If your CYA is in the recommended levels, then you need to stop using pucks or the CYA will get too high.
Opening the Pool, what goes first?

As far as I know my CYA was always lower then recommended, even last year tests I see readings between 50 and 60 at most. Right now I am at around 40-50 and I am not adding anymore. My chlorine just seems to have a hard time dropping. I did test around 11 today and it dropped to about 15 though, still seems like its dropping very slow with no extra production.
Here are my latest results:
FC - 9.5
pH - 7.2 (still not moving?, I thought below 10 FC it should read ok?)
TA - 100
CH - 300
CYA - 50
My pH has not moved at all since I started shocking early this week, is this a reliable reading or at this FC it could still be off? I guess my main question is can we swim in the pool? if not I really do not want to add baking soda as my TA is already high, maybe I should try to turn on the bubblers in the spa, that should raise the pH? I have always had a high pH so this is new to me.

Your pH is fine. Baking soda does not affect the pH much. You should use borax or soda ash to raise pH if required.
Swim away.

Great Thanks
I thought Baking soda was Soda ash for some reason where could I buy soda ash, is this one of those regular grocery store items? Borax would be a great idea from what I see on Pool School but I do not think I have the test for it. If I wanted to start using borates, what test kit do I need ?
Washing soda is the same as soda ash and can be found in the laundry aisle. Borax is also used to raise PH. I usually use Borax to raise PH unless my TA is low. Raising to a certain number PH wise with Borax will raise the TA by roughly half of what Soda Ash will. Baking Soda is used to raise TA. Baking Soda has just a slight impact on PH.RafaelSvr said:jblizzle said:

Hmmm sounds like they will all raise my TA to an extent, maybe I will give it a while and see if it rises on its own given my TA is already a bit on the high side.

Poolcalculator can give you solid estimates. Were you successful? Usually with higher TA you can aerate the water to get pH to rise more quickly.RafaelSvr said:
