Moviment MP40 missing on the sutface

[Tony73]

Hello

I've 2 MP40 pumps on the same side on a tank about 100 gallons, tank size 40x27x55h.

Tank Is visibile on 3 sides, pumps are on One short side, but using them about 85% with reef crest or tidal swell sutface Is not moving

How can I setup Better tò move also sutface?

Best regards
Tony

Reefcrest is a pseudo random setting. There's a good chance that it doesn't stick with one setting long enough to get the surface agitated. Try putting the 2 pumps in anti-sync and set them to a pulse or gyre setting, play with the times and intensity to see what it takes to get the surface agitated and then have the pumps swap.

If this works, I personally wouldn't have them set in that configuration all day, perhaps making them both in-sync for a period of the day as well as some other settings to keep the water flow sporadic.
