Could maintaining too high of a chlorine level cause the filters in my pool equipment to become completely misshapened with some cracked plastic? I have a Purex Triton Clean and Clear Plus. I just replaced the filters with brand new (Pentair) in August 2007. The previous filters lasted 6 years. I am using bleach and keeping my levels between 7-10 the majority of the time. When I first contacted your site, I was having continual algae issues (which are now completely resolved THANK YOU!) so the chlorine levels at that time may have been kept higher. Of course I have all my other chemicals at the proper levels also and I added borates which I check monthly. I am having to replace the filters, which is not inexpensive, and I want to make sure that I do not have the same problem. Any ideas?
