Can I use regular 30min 2 part epoxy to glue some sand to tank bottom ? I dont like when powerheads blow sand from bottom glass and I can see it like mirror. Thought may be painting glass with very thin layer of epoxy and pouring some dry aragonite sand will solve problem.
Othervise I keep very shallow layer of sand, as was frightened by amount of stinky sediment buried in sandbed when was removing it from old tank. Now I keep stronger water movement around bottom, but that causes another disadvantage
