I have a 10000 gal in ground pool with a plaster surface. I was informed that I should add a conditioner to the pool. I currently have what appears to be mustard algae. There isn't any floating algae. I've gone between two pool service companies trying to learn what they do and am getting conflicting responses. Latest paper test strip results shows 7.8 for pH, 0 TC, 0FC and 0 stabilizer. If I must add conditioner, do I then proceed with SLAM process?
