Hi guys just need some advice/help with my 75 gallon tank to make it more clean and less maintainance, although my tank has already good filtration.. I just want to maximize the usage of my filtration. So anyone can give me advice? my filter is a 4ft Trickle Filter or also known as overhead sump... consist of 12 trays, 4 trays each row.. medias are bottom from top: siporax ceramic ring(bottom), biocubes(same usage as bioballs 3rd layer), 2nd layer is sera wool, 1st layer is wool with sponge. pump is rio2500... and i also have Seaquest 1600 on the other side just an extra pump to move the poo to the other side of the tank, any advice on how to maximize the usage of my filter?? just need some opinion.. thanks
