Using tablets as a supplement for granular?

If you use trichlor and dichlor without periodically checking CYA levels, you may end up with algae because as CYA increases, so must chlorine. Take a look at the Best Guess Chlorine Chart in my signature below for more info about that.

Thanks, I probably should get a more comprehensive test kit like the one you mentioned. Better safe than sorry, after all.

But, with the tablets, is that the 'proper' way to use them, as a sort of supplement between less-frequent chlorinating?

Some people use them as their only source of chlorine until their CYA gets too high and then they switch. Some people only use them when they go on vacation. Some people use them along with other types of chlorine. There is no one "right" way to use them. Personally, I don't use them. I use only bleach and just add my CYA separately when I need to increase it.

I decided to go ahead and order the K-2006C testing kit so I can keep better track of my chemical levels. Since it won't be here for a few days, I got a pool store water test done. They say my calcium hardness is low at 100 ppm, total alkalinity is low at 60ppm, and that phosphates are high at 200ppm. CYA tested at the lower end of normal at 30 ppm.

They wanted me to buy a bunch of stuff but I wanted to come here and see what you guys have to say about where I should go from here. The pool is looking fine so there's no rush. Would it be better to just wait for the kit to arrive so I can take the measurements myself?

Thanks

You have a vinyl pool. No worries about low calcium. Pool stores are notorious for trying to selling people calcium when they don't need it.

Yes, just wait on your kit.

This is a good question and one ive been wondering about myself. I am strictly a granular user, hth from walmart. Iv'e noticed my ph starting to rise and was wondering if tabs could help me with that. i may try some.

Bosch, be sure you test your CYA first to make sure you have room for any increase since those trichlor tabs have CYA in them.
