I have been bitten by the cold water hiding the salt content. We had a very wet fall and winter. My swg has been reading about 1600. The few times I've turned the pump on (for cold nights) I've run it at 0. Last weekend I decided it was time to bring the salt level up. The poolcalculator said 380 #'s. I bought 10 bags of 40# and put 8 in. I checked salt last night and it said 7600. The salt strips appeared to agree both times but I have a hard time reading them.
What is the downside of just letting nature slowly wash it out with spring rains? I imagine it would only get down to 5000 by summer though. If I'm going to pump out water I need to do it now before I bring my other chemical levels up.
Also, if I have to pump out water, how do I do this? I have a cartridge filter so I never backwash. I don't think I can use the pool pump. I imagine I need to rent a pump to get the water out.
