Solution to pH Problems in Pools: Guide to Using and Buying the BSPool Evo pH Probe

Customer:
Hello. I have a saltwater pool and a BSPool Evo pH controller. I need a new probe because it shows 3 no matter how much I clean it, even though the pH is very high. I don't know if the pH probe for PoolBasic Evo Double Reference PH-1-3-2831. Brand Sonde pH redOx would be suitable.
My mobile number is 667451033.

Good morning.
On the 5th, I ordered and paid for a pH probe for pools (YDSHWWKAN). They told me it would take 6 business days and it's already the 18th and it still hasn't arrived.
The probe is pH probe for PoolBasic Evo Double Reference: PH-1-3-2831, and it is very urgent for me.
