I've been a pool owner for about 2 years and have never had a problem with my water. I am assuming I am having an algae problem, but can't make any headway on fixing it. I have a test kit on order, so I am only testing with sticks currently. I have shocked once with 4 gallons of 10% chlorine along with 4 lbs of dichlor...FC still zero. Shocked again in the evening, no FC. Added a non-chlorine shock....still no FC. Added 4gallons and 4 lbs again...no FC. I have read pool school since doing all of that ( which my pool store owner advised), but I would think I would get some sort of reading on FC.
Test strip #'s:
PH 7ish...was higher before adding chemicals
TA 140 ish
CYA 0-20...lowest value on the strip
Any thoughts? I am waiting for my test kit, but until then should I keep dumping in Liquid chlorine?
