I have a 140l,30 gal freshwater tank.Can someone tell me what turnover I should have from an external filter?

Question

It is a 3ft tank and we want to buy an external filter but I don't know how many times it should turn the water over in an hour?

Answer 1

Gallons x 10 I would recommend a penguin 330 or emperor 400

30x10=300 so at least that.

Answer 2

8 to 10 times an hour is the reccommended turnover rate.  So you should get a filter that has a gph (gallons per hour) rate of at least 300gph.

Personally, I would go for one of the Marineland filters that has a 400 plus gph.  In this case, more is better.

Answer 3

anywhere from 5x to 10x depending what kind of stuff is in it

5x per hour is a good minimum

Answer 4

The turn over has to be automatic, you dont have to worry about that.
