The feeder has never been a problem for me. The flow through the feeder is fine, the tablets are dissolving just as they should, I'm just not able to get any reasonable level of chlorine out of them.

The more thought I give it, the more I think I'm going to have to just pickup a new supply of Tabs from Leslies - they're 20% off right now anyway.

I also recently installed an offline 320 for my sister-in-law on her pool, and she's had great success with it (using Leslie's tabs). The past 2 years she had constant problems using Cal-Hypo tablets in the skimmer.

Thanks for the reply.
