I checked my chlorine tonight and the test results are:
The pool looks slightly yellow/green instead of it's white/blue. Have been getting heavy rains the past few days. The SWG is set at 45%.
Any ideas? I might put a jug of clorox in to be safte (+7 FC). Also, I finished shocking last weekend due to algae hiding behind the pool light. All 3 shocking criterion were passed for three days straight.
The OTO test came with my TF-100 and is of the same age.
