Like many others that I've read, I tried to fix my algae problem and avoid posting. All summer I've been seeing green algae groming in spots and simply shocked and scubbed, 2 weeks ago, problem got worse, green covering 1/2 the bottom of the pool (water clear). I read about shocking, scrubbing, backwashing, and pool was clear for about 5 days...now green growing in same sections! Today i bought a testkit recommended on the site and levels were noy way off...here are the info and #s:
Pool = 22275 gallons
DE jacuzzi filter
filter runs from 9am-5pm
pool in full sun 11am-6pm
FC= 3 should be 6 add 92 oz bleach
PH= 7.2 little low need to add 26oz soda ash
TA= 60 little low need 75oz baking soda
CYA= 55 did 2x cause seemed very high
I know FC should be around 6 for my #s, but my frog chlorinating system is on the highest #. The info said to add 92 oz bleach.
---If my chlorinator is already maxed, how will i maintain the appropriate FC???
---Can i put in a pound of shock powder instead?
I never had a problem like this before and it is making my retreat a prison sentence! What am i doing wrong???
*I did move the filter this year about 60 ft away from pool, but didnt have an effect on filter operation
*I have 2 dogs that are in and out of pool
