Opening with very high ph and mustard algae

Water looks 100 percent better today and is very cloudy but no longer disgusting. I will get reading after work and buy acid after work. I ran the filter on recirculate last night but changed to filter this morning.

Hayward Sand Filter. S270T2. Pro Series High Rate Sand Filter

Jandy 2.5 HP Uprate pump. MHPU Series - could not find model number yet

Thank you again for helping me!

Here are the readings I got today. Put in Tabs in chlorinator as well as lots of bleach and liquid chlorine. Put in acid today as well.

FC 2.4
CC .8
TA 70
PH 8
Calcium 200

Given your low TA, I wouldn't try to push the pH below 7.6 right now. Have you tested your stabilizer level? That's critical to know.

Cya is 40

Then, till the algae is gone, try to dose to 15 ppm (15 gallons of 6% bleach) and repeat before levels go below 5 ppm.

First of all thanks for all your advice

Was away for 5 days and had to do what I could before I left.

FC and CC need major dose when sun goes down

ph 7.4
TA 50ppm
CH 130ppm

CYA - The black dot does not disappear even after I filled the tube to the top.

Thanks!
