New Pool Startup Phase

[Green25]

Do these numbers look okay for the start up phase of a new pool? We finished filling Saturday morning and have not yet been released from the startup company; pool school is scheduled for this afternoon. We’ve also had a ton of rain this week. Pump has been running 25/7 and water feature ran for about 3 days straight after fill.


FC - 3
CC or TC - 0 I think (the was only my 2nd time testing and I need to go more quickly between FC to CC)
pH - 7.2
TA - 40
CH - 350
CYA - I can still see the dot at the very top, but I know the pool startup co added tablets to raise. We had 0 in the fill water I tested.

The pool startup guy cautioned against using the tablets and higher CYA levels, which I already knew from TFP.

Your CSI is very low. It really should be kept in the positive range with new plaster for the first 30 days. You should add baking soda to raise the TA and let the pH rise to the upper 7's.

Thanks @mknauss. I will ask the pool school guy if they plan on adding anything today and adjust if not.

Is it okay to guesstimate water temp until my thermometer arrives since PoolMath won’t calculate without one? It’s currently in the mid-70s after a week of mostly rain.

Sure. Your pool water temperature normally approaches the minimum air temperature seen that day.
