So I have owned my pool since march2014, but it has been open since may. So far, everything is great due to BBB. I have to confess though, that when I first started I did not know what I was doing so I ended up with a giant 40 lbs tub of 3in trichlor tablets from lowes for $89 (I know cheap). I never added any CYA since I started. In order to use them up, I have been doing a hybrid approach. I would add 2 tablets every time the other 2 dissolved. In addition to that I would add 12% liquid chlorine (get it cheap from pool store) instead of bleach. I add baking soda if my alkalinity is low and of course borax to raise pH. I have not had to do it too much though. My water is crystal clear. So far, since I dilute my water by having 2-3 people doing water bomb dives into the pool regularly and having to fill from the hose, my CYA has been somewhat stable (in the 50-60s). My pool stays open unil sept. and then I close it around labor day. We get rain and snow, which will add more rainwater anyways while the pool is closed. Can I continue my hybrid approach as long as I can keep CYA in check? Once I use up the tabs, I plan to not buy anymore. But if this works for me, can I continue with tabs, as it allows me to add the liquid stuff less often.
Please disregard the debris on bottom, i have to vacuum this weekend.
