Sounds good, but "ideal"is not really a reading. "ideal" pH can be anything from 7.2 to 7.8, but usually 7.3 to 7.6. If your pH is 7.5 or higher, the trichlor tabs are fine. Even if pH is lower, you can still use them but always have a box of Borax around so if pH dips to 7.0 or less you can immediately add the Borax and bring it back up. If your T/A is also very low, you can substitute Arm&Hammer Washing Soda for the Borax and it will bring up your T/A as well as the pH.

In any case, when using Trichlor tabs, you need to watch your pH at LEAST daily and your CYA weekly.

The one thing I like about Trichlor tabs in the spring or in a new fill is they erode. This means that you are getting a constant flow of chlorine into your water and there's no chance of FC dropping to zero.

I opened to fairly high pH, green slime and no CYA. After a mega-dose of LC to clear most of it, I used up all my di-chlor, which adds CYA and lowers pH, but not as much as Trichlor, then filled up my floater with left over trichlor tabs. Over two weeks I raised my CYA to just over 30ppm, added two boxes of Borax and one of Washing Soda, and now have a stable pH of 7.6 (hasn't changed in almost 3 weeks), a CYA of 30ppm, an FC of between 3 and 5, and a TA of 60--yeah, that low. But, since my pH is stable, why should I mess with T/A? After all, its JOB is to keep pH stable!
