yes, I have two sumps running right now. On the 90 and 178 gallon....how often do I have to pat the dirt? With piranhas in the tank, I wouldn't want to constantly be patting the dirt. The grow to be 15" large and I have seven of them at 6-7" right now.
Will the black diamond sand / flurorite sand method be my best bet then?
