i rasised it 2 inches with the mounts in side...i'd like to get it up about another 5 inches, it would not cove the rim...but i'd like to fix it that it will cover it
I was going to suggest just putting spacers made from wood to raise it,
But if canopy doesn't cover the plastic rim of the tank at that height it would not look as good. And would not be as sturdy.
So a diy canopy would be in order.
