So here begins my battel to lower the PH on our new pool, the maintenance guy has only been here once, I've been brushing daily but aside from the acid he added last week nothing else has been done to the water. So I'm taking the matter into my own hands. From the TF100 kit, my PH is AT LEAST 9, I've so far added 14 Oz of acid and is still high, let's see tomorrow. Also added bleach, completely missed the % option on the PoolMath app and added 62oz by mistake, should have been 40 oz, now I have plenty of chlorine, hopefully, the sun will help me lower it

Does pump speed matter at all when adding acid?

When I add acid I run mine on high (have a 2 speed) for about 15 mins or so to help mix it in good.

So you are in a battle with the pH. Here is your battle plan:
-Test pH
-Use Pool Math to see how much to add to get the pH to 7.8
-Add that much acid with the pump on high and maybe brush the pool as well to really mix it in good
-wait 30 mins AND TEST AGAIN!

Keep doing the above until you see your pH in the 7s. It might take a few rounds as we really don't know how high it is.

Also keep a close eye on your TA as it will be lowered by the acid as well.

Good luck and go win that pH battle!

On it! Pool guy came in, told him that I've been adding acid, he's like "yea that's ok" and BAM! Added a bunch of acid, maybe half gallon? He also added balancer and went on his way, now the PH is low low, below 6.8 for sure.

Electrical inspection failed because our fence wasn't bonded...Grrrrrr

This is what I'm referring to on the plaster, not sure if this is normal or if the plaster is supposed to be perfect, only noticable when the sun is not shining over the pool
