Hi everyone! I have been lurking on here for a few months now. I just had a new pebble tech IG 13,600 gal pool put in, in may. I have been using a lot of acid at first but it seems to have tapered off. I use 30% so I just have to put a few splashes in every week. I ordered the TF-100 kit from the website. I should have donated! =) This site is the best. I had been using tri-chlor tabs all summer until now. I started to notice that I hard to start shocking it more and one tab a week wasn't enough. When I started out one tab was great. I have not had any algae outbreaks lucky. I just switched to using chlorine and bleach. BTW I love the FC test with the tf-100 its right now. No more guessing. Anyways. I tested my CYA and it was around 100 the lowest ring on the test tube. I looked up the FC chart and saw it was around 7 for that high. Thats way to much chlorine for me to keep up in my pool. My pool gets a lot of sun everyday. So today I did a partial drain and refill. I estimate I drained around 25-35% of the water to lower my CYA. I have not tested it again as I am waiting for everything to filter out. After reading on this site I finally understand why tabs are such a pain even though they seem so easy. I don't use my deck chlorinator anymore. Thanks to everyone for all there good info.
Anyways my question really is just about bleach vs liquid chlorine. I can get liquid chlorine for about 3.50 a gal. But bleach here in phoenix seems to be more expensive. I am not sure if anyone has any places they know of that are cheap in phoenix.
