I have everything I need to start my 45 gallon build.I have two 850gph Koralia Circulation and Wave Pumps,two,75 watt heaters,40 lbs of Caribsea Fiji Pink Arag-live sand,test kit and 80lbs of base rock(bought 40lbs and then saw a deal on amazon and bought 40lbs. Not sure yet if I will use all of it.) and egg crate for bottom of tank.Here is my problem,I bought Instant Ocean Epoxy to strengthen my "master piece" and it didn't strengthen anything I really want to start my build this weekend but don't know what to use to make the base rock structurally(sp?) sound.What would you recommend that would work in this time frame?
