Well, I didn't test the water today. I drained it down to about 24" and scrubed and scrubbed. It came off and then I vac'd with it on "waste" and dropped it to ~ 18". Looks a lot better and am refilling now. I just for the heck of it tested the hose water and the FC was 5 and the PH was 7.8. So we will see what it is in the a.m. BTY I'm using a Walmart AquaChem 6 ways, it that good enough or should I go to a Taylors or something else?
Have a good night.
