As interesting as the rum threads are...can I ask a few questions about the CL200. I have one - doesn't seem to restrict any flow, but I trust what is said on this forum so could someone lay out the problems with using this product? One problem I've had in the past is that my heater had to be replaced after only 4 years and I'm wondering if it had anything to do with this chlorine feeder. The inside of the heater was a rusted out mess.

I'm in the process of keeping the chlorine levels very high to get rid of leaf stains at the bottom of the pool. I thought leaving the chlorine feeder completely open and full of pucks would help this problem? Maybe I'm wrong and causing more harm than good.
