I checked out a newsgroup and managed to buy a 2nd hand one for £25 and soon learned why. I even bought a Pro upgrade kit and it only made it a bit quieter but nothing any more efficient. I put up with it until I found another skimmer on eBay. I bought an Aqua-medic Turboflotor SL 1000 Multi for £80.
much better buy so it was.
