I recently took back control of my pool, relieved my 'pool guy' of his duties, and think I can maintain my pool as well or better than he did. I spend several weeks / months (about three) away from my pool so I thought I need someone to take care of my pool when I was away. WRONG as my neighbors pointed out, my pool guy wasn't being as honest as he told me he was being. I put up a couple of game cameras from my deer hunting trips just to see how well he was maintaining my pool. Over a three week period he was at my pool once, then just to add a few tabs to my floater nothing more . No vacuuming no water test, notta. So I bought a robot, contacted some of my neighbors and friends, now my pool is vacuumed regularly, chemicals checked and looks great on regular basis.
I maintained a pool for a previous employer, for several years, a totally enclosed pool, no direct sun, heated to 92°, a real pain to keep balanced. I have already purchased a complete pool test kit, and been reading the pool school, post and other information on this site for a couple of years. Finally decided to jump in and become a participant rather than just a skimmer !
