I have a large stag colony that I lost due to AEFWs and rather than just chucking it i figure it will make a good hitch for a seahorse tank and might help to color them up. I want to paint it so it won't grow algae as easily and it will be easier to clean when algae does grow on it. I have access to automotive finishes but not sure if they would be reef safe. I want something that will be more durable than a rattle can paint job, anyone have any ideas on what would be best to use?
