I am new to this forum but have been taking care of my own pool for 9 yrs now. I generally have done a good job. Now for the confessions: I usually use the test strips and bring a sample to the pool store every few weeks. I use Pinch-a-penny - they seem to do a good job and the numbers seem to correspond well to what I am seeing in the pool and on my test strips. It is a very busy store and they crank out a lot of testing and seem to be very proficient at it. What do you think? I know I am being a bit lazy and probably should be testing myself.
My Pool - 50 by 18 with 8 ft spa, gunite, approx 40K gal, 2-Aquarite 40K salt generators, Jandy 60sqft De filter and an ozone generator. Due to heavy rains and just getting back from a long vacation, stabilizer is currently low (20ppm). pH 7.5, total chlorine 4.0ppm, fc -4.0, CC -0, TA-70ppm, CH-325ppm, salt 3200ppm. I have just developed some small green spots of algae in the deep end. I am thinking about adding borates after reading here. Thanks for any comments or thoughts - Dan
