Bought a new house in June and I've been struggling to keep the pool reading chlorine levels. Pool stores were no help so far except of selling chemicals that did not work.
Just received my new TF-100 kit and the results so far are enlightening.
Stats with the new TF-100 so far:
Old owner used clorox pucks and clorox shock(1-2 bags a week).
I'm assuming the high CYA is causing my chlorine issues. Green algae is now also blooming in the pool.
Is my only remedy at this point to drain water from the pool and reset and then SLAM? (PoolMath seemed to indicate 60% of the water would need replaced. Ugh.)
Thanks for any help or advice.
