New pool perfect until this week, small amounts of green algae every day.

[Grey2175]

Numbers from today...

pH 6.8
FC 10
CC 0
TC 10
CH 100
TA 30 (tested twice)
CYA 70
TF-100 test kit
pump runs 24/7

Per the Pool Math site I added 4 lbs 12 oz of Walmart Borax just now.
Pool water is clear.

What is next?

Brush brush brush

+1. Get every inch of the visible algae to expose it to the FC, and keep that FC at 15-20% of CYA.

I would also do an Overnight Chlorine Loss Test sometime this week to make sure that the algae is not getting ahead of the chlorine.

Replacing some water to lower CYA a bit then I will take chlorine to shock level and brush and vacuum once or twice a day.
Is this a sound place to start?

Hope to have this back in shape before family heads here for Labor Day weekend. Thanks for your advice.

The more often you can maintain the shock level the quicker you will be done with it. Keep at it as often as you can, good luck!

Thanks! It turned around quickly. Back to normal.
