I bought this house about 6 months ago in South Florida. It has a gunite pool built in 1987 which was resurfaced with Diamond Brite some time ago. We bought the house from the original owners and it appears they didn't use the pool much over the past 10 years but always had it filled and maintained by a pool company. This is my first pool so for simplicity I kept with the same pool company. They come out once a week and do quick cleanup and balance the chemicals. The primary chlorination seems to come from the tablets in the floating dispenser.
We currently don't have a heater yet and the pool is in a screen enclosure and does not get large debris. It does get sun over the day but that is limited somewhat by the screen and some trees.
I am currently paying $85 a month for pool service and don't really feel that good about it. The pool water seems ok and I haven't noticed any problems with the quality of the water. I have noticed some dark spots emerging over the past 1-2 months and now I am wondering if it is black algae spots. The pool will probably get a makeover (resurface and tile) in the next 6 months.
I am looking to part ways with my pool company and take over. I got a TFTestkits
TF-100 delivered today and here are my results. The pool was most recently serviced by the pool tech on Tuesday morning.
Not sure if I will let the pool company finish out the month or take over now. How am I looking? If it is algae I am thinking I need to SLAM. I guess I should try the overnight test?
