Ok, just switched to bleach and according to the cya/chlorine chart I have to keep my FC levels really high to prevent algae. So, I have no choice but to lower CYA (I think). CYA snuck up so high because of the darn pool store telling us to add stabilizer and then to keep throwing shock into the pool. Our water just would not clear up and they kept telling us to put more and more in (7 to 8 bags of Dichlor shock every time we had it tested). On top of that, we were trying to maintain by putting 2 bags in each week. Plus, they told us to keep four 3" sticks in the skimmer! Every time it rains, the dag gum thing turns green again. Finally figured out it's because FC wasn't high enough for CYA level. UUGGHH!! Wish I had realized that a month ago! So, lesson learned and now 100% on bleach, no more dichlor shock from Walmart. I would rather add stabilizer as needed than have it included with every bag of shock.
CYA is registering at 100 on a test strip (I know strips are not good) but I think it is alot higher (going to get tested again tomorrow at pool store because I just can't afford $70 to buy the Taylor test kit right now). Any ideas other than draining half of my water and refilling?
According to the pool calculator, if the CYA is 100, I will have to drain and replace 60% of my pool. Will I be ok by replacing around 30-40%? What about the effects on my liner? The liner is 10 years old and in GREAT shape. We can't afford to replace it, so I need to do this as carefully as possible. Please run me through it step by step. We will be draining the old fashioned way (through pump as far as possible, then through hose pipe).

Thanks and please don't scold me too bad for not listening to you guys!!
One other quick question, while using bleach, do we need to keep chlorine sticks in the skimmer? Or is it just strictly bleach?
