i have read that bio balls are nothing but nitrate factories and it seems that everyboby doesnt use them so im thinking of removing them from my system. is there anything i should replace it with? i have the aga model 4 wetdry, asm g3 skimmer, 18 watt uv, 120gal tank with 120 lbs of lr and is a fowlr tank. i was thinking of replacing the bio balls with rubble lr but that means that the lr wont be submerge in water, just water trickling on top of it and there will prob be dead spots all over it, was wondering if this was alright or is there anything else i should do? a refugium wont work b/c i dont have the room for it.
thx in advance
