THANKS! I have a question for you. How often do you vacuum your pools? Why do you vacuum them?
A little back info. about the question-You can see from my signature that we are new to this pool. I have been doing BBB from the very first drop of water in the pool. Every thing is going GREAT! I can/do pass the OCLT when ever I test for it (did it last night in face). BUT every day I see some brown/gray stuff on the bottom of the pool. Some days are more than others. It is never much but it is there. I really think it is dead algae as it is not grainy and is very easy to vacuum up.
Test results are from PM test after adding the evening chlorine
FC 7 (goes down to 4.5 during the day-full sun 10 hrs.)
CH? Vinyl pool so did not test
We have little leaves/debris in the pool most days. Pump runs 10 hrs day.
So is my pool normal with having some "dead algae" every day?
Thank you SO much for reading this!
