No so random randomness wave maker

[Tangdora]

So I recently added 4 jebao mow 22 wave makers to tank. While these things are cheap they are certainly powerful I’ll give them that. They only come with 4 modes. Constant, wave, sine and random. My ideal scenario would be to run them in the random reef mode. But after I comparing the watt draws over a period of time it would appear that the random mode actually tends to favor towards the lower end speed of the pump. I have two plug into this would and each have an max draw of 50 watts for a total mak draw of 100 obviously. Both the sine and wave modes seem to on average run slightly above avg speed so will probably be running in one of these modes now to get a bit more flow

Not looking for any fixes I’m just more curious if anyone has data to share on how random modes stack up on other model wave makers. if this mode was truly random I’d expect to see an average closer or even a tick above 50 watts like the other two modes and even some extended periods of time where the flow remains above average for a period of time or vice versa and not back and forth across a mean with the occasion spike outside a deviation range

Appreciate any input
Thanks

I didn’t think much effort went into making these things truly random, but that’s just the cynic speaking.

yeah especially the Jebao brand. But I was able to get a bit more randomness by randomizing the programming of the various modes. Used the random function in excel to select what mode to use at a given interval to remove user bias. Set it to drop to the actual reef random mode at night when fish are sleepin. But during the days it’s randomizes between the other 4 at 20 min interval. At least this way I can get some periodic blast at constant speeds to turn up the stuff sitting in the sand bed. Also gain like a 10 watt increase over the max average draw of the wave mode that had the highest.

Hi I have just bought 2 Jecod mow 22 and unless im doing it wrong and its not working. We all no there is not a setting change for the random mode. However if you go to any of the others and set them to 30 and frequency 50 save it - then go back and enter the random programme it carries across the power and frequency settings and shows this on the display in the app and on the monitor - unless i am wrong

sorry you can set them to any lavel

Glad you figured it out. Yes they can be a bit tricky to work with the lack of quality instructions and a difficult app to uses. Will say when you set the one as a parent and the other as a child. The screen on the parent does not always match the setting for some reason in random mode. The main always goes f30 but the child will show f100 since I run my at max. But the main still is running at 100
