Have two questions:
1. There's a pool output and spa output in the picture. What's the difference, and does it really matter if the spa returns are on when the pool mode is on (i.e., for the spill over / waterfall affect)?
2. The salt level shows 3050. But when I utilize the salt kit I purchased from TFP the salt comes in consistently at 4000. Is the IC40 incorrect, or is it measuring something different?
