Need recommendation for filter

[krabbie]

I intend to have a chiller for my 422 tank, is Eheim 2028 powerful enough?

Eheim 2028 is a filter...

[illumnae]

i think he meant whether the Eheim 2028 was sufficient to power the chiller and provide adequate filtration/flow for his 422 at the same time.

i don't think it will be krabbie. i'm using a 2028 for my 422 connected inline with an external reactor, and i find that i'm not getting enough flow and added an extra powerhead in the tank to increase the flow. i'm thinking 2x 2026 or an eheim pro 3 may be better

I'd suggest the 2028 to power the chiller and another powerhead, or slightly less powered canister to power a CO2 reactor and to provide flow.

[krabbie]

so eheim pro 3 is sufficient? I don't think I want to have 2 filters ... too many equipment in the cabinet (2xfilter, 1xchiller, fertilizers, etc) ... If I go for the powerhead, what power shd I choose? Is it better to connect the powerhead to the chiller instead?

Actually, I think 2028 is enough..Get atman filter..I think they have 1 that is 1350l/h. I think it should be enough. Or custom make a filter..Like what i did. I think Vinz also have a custom make filter...

Heh I'm selling that Atman CF-1000 filter. 1350L/hr. Anyone want?

Wow ... just went to check out the prices for Ehiem filters ... damn expensive man ... i didn't know that prices have increased by so much ... Ehiem Professional III is **almost** double the price of 2028 (considering that 2028 is already higher price that I know)

The guy told me 2028 is good enuff for 422 with chiller ... I wonder if I can trust him.

Chillers are designed to work with recommended flowrates.

If your flowrate is too low, then you will probably find your chiller switching on and off in every few minutes. If it's too high, you might find it running for very long periods. Both situations will lead to inefficient usage, much bigger electrical bills, and probably shorter chiller life-span.

1. Decide which chiller you want. Don't stinge too much here. Get a good one and re-coup your cost thru lower bills, less heat in the house, less noise and less family disapproval. Note the recommended flow rate.
2. Get a filter to match the flowrate. Upsize the flow rate because media clogging and inline equipment (CO2 reactor, chiller) will slow down the flow.
3. Get proper size piping. I've seen people running filters that require big hoses, then downsize the hose to fit the CO2 reactor. The reduce diameter slows down flowrates.

To get the optimum out of your chiller, make sure you run with the correct flowrate... aim for the upper range of the recommended flowrate. That way, even if your flowrate slows down, you are most likely still in the recommended range.

If the flowrate is too high entering the tank, just split the output or tap to a very long rain bar. It's better for circulation too.

A large part of the LFS industry still suffers from 'can one lah' mentality.

Oh by the way, no need to aim for really low temperatures. In my honest opinion, 27 degrees celcius is a nice balance between plant needs, budget and home 'heating' requirements.
