Looking to do a couple dividers in my tank and was wonderin what silicone i could use?.. i only have a Home depot in my area bought a peice of .220 Acrylic to use and right above it i seen that they had some 100% silicone right above the acrylic is that safe to use? If not what is the safest can someone point me in the right direction of a safe useable silicone for use in my dividers...
