I've lived in our house with pool for over 7 years now. I've never had too much trouble maintaining it until now. Last year I had the pool painted with supposedly the best epoxy pool paint you can buy and had heard all the virtues of doing so. Our guntite was starting to look aged and I opted to do that as a cheaper option than a full replaster job.
At any rate, I cannot seem to get things balanced now. I stumbled across this website and have already started buying chemicals from a local chemical company instead of the pool store. That has helped. I bought one of the recommended test kits and I've now managed to get the pH, TA, CH and CYA balanced pretty well. But I can not get the chlorine level to come up. At all!!!
From the chemical company I bought a 5 gallon bleach container at industrial strength 12.5%. In an effort to get rid of an algae problem, my intentions were to shock the pool as advised. I ended up putting 3 gallons of the stuff in and it got the FC up to about 3 (when it should have raised it much higher). Laster in the day it was right back down to 0.5. Being out of bleach, I added 3 pounds of shock. This morning the bloody FC hasn't budged from 0.5. The pool is at least blue now (but terribly cloudy).
I feel like I'm burning through chlorine so fast I'm concerned I'll end up spending a fortune and not getting anywhere.
Let me know if you have any ideas. Thank you for this website and for any advice.
