Mustard algae and trouble keeping clear.

[JGeurin]

A couple of questions for the experts, which I am not. I’ve been battling all May and June to stay clear. I had a CYA and phosphate issue which is now resolved. Now I’ve got it to relatively clear but I can’t keep it there. My most recent tests are included. I’ve treated the high ph and the calcium since the test. Based on this group I believe I have a mustard algae issue and I’m convinced I should SLAM. So my question is since I have seen the chart, included, to treat mustard algae. So can I do all of these things together? If so what is the sequence. My understanding is….brush, Yellow Out, SLAM. Since this is my first SLAM any guidance is greatly appreciated. 16500 gallons in south Texas, in ground chlorine gunite quartz finish, extreme heat of 120 heat index’s lately. I have 12 gallons of liquid 10% chlorine on hand, 4 lbs of Yellow Out. Ty!!!

No, please don’t use yellow out. Take it back & get your money back/exchange it for liquid chlorine.

The first part of the prescription is the same whether you have mustard or regular algae - do the
SLAM Process carried out to completion at normal slam level for your cya
FC/CYA Levels
Then afterwards you raise fc to MA slam level for 24 hours only & follow the protocols listed here

After doing this if you’re convinced you truly had mustard algae you may want to maintain mustard algae minimum for sometime afterwards.
Do do all these things you need a proper test kit.

You simply cannot rely on pool store testing to do the slam process. It requires accurate testing multiple times per day until completed.

Yellow out is not something you want in your pool water and is not anything TFP would advise using.
