It's a learning process for sure
Next one I make I will be buying a plastic 1/2 in by 1/2 in squared light diffuser like they have at hardware stores
Cut some dimension to it and zip tie the pieces together. Then coat the squats with the plastic. The PVC pipe worked great but it just used too much material
I could have a whole background in my 250 gallon with caves , arches , and loops
I like the colors. But once it was under my lighting I needed to add some black to the rock as the purple is too light
I will defiantly make more
I'm also molding and casting corals
