I have a Deep Blue wet/dry sump (very similar to the Eshopps wd-300) on my 90 gallon African Cichlid tank. The drip tray it comes with has 3/8" holes which I cover with a piece of filter floss, and underneath it I have some Poret foam, then bio balls, and then submerged some bio home media. I find that the water trickling down over the bio balls is just concentrated in a few streams and there seems to be lots of dry spots on the balls. Does anyone have tips on how to better diffuse the water evenly over all the bio balls? Maybe a different type of drip tray, or more smaller holes?
