Last night i asked several ?'s about building a plywood tank. Ended out finding answers to most of my questions on youtube. I now know that i won't need nearly the bracing that I tought, and have decided to use 1 end of the tank as a sump. I have been looking into different options as far as sealers go, and was wondering if this stuff would work? If it will that would save a lot of $$. https://www.lowes.com/pd/Seal-Krete...poxy-Actual-Net-Contents-123-fl-oz/1000074719
