I have both a pro clear 75 and a150, the 75 is a good skimmer, and I hav it under my 30 tall, It works great with a bubble diffuser. For the price, their great products the 150 pulls mad muck without the need of a diffuser(diffuser still boosts results though)
I think that Pro clear is a company in Jacksonville, so that may be why their is not to many people outside if florida who know too much about them.
