i have a fluval 3 for my 40inch tank,i have connected a spray bar because i find the current from it rather lively,its rather obvious where i have placed it because i have always kept the filter to the top of the tank with the outlet about 1inch below the surface ,its an internal filter and i wondered if i can place it lower in the tank so that some of the plants will disguise it. would appreciate any ideas on this thanks ,jackie.
