I ws going to hold off on this but I do have a question or two. I pick up my 96x36x24 acrylic aquarium and 72x24x18 acrylic sump from acrylic creations tomorrow and have a question about some pumps I have. My buddy got me 2 two little giants 587600 from his job that where used to pump bleach. I will neutralize and clean them. But will they work or should i get different ones?
