I have a 29 gallon plenty of LR and LS and PS its been runing for about 4 months all the rock was takin out of a previos tank so i had no cycle..Anyways i had a fluval 404 with fliter pads in there and carbon. i no that this will produce nitrates if not clean regulary which it has. Now will my water be dirtier without the fluval/ or will i need to do more often more water changes becasue no filter pads to catch detruis. Im thinking just to take it off! what would u do
