Based on the threads here about DIY
backgrounds, I figure I will try and make a series of rock towers for my cichlids. Styrofoam, no problem. Silicone no problem. Question, I know you can use concrete and paint but is there another product, an epoxy that you can use over paint to seal the styrofoam? If so what kind of paint and epoxy should be used?
Also along the same thought, can resin ornaments you purchase in novelty stores be coated in aquarium safe expoy to be used in aquariums? I have several beautiful castles and ornaments that would look incredible in my aquarium but are obviously unsafe in their current state.
Thanks in advance!!
