Just ordered the TF-100 today and I was wondering if there is anything else I should order online while Im waiting? I have had the pool for 4 yrs (its about 10 yrs old though) , and seems like everytime I get things looking good I get another algea outbreak. First off, I have added very little if any sanitizer since I have owned it (never had a way to test for it). I have a bottle of SUN conditioner and wondering if I should just throw that out (its old). I have added over a gallon of MA in the last week and pH keeps going back up to around 8.2+. I also tested my Acid demand today (using the homedepot test kit) and it came out around 200? I have also added alot of Chlorine in the last month or so and doesnt seem to be helping either. Also, in the last month or so, I have noticed my swimming trunks and towels have a musty smell to them, never had that problem before now.
