I know this is probably a dumb question and im about 99% sure i already know the answer to this question but, is there such a thing as an aquarium safe cleaning product? I recently bought a used sump filtration system from someone on craigs list and it had been sitting in his garage for a few years collecting dust and dirt. I really wanna get it cleaned well before i incorporate it into my system and was wondering if there was anything that could help me out with this or if its best just to start scrubbing.
thanks
