Hello everyone! I've read several threads and you guys are awesome! A friend told me about this website and i love it so far! I just opened my pool for the first time! I have a intex 18x9 rectangle pool 52 inch deep and it's a sand filter with salt water generater! Last year i had trouble frequently and spent hundreds at the pool stores on shock, algecide and stuff like that! It occasionally would turn green and get a film of green slime on the sides that I'd have to try and vaccum out and shock! I know nothing about this and im learning. Anyways i left it up all winter half way full. 3 days ago i raked out all the leaves, filled it up fully and poured in 2 gallon of bleach! After a hour it wasn't black (from the disintegrated leaves) so that alone helped! On day 2 i hooked up the sand filter to get things moving around and have been backwashing several times daily. Pool still cloudy but looks soooo much better! Yesterday i put a bit of borax (1 lb) , 1 more gallon of bleach and baking soda (1 lb) just for the jerk of it i guess! My current readings are Total hardness 250 , Total Chlorine 50, free chlorine 0, bromine 2, total alkalinity 120, PH 7.6. I am having a hard time understanding the pool calculator! Ugh ... Help please! My pool is about 4,800 gallons. Thank you everyone!
