Mp40 issues and questions

[BwA_TR82]

So I'm having a few issues that maybe somone here can help me with. I have contacted support no response yet. But here is the issues. I have 4 mp40s in my 240g tank. But even at 1% on each pump the flow seems to be tremendous. Also when I put them in gyre mode 3 of the 4 never completely cut off the flow. Instead they stay running low speed then ramp up. The 4th mp40 in gyre mode cuts off
Flow completely then ramps up for gyre sequence. They are connected to mobius. I have removed them and reinstalled them didn't fix the issue. I also performed a hard reset on all 4 through their controllers Didn't fix the issues. Also when I pair them as child in anti synce they are not running the schedule apposed to one another. What can I do to fix this?. It seems strange that 1% power the pumps are so strong. Any help would be greatly appreciated.

If I'm remembering right the pumps will only go down to 30% speed at the lowest running option outside feed mode. I surprised you think it's too much, I run 4 mp40s in my 120gal all running up to 95%.

I'm also surprised myself. But they are very strong lol.

Where are they placed?

Where are they placed?

On both the ends of the tank top and bottom

Mine go down to 1% when I need them to and run at 25% during the day.

I thought these can go as low as 1%. Unless its only certain modes.

If you find the flow too strong even at 30%. I would look into 3d printed parts to change out the flow profile.

You can adjust them to that low via the app but this has come up before, they don't actually run down beond a minimum speed.

Mine run at 25% during the day and 18% overnight. The GPH is clearly readable in the app and the flow difference in the tank is clearly noticeable. I am running reefcrest mode. Perhaps another mode has minimum levels of operation but not reefcrest. I have run them as high as 45% and various speeds below that too.

I have 4 MP60, two in each end, and in Gyre mode the pumps not running stops completely. This means i cannot use Gyre mode as my Damsels will quickly hide in the pumps as soon as they are not running (= Damsel sushi).
Don't know how to set a minimum speed in Gyre mode.

Cannot set Expanding pulse to any thing useful, and Ecotech instructions only cover Long pulse which is not an option in Mobius.

does anyone have any answer for this? It's very odd that 1% power seems so strong. Omnglad I didn't go with the mp60s lol

I have a mp40 on my 75g tank, and ran it at 90% for the last 2 days. So it’s very odd indeed that 1% is too much in your 240g, even if you have 4 of them

Have you tried running a software update on them through the app?
Other than that, maybe try resetting them - seems strange.
I have a 220 Gal, and run mine at around 50% - but they are on the rear wall.
