This just popped into my head....a buttload of marine safe silicone mixed with white argonite.....will it cure underwater? The only other thing I can think of us to use my kids aquariums I bought last week....a 3.9 fluvial view...and a 4gal marineland that I've got cycling (with crushed coral from my fuge and water from my display to speed up the cycle....to house my clowns turbo shrimp and urchin while I drain the tank cement the gaps and let it re-cycle. The only problem is my wife would kill me for making her wait again. She was on the fence up until 2 weeeks ago about even doing saltwater and now she seems to be even more excited than I am
