OK now I realize I have to get rid of the Bioballs in my trickle filter.Question is what to replace them with?? System consists of 54 corner bow tank with Maxireef trickle filter/heater and Remora c skimmer in sump part of the filter ,it is quite small due to limited space under stand.Do I replace bioballs with live rubblerock w or without substrate and raise water height/ Do I place substrate few inches and try to grow macro/w light/Do I leave empty and skim off detritis?In near future I want to make a refugium above tank so take this into consideration.Your help greatly appreciated in advance.Thank you!
