I switched to fritz from instant ocean rc. I am finding the ph isn't what it was with rc. But I don't think it's the fritz salt. Normally I would blame the salte. My house is not a new house. Built in the 50's. Original windows are still in. There is no wind and just stagnet in the basement. I also turned off my heaters to the tank cause of the heat outside my apex sent me an alarm for 84 degrees. That was a month ago. Been staying in the 80 s. If it drops down to below 80 degrees then I'll turn my heater back on.
