I have a 29g tank with a 10g sump that will be home to 5 African cichlids, how many gph do I need to turnover? Also, the total line from sump to main tank is around 7', what size of pump do I need.
with a wet/dry (trickle filter), I usually only bother with 3x the tank volume per hour. A lot of people disagree with me, but I have several tanks with a high bio load that the filter keeps their nitrite/ammonia at 0. That's proof enough for me.
