This is my first post at TFPC, so I would like to thank everyone for all the help I've received while lurking for the past year.
Here are my current chemistry results: FC 6.8 TC 7.5 pH 7.5 TA 119 CH 94 CYA 70 (I just got my Lamotte test kit and am so happy to be rid of test strips forever)
Last year because of faulty test strip readings I added stabilizer to the pool when it wasn't needed. I've been working at slowly reducing the CYA level from well above 120 by frequent backwashing and filling and maintaining FC with cal hypo 73%.
As a consequence, CH has now dipped below 100. I am a little reluctant to add calcium chloride until I get the CYA down to 40 or 50, which could take another week or two. I just don't want to be flushing away $50 worth of chemicals.
Will my plaster pool be OK during the process, or do I need to add the hardness increaser right away to raise the CH to 250?
For similar penny pinching reasons, I would prefer to use up my substantial stock of trichlor and dichlor. Will using these products result in overstabilization again?
