My wife signed up last spring and i have switched to liquid clorine and use the pool math. Pool has never looked so good or been as inexpensive to maintain.
I have 2 new issues and am looking for help.
The pumps run in the day time but when I get up in the am the spa has drained, it is cold out and the freeze protection is on. Would the freeze protection cause the spa to drain? Or do I have some obscure valve or mode setting incorrect?
Second, I get an incredible amount of what looks like brown / tan "dirt" in corners or steps and edges of the pool and it builds if I dont sweep it daily. Could this actually be dirt or is it an algae of some sort. I have fought black algae before but it has not reappeared.
Any help would be great, thanks
