I'm actually still in the SLAM process. I have had the worst time with running our of testing reagents. I at first didn't have the FAS/DPD test kit and when I received it, I ran out of the reagent 0871 within two days. I received the 0871, but I've been waiting on more cyanuric acid for a week and a half. I ordered from pool supply world and it was on back order. The last time I was able to check my CYA it was at level 30. The CYA reagent should be in tomorrow, and I will test it again.
Do you know what the brown stuff on the bottom of the pool is? It's the first two pictures I posted. it's not grainy when I touch it and it goes into a cloud when I sweep it. I was able to manually vacuum it all to waste today. I am curious if it'll come back tomorrow. Is that a sign of dead mustard algae?
