- So, Krylon changed their tried and try true for aquariums fusion paint to a fusion all in one paint and primer. I called the company and they confirmed that it is not the same. I saw a video on YouTube with a kid using valspar for plastic in in his freshwater tank. A) I’m not sure if that would be fine in a reef and B). I can’t find it anywhere. Lowe’s switched to Krylon from Valspar. Anyone have any experience or heard of a new pain that is reefsafe inside the water? Thanks.
