Does anyone know where to buy these? It seems impossible to find them! I've heard good things about them and wanted to try them out
yeah these are the ones I'm using now but I think they use different sponges because it clogs up faster.Marina makes a sponge filter that uses sponges that are very similar if not identical to the old Brilliants.
Using these as well. I have the full sheets.
I'm also using these.Just get yourself a hydrosponge; they're a better design, easily available, and probably a better price too.
