Exclamation How much circulation is too much?

Hello,

I have a planted tank at 180L which works out to be 48 US Gallons.

Currently I have an Eheim Professional 3e 350 Filter working its magic to filter the water as well as two powerheads / circulation pumps- one is the Fluval Sea CP2 (which does 1600lph) and the other is Hydor Koralia Nano 1600 (which does 1600lph).

Therefore, from the powerheads alone, that is 3200lph plus whatever the filter is achieving on it's moderate setting.

Is this overkill?

Should I remove one of the powerheads? Or is a stronger current better?

The tank currently is heavily planted with CO2 injection. Fauna I have in the tank are a dozen Neon Tetras; two Corydoras agassizii and around a dozen Otocinclus affinis.

Thanks,
Dan

P.S. Not sure which section to place this thread in!

How's the tank doing? It's probably hard to overkill flow, but personally unless you like the look of extra equipment like powerheads I think you can remove them. The filter you have should be more than enough.

I agree, don't like running extra equipment unless I need to...more flow will help distribute nutrients/CO2 better but unless you have noticeable dead spots it might not be necessary. In terms of too much flow, I'd monitor the fish and see if you notice them struggling....but probably easier said than done.
