umm i hate to say it but im pretty sure u need to start over. every build i have seen was painted and dry locked before installation. unfortunately i think you may be in for some unforeseen issues with leeched chemicals, i could be way off but that's just my opinion. i hope it ends up working for ya.
I would be more concerned with the idea of securing styrofoam with suction cups :study:
While it sounds good in theory. If you come home one day with fish on the floor it wouldn't surprise me.
If you plan on keeping a lid with lighting that also might be a hazardous situation. :affraid:
Also I'm certain you don't need to use any epoxy or sealant considering that drylok itself is a waterproof sealant.
Lastly,while it doesn't really matter if you coat and color your 3d backgroundout of tank. It is considerably easier to do so.Drylok will not leach anything when properly dried. one of it's benefits over cement mixture.
