Actually there are some out there... some people use the Hagen foam filter sponges for their intake tubes. The ones that are for breeding tanks and the like. What I do for the intake tube is wrap a FLuval Sponge insert for their 3+ system and then clamp it with a magnetic clip that is desigend for holding large intake tubes (magclip is the name of the clip). I do have to cut down the sponge so there is only a small amount of overlap.
Also the tank I am putting the shelf idea in is a new tank that is 24" tall the 65 I have set up is 19" tall. There will be a pair of powerheads under the shelf to create loads of current for the plecos and the hillstream loaches that I want to put in there, so another reason that the shelf will be good... will help direct the current.
