Does anyone have recommendations for an algae cleaner that will not scratch an acrylic tank? I have a 535g tank that is a pain to clean. I saw on bulkreefsupply.com they have a brand called Free Algae and the product was Tiger Shark that can be used on 3/4in acrylic. Curious if anyone has experience with these or similar products. My challenge will be the 3/4in acrylic.
Thanks!
Thanks!
