I use the replacement sponges from Marineland powerheads and theyve never shrunk at all.
I use AC 70 foam and no shrinkage so far.
Any place that sells or sold Aqua Clear filters.Where to you get that? Sounds cheaper!
I bought it long time ago from Ken's Fish but, as "dbosman" mentioned you can get it at LFS. You can make about 6 sponge prefilters from one box (3 in a box) of AC70 foam. I paid $3.99 for one box. Lots of good deals coming with the holidays I suspect.Where to you get that? Sounds cheaper!
Yea well you were right, but I had actually forgotten that I even tried that prefilter on the main intake. I am surprised how well it help up after being in the tank for while!Those are the sponges that I mentioned earlier. I used the smaller piece to plug the hole (a piece of the smaller one). These things will last a long time.
