What are you using to hold the bottom down? Just the weight of the rocks? Is it actually ABS or is it HDPE? I got a bottom made out of 3/4" HDPE once - I figured I would use the weight of the rocks to hold it down, and put a silicone bead around the edges to keep detritus out which was a good idea in theory, but silicone + HDPE = no good. Doesn't stick AT ALL - as soon as it dries it pulls back. |
I think its ABS, he should be okay.
