I have a 15,000 gallon fiberglass pool with east exposure. Trees block out the sun during the warmer afternoons. My recent test readings:
FC drops 2 per day. Is this excessive? During winter times I add 8-16oz per day of liquid bleach. Now I have to add 64oz a day. Its not that hot so far this year. I can't imagine what I have to add daily once it gets really hot. TIA.
