I have a UGF that always builds up algea in the tubes. I am wanting to remove UGF because its becoming a hassle pulling the tubes out to clean. I wanted to keep the base of the UGF in because didnt want to remove the gravel and redo the tank just to get it out. just wanted some opinions on this because wasnt sure when I did water changes if waste build up would just stay under the base where I couldnt get to it with the gravel vac when cleaning. Thanks for your help.
