What Should I Do First, Treat High pH Level, Add Salt or Add Conditioner(cya)?
by Sandra H
Chlorine: 0/0 reads really low
Cyanuric acid: 30-50
Salt: 1900 ideal is 2700-3400
I would like to know what I should address first, lower pH, add salt or what order is best.
Thanks for the question Sandra
I want to address the readings to be sure I have them correct. The total alkalinity (TA) range is between 18 - 240ppm. That seems to be a very large spread. Can I assume it's 180 - 240ppm. If it's this, then obviously it's very high and needs to come down.
I will also assume you have a salt pool. The thing that stuck out at me was the very high hardness level. This can't be good for your salt chlorine cell. Normal range is between 150 - 250ppm, but mostly for plaster pools. Vinyl pools can get away with 80 - 100ppm hardness and anything more is a waste of money.
If you do have a chlorine generator I would recommend decreasing the hardness now. You're running the chance of it calcifying and burning up. The best way to reduce the hardness is a partial drain and refill. There's no quick or fast way to do it, a drain and refill is needed if the hardness is at 1000ppm. I will assume the readings in the question are correct.
Even if you drain 3/4 of the water you're hardness is still going to be at 250ppm which is the top of the safe range. If you have hard fill water it will only increase. If not, your best bet is to do a full drain and refill. The salt cell at the Y pool where I was the pool operator burned up when the guards used too much calcium chloride. You can also have pool water delivered to you.

You can balance the chemicals perfectly but if you don't get the hardness down to an acceptable level you're going to keep buying expensive chlorine cells.
Again, my advice is to do a full drain and refill, then take the readings for the fill water, and we can go from there.
If you would like personal assistance, I do phone consultations for a donation of your choice. It makes things go much faster. If you choose to not go that route, we can correspond by email.
Hope this helps and have a great Summer.
