It may be time to replace the cartridges in the Pentair Clean and Clear Plus. I have no idea how old they are, the pool is now 11 years old, maybe they have been replaced along the way, maybe not. We've been here 2 years, no info in the files about any new carts. Whether files are complete is unknown, seems to be.
A couple of the straps have broken, and they are pretty well discolored, rusty stains and grey that won't wash out. I'll admit that I have not soaked in dishwasher detergent, the 80 gallon size that might hold the 4 would be pretty expensive to fill up. I had used "Filter magic" to clean them but I can't find that the last few times I looked.
So, the question is, should I go with the same thing, Unicel c-7472 $61 online or $86 locally, or go with Pleatco PCC130 for $46.85 online. I need all 4 I think.
