Helping a friend while he's on vacation. Before he left, he asked me to come over and look at his pool which was a bit hazy. I started a SLAM and it removed a high level of CC's and got it clear rather quickly. Unfortunately, I can't pass an OCLT. I just checked this AM and I'm still losing 2.5 ppm of FC overnight. In addition, I lost about 7PPM during the day yesterday. Pool is 30K, Vinyl, Cartridge filter, single speed pump. It has a Paramount In Floor Cleaning System that has been mothballed. The wall jets have been capped and has never been used by the present owner. Thus far, I have removed the ladder which had algae under the steps. I also removed his robot until it can be taken apart to see if it is also harboring algae. I have brushed everything. My remaining areas of concern are two lights, the floor drain, and the in floor pop ups (about 9 I think). Am I correct in thinking these old pop ups could be harboring algae? If so, is there any harm in popping them out to check? I can't locate a tool on premises, so any suggestions on how to remove them or what tool I need would be appreciated. Thanks.
