I have an inground 18by 36 pool with roman ends. 30000 gallons of water. vinyl liner, cartridge filter, pool pilot swg 1 3/4 pump. No heater. I woke up today to some algae on the bottom and on the walls.
My salt level was 2500 so i added 120 popunds of salt to bring it up according to the package 480 ppm so it should be 2980. The slat level is tested at 3300. i got morton pool slat from walmart. First time I used there salt I always used pool store salt. could that salt be bad?
cya was at 25 i added on monday 3 pounds of cya should bring it to 35. i havent tested because they say cya still can take a week to totally dissolve.
I orderd the tf100 kit. i am using a walmart kit that tests ch ta cya and ph and fc. it worked well for me till i added the salt adn cya..
will adding 2 gallons of liquid shock be okay to start to kill the algae? willthis also raise my cya up? i read that adding shock will raise it. i dont want it raised much more or have it go over 100ppm. it is a slight algae and only in certain areas of the pool. i think my numbers seem to be okay. also for a swg i was told to get a certain type of chlorine i think it was hypo chloride or something like that. please help me out soon.. like i said i thought my nimbers were pretty good so where did this algae come from????
