just moved in and learning about pools, i had the pool drained, refilled,shocked and all seemed ok but at this time all i have for testing is 4 part test strips( ph, free chlorine, total alk., and stabilizer.) ph is 7.8, alkalinity is 80, stabilizer is low, but the free chlorine is very low,(0) the pool store down the road tested my water and said all looks ok, no contaminates, i called them about test strip staying white on free chlorine and he said that part of test strip was probably bleeching out on strip, i havent added any chlorine at this point. so next day algie starting to show up in pool, i brush cleaned pool, i put two 3 inch chlorine pucks in skimmer, overnight, test strip still reading the same,i cleaned out my filter in pool room it was really full of yuck, i thought pool people did this when they drained pool but they didnt. i did a backwash which i dont fully understand yet, when i turned on the circulation pump brown water came out in pool, well i went out and got a gallon of clorox and am now at my main question of how much clorox should i put in pool and what else can i do? i plan to get a good test kit but not till weekend, budget allowing. help appreciated
