Ok so I have been wondering as to what a good flow rate is for internal filters for the following tanks:
a. 20 Gal Goldfish tank, 10 Goldfish inside
b. 15 Gal cichlid tank (7 yellow princes, all juvies <4 cm)
c. 15 Gal ABN pleco and shrimp tank, java moss
d. 20 Gal South American Cichlid tank, planted, el natural/dirt tank
There are several sources of information out there on the web and many of them are conflicting. Here is what I have found out so far and I would like your opinions on these.
a. 10-12x the volume of the tank
b. uncertain; values range from 6-8x the volume of tank to 10-12x the volume
c. none, filtration through sponge or corner filter suggested.
d. because it is a Walstad tank and planted, a rate of 4-5x the volume seems to be recommended, however lower flow rates do seem to work too...
