Opening with very high ph and mustard algae

[greenwich3]

An hour after adding chlorine and bleach, my chlorine level is:

FC. 9.5
CC. 2.5

This was my first time using the k-2006c so I will have to learn how to use it correctly.

I guess I will see how things look in the morning.

Thanks!

Get some acid -- you need to get the pH down below 8.0!

Also, we'll need make/model on the pump and filter in order to offer better advice.

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.
