I've noticed that when I use Trichlor tablets, my PH tends to stay around 7.5-7.6. When I'm just using bleach as my chlorine source, my PH always wants to rise up to 7.8-8.0 so I'm always adding acid. I'm just curious why this happens. Looking at the pool calculator, I'm assuming this is why the recommended TA level is higher for a pool using Trichlor.
In my case, I'm trying a little experiement this spring using a combination of Bleach and Trichlor pucks. My theory is that I can use just enough Trichlor to keep the PH in check and supplement the additional chlorine needed with bleach. We get enough rain, that with bleach alone, my CYA level tends to drop over the course of the year. By using a combination of sources, I'm thinking it might stabilize my CYA also. I think I may have to raise my TA levels slightly to get everything stabile.
Any comments and has anyone else done this?
