I have noticed an increase in questions about nitrate. I have a fish only 120 gallon tank with a sand bed about 2 inches. I have a bak pak 2 and a wet dry sump made out of a 20 gallon high tank. I am running the water through floss and enough bio balls rated for 120 gallons. More and more threads are popping up about putting live rock in trhe sump, under water of course. My question is how much live rock and should I run bio balls with it? My inhabitants are a 3 inch porcupine, a 12 inch snowflake eel, a 5 inch lunare wrasse, 4 small blue damsels, and a 2 inch maroon clown. I have about 100 pounds of live rock right now but am about to possibly double that amount. I haven't been using ro water. Any suggestions would help.
