Hi, I am so glad to find and join y'all! We have spent an ungodly amount of money at the pool store, and can not get rid of the mustard algae. I am anxious to try your way, but am afraid I will need guidance. I did my first test with my new TF-100 kit and these are my results:
If I am reading the pool calculator correctly (and I am not sure I am), I need to add 15 121oz jugs of 8.25% bleach for mustard algae shock levels. I am supposed to add the bleach all at once, right, not gradually over several hours?
It states I need to bring my pH from 7.2 to 7.5, but in Turning Your Green Swamp Back into a Sparkling Oasis it states to start out with pH on the low side, so that would mean the 7.2 would be ok. Is that correct?
Also from the above mentioned thread, my CYA should be brought to 90 to avoid needing huge amounts of chlorine. But I am going to be adding huge amounts of chlorine anyway for the mustard algae. Do I still need to drain/refill to get the CYA down?
Do I need to reduce the TA and CH also before beginning the algae attack?
Our water is clear, with some patches easy to see on the wall/floor, and some only visible in puffs when I brush. I have tried to read most of the pool school and a lot of threads, but I am a lot overwhelmed by all of the information, and I am not sure I am using the calculator correctly.
I think our auto chlorinator is not working properly since we have had to add so much dichlor this year. The pool place recommended taking it apart and blowing it out with water, but they did not use connectors when they put it in, so we will have to cut the pipes and buy/attach connectors to hook it back up. I am not handy, and my husband has not had the time to try to do this. After reading here, it seems like we should not go to the trouble and just put an empty container of pucks in there and not worry about it, and just use bleach daily instead since we have pretty much been adding dichlor daily. Any thoughts would be appreciated.
Sorry I have so many questions (I promise I have tried to read), and thank you so much for your help!
