Water vacuum

[dreef]

I bought a wet dry vac that i use for my sump...it's mine and is ONLY for my sump

I use a piece if tube. It goes from in the tank a few inches to a bucket. If I pay attention and keep it in the middle of the tank and scare away inquisitive clown fish, it doesn't clog.

All the detritus etc can just stay wherever it settles. It keeps the clean up crew alive. In a year and a half I cleaned out the skimmer section of my sump once.
