when i tore down my last tank, i kept all the equipment that I was able to reuse for this new tank. the equipment has sat for a good 4 years, unused. i read that you can use a white vinegar/water mix to let the equipment soak. on the other hand, i have read, and been told, that the white vinegar can damage the o-rings/seals in the pumps, skimmers, etc. SO, what is the best way to clean this equipment without damaging anything? I would certainly like to avoid having to dismantle anything down till its in a bazillion pieces, just for cleaning. can this easily be done by letting the equipment run in a "water mixture"?
