Review on Seachem Tidal Polishing Pads Pack by Tommy Rao

Does exactly what it says on the tin. Polishes the water crystal clear. But it crashes FAST. Even in a relatively clean tank. I would suggest using this only intermittently, e.g. when redesigning or replanting, to clean the water of all that crap you pick up and then throw it away after a few hours when it's done its job. Good luck cleaning and reusing like other sponges.
