Thought of that, but with stuff growing on the bottom, you impair or lose the ability to siphon out crud.

We do our siphoning in two stages, beginning by removing the powerheads to be cleaned. First stage is to siphon out the crud that is easy to get at. Second stage is we get out the turkey baster and blow the crud from under the rock to the back of the tank, then siphon out that crud. You can't imagine how much extra crud we siphon out during the second stage, probably more crud is removed the second time than the first
