Balancing chemistry after pool resurfacing

[HiddenRiver]

Our pool was resurfaced in the late fall, we brushed and balanced (or tried to) then closed the pool for the winter. Just opened the pool this week. It was cloudy and green. The green is gone with the Alam but pH CH and Alk is way out of kilter. I think I balance pH first, is this correct? Also, trying to raise CH according to pool math and I just bought Cal-Plus. Anyone know what chemical this is? Lots of questions, as I know this balancing is tricky—advice welcome.

FC. 5
CC 2.5
CH 175
PH 8.2+
TA. 140
CYA. 30
CSI. 0.53

Floc does not rid your pool of algae.
Have you done a Overnight Chlorine Loss Test?

 

[HiddenRiver]

No, not floc to kill algae, to raise hardness but can’t log my addition because the brand name does not include chemical make up. Working on the chlorine too. It was 5 when I got up this morning. I have not done the overnight test. Worried about the new surface and raising chlorine too high especially with the pH out of whack? Could you provide your thoughts on what chemical constituents to take care of first?

The green is gone with the Alam

What is Alam?

Your pool resurface was months ago. You can SLAM without issue.
Follow the SLAM Process. Lower pH to 7.2. Raise FC to SLAM level.

Your CH will need to come up. Get it to 250+ppm soon.

Thank you. Do you know if Cal Plus is Calcium Chloride or calcium chloride dihydrate? Alam should have been SLAM

Does the packaging for Cal Plus indicate ingredients? Google does not come up with anything for Cal Plus

No it does not. First place I looked. Ah well.
