to much flow?

[jake m]

is a 3400gph pump to much for a 180 gallon? it will be for a diy canister filter. completely hooked up it will prob have about 1600-1800 gph.

hello?

If you have a drain as long as its draining fast enough and they fish you are keeping in it don't mind the flow then the more you have the better as long as everything is comfortable with the flow the more the better imo

 

[jake m]

ok, I just didn't want to turn the thing into a giant underwater hurricane. any ells have some input or experience with this?

10x turnover is ideal, certainly not excess for most fish. Some like more and some like less but 1800gph in a 180 wont bother many fish

 

[jake m]

I mite be wrong but isn't it 10X flow before adding in all the restrictions?

 

[brich999]

You said a 3400gph pump running about half that after restrictions and such. On a 180g tank 1800gph would be 10x turnover. Thats always what I aim for for turnover

If your aim it in a smart way then the 3400gph pump isnt too strong. A long enough spray bar with enough holes would evenly distribute it around the tank without causing any discomfort to the fish.

It really depends upon the type of fish.
Rheophilic fish need very heavy flow, with an ATF or cichlids like Tomocichla or Theraps, it would be hard to ever produce too much flow.
For discus or certain other oxbow, or swamp fish, it may be too much.
In some cenotes containing Jack dempseys, uropthalmus and live bearers where I have snorkeled, I have had to hold on to mangrove roots to keep from being swept toward the sea.

it will be heavily planted and have tetras in it.
