So I am really struggling to get my redsea E260 levels consistent. I swapped the valve to a gate valve and have a COR15 return pump. I see I have 3 things that can change the level in my sump / display.
1. Cor15 IQ level
2. Cor graph level
3. Gate valve
Which of these should I change? How does COR IQ play with the value on the graph?
