So I was going to be gone for a long weekend so I bumped FC to 20 last Friday evening to compensate for not being around for 3 days to test. Didn't want to chance the green lagoon again. When I got home Monday night I tested again and FC was at 2ppm. I have 0 cc, and clear water, no algae present. My OCLT was 0. I'm testing every other day and having about 5ppm loss every 2 days(aiming to maintain 7ppm). I do not mind adding a half gallon of 12.5% every couple days but I'm concerned because I will be out of town for 9 days and have no one to keep an eye on it. CYA is at 45 (subjective but based on TF100 test kit sample pool water). What do you all recommend to keep my sparkling pool intact while I'm gone? And doesn't the daily loss seem excessive? Let me know if more info is needed to make intelligent recommendations. Thanks!
