Last year I used a combination of liquid chlorine and an overuse of trichlor tablets. Not surprising to most in this community, my CYA was at 100 when I began preparing my pool for spring temperatures, resulting in having to drain half my pool. Current CYA is 55-60 and I'm happy to say I'm divorced from trichlor forever.
The question I have for those who have a similarly-sized pool located in the Southwest and use liquid chlorine exclusively is: What do you spend monthly on LC? I purchase a 10% concentration at a local pool store for $8.00, which is a box including two 1-gallon containers.
