Best Filter

[bachamp]

Well what is the best filter money can buy.

That is what is the ultimate filter one can make, buy, steal?

[Chrona]

Depends on what application (salt/freshwater, tank size, fish type, etc)

Eheim has my vote though.

[bachamp]

Fresh water, large tank 70+ gallon

What Eheim filter?

or maybe even

if your fish can take the current

If you got a massive filter with a high flow rate for a small tank, (e.g filter flow rate 1000 L/h, tank size 100 L). Would you have problems with to much current?

If so could you seperate the tank with a piece of perpex that went the full length of the tank with lots of little holes in it that would slow the water movement down by spreading the suction out accross the length of the tank?

Also is there some things that you cannot filter?

It is possible to have a filter that means you only have to change the water 3-4 times a year.

Yes that would be too much current for a freshwater tank. Turnover rates do not scale up, so while you can do 100gph in a 10g tank, you cannot do 550 gph in a 55g tank without A LOT of tubing and outlets. Even then, too much water is moving.

No, filters break down ammonia into nitrites then into nitrates. You need to remove the nitrates via water changes. There are certain devices that remove nitrates, as well as live plants, but they don't replace water changes because it also brings in trace elements. Regular water changes in a freshwater tank is a crucial part of a healthy aquarium. I do 50% weekly.

I'm running an AC110 on my 29g tank. It produces about 500g/h water flow and there is quite a bit of current on the surface, but the fish love it. They'll play in the current for a bit, then go down to the bottom to rest and chase each other, they it's back into the current for another work out. It's like a hamster wheel for fish ... :hmm3grin2orange:

I'll echo the Eheim canisters. I use the Professional II models, 2026 and 2028 on my larger tanks. Dead silent, never a problem, easy to work on. Do a search online and you will see many users agree that they are great filters.

Eheim 2215!! couldn't believe it was running until I put my hand on the side.... great filters..

[gm72]

The 2215 is the thermofilter version, right?

[blue fin]

don't know what you mean by thermo version... it is a canister filter, does not have a heating element of any sort, very efficient filter, just have to make sure you don't kink the hoses.

[cocoa_pleco]

fluval canisters are good

[Chrona]

2213, 2215, 2217 are the Eheim Classics

2028 and 2026 are Eheim Professional II's

2126 and 2128 are heated versions of the Eheim Professional II's

[cocoa_pleco]

my hydor had a outer heater. It connected on the output tube and heated the water.

Eheims are good too
