400 gph filter for 29 gallon?

[Gordo124]

Need a strong filter for my 29 gallon because the water is very nasty...
I was wanting to get the aqueon 55/75 for it, but im not sure if thats too much...
Wat is the max gallons per hour ?

You can't over filter but there can be too much flow.

There is no rule as it depends on what fish you have stocked. Small fish such as tetras and cories will likely not be able to handle such a rapid flow while large fish should be able to survive.

I run 1,850G/H for my 180G tank and you can definitely notice the flow but my fish seem fine.

In short I think that anything over 10 times your tank volume is probably pushing it unless you have large fish or fish that prefer fast water movement.

Can you post some pics of your 180 tank , cynic?
