diy aquarium decor question
 
2 Attachment(s)
I started making my own aquarium decor using the styrofoam - concrete method. I have been trying to find a clear sealer that is water safe for my fish. I have been to Home depot & Lowes and they dont seem to know of any sealers that are fish safe.Any help would be appreciated. Thanks

Welcome to the forum.

OK, maybe I need to do a little searching but styrofoam and concrete? Is this the typical white foam that you can buy in blocks and then covered in concrete?

Wouldn't concrete leach lye into water? Do you seal the whole decoration, cause you wouldn't want to use silicone caulk for that.

Is the caulk to glue it to the bottom so it doesn't float?

I'm fascinated by this, I've never been happy with the size or price of pet store decor and gluing river rocks together makes for a pretty heavy assembly.

Its the foam insulation. I have seen this done by others.I am going to do more research.
