filter all water that passes through it. Were the design of a Fluval
canister filter with it's baskets is designed to also let some water pass
around the baskets without getting filtered (probably to put less wear and
tear on the motor) to keep and even flow going without restiction.

But this means it will do a slightly worse job than the Ehiem.

Hagen does sell AquaClear parts through dealers, but the cost of a housing
would be the same as a new filter. Beware of the small plastic tab which is
pressed into the bottom of the filter to act as a spacer. On early smaller
models, this tab would fall off, and the filter would angle backwards
slightly. Ordinarily not a problem, except if the sponge rode up (from
clogging a bit), and now the water finds an easier path down the back of the
filter, emptying half the tank (until the waterline reached the intake).
Most of us here know that sinking feeling of hearing a splash when you walk
into a room ;~).

Absolutely, and we aren't even discussing all the other factors which make a
filter good or bad. In the 70s, I would have gone hungry standing on a
soapbox complaining about all the filter defects and crappy designs. Today
there is a lot less to complain about, making the differences between
manufacturers smaller and smaller. My personal favourite filters are not
Fluval or Eheim, but matt filters, but I put up with canisters for their
convenient (plug & play).

I've found the secret is not to take the Vortex apart, just backflush it
clean. Although mine has been sitting in the closet lately.

* Yep! I had that happen with a mini. :-) I have a clothes-pin behind
that filter to keep it level until someday I get off my lazy backside and
hot-glue something permanent to the thing.

Agreed, however what does a slightly worse job mean? If it means that
the water is not kept as clean, then you may be running too close to the
operating limits of the filter. It *will* mean that for equal flow
rates, one filter will clean faster than the other, but if the water is
already clean, the difference should only be apparent the first time you
use it, or every time you dirty the water up. Makes sense? Another
factor is that most filters (dependant on media, ie: closed or open cell
sponges) rely on biofilm to a certain extent, to cause particulates to
stick. This is why a brand new filter (any manufacturer) is generally
not the greatest, and only really starts polishing after the biofilm
develops. So much depends on your setup and the circumstances.

Once had a boss who wished that I wasn't so quick to stir things up from
the status quo, so I told him that I would try to stir gently. I think
his exact term was that I was a sh*t disturber ;~).
