Hello everyone! This is my first post on this forum and I know someone will have an answer for me. I'm new at this Salt water Pool and have found lots of helpful suggestions. So here goes: I have a Triton II sand filter and for the last few weeks we have been experiencing lots of rain here in Texas and the filter was reading 10% last weekend so we did a backwash and cleaned the in-line filter (not the sand filter) and the reading went up to 13%. Today it is at 0%. NOW WHAT??? any and all suggestions will be taken. Thanks in advance for your help.
