Odd issue with speed on low setting on vs pump

[supercanadian]

This is pretty odd and no idea how to diagnose what the issue might be....so you'll see in my sig my full setup...omnilogic, vs tristar pump...etc.

So I've noticed this year on the lowest setting on the omnilogic either at low or at custom setting for pump speed that the volume of water that will come out my waterfall is higher by about 30% from last year. No change to equipment or settings or software. The pump sounds about the same low noise running. Odd stuff.

Not sure if can set the accuator to do half the water to the waterfall and the other the jets, i seem to have either or option not a mix of both.

Oddly as well that twice this week when i set to waterfall the water flow was perfect same as last year then later in the week is back up higher rate of water output.

Cleaning the filter can change the water flow. Is the filter pressure any different?

Just and update....I did fix this issue. Was pretty simple the omnilogic had defaulted back to the standard flow rates of a minimum of 1500 rpm and I set it to 1100ish and the waterfall is back to normal! sweet.
