SEACLONE!!! COUGH COUGH! Sorry i had something in my throat. But really i have no problems with my CPR bak-pak. it started collecting as soon as i plugged it in. But the best i have heard of is...
Deltec Ap 1004 with self cleaning capabilities
Cleaning the skimmers:
The Deltec skimmer has self cleaning capabilities. There is a brush in the neck of the skimmer that rotates and cleans the skimmer’s neck every 6 hours. There is also a cup flushing mechanism that rinses the collection cup every 12 hours. The only other maintenance that I perform is to clean the self cleaning brushes twice a month.
You can see this by going to oregonreef.com
But i think that might be slightly out of the $150 range
