Hey guys!!! Just got home from taking my son to school and the test tube water was pink again. It started turning a slight pink within about 3 or 4 minutes after I first did the test and by the time I returned home approx. an hour later, it was cotton candy colored. Is this normal or could it be CC? I'll put in a new filter this morning. Yesterday when I added the granular cya, after about an hour I squeezed the nylon until it was empty of CYA. Will I still lose much by replacing the filter? I don't want my FC to drop too low before I retest CYA in a few days. I think I'll increase FC by 2 or 3 ppm just in case, considering it's going to be sunny here today. Thanks!
Does anyone know the brand or site that sells these reusable filters???I believe there are "cleanable" replacement cartridges available for purchase on line (they cost more for obvious reasons.)
