Vortech random modes and sync/anti-sync

[ScooterV]

This seems like it should be such a simple concept, but for some reason I'm not 100% sure I have it right.

I have an MP-60 on each end. If I set the left vortech to Reef Crest, and the right vortech to anti-sync, am I correct in thinking that when the left goes high the right will go low, and when left goes low the right will go high? So, the point of the tank where the flows meet will vary back and forth? Or, should I also alternate which is the master and slave for that to happen? Same with lagoon?

I'm also confused on "Anti-sync 100%". From reading I was under the impression sync and anti-sync sets a percentage of whatever the master is already at, so would never exceed that. Or, setting it at 50% it would always be half of the max the master would hit. I dropped the master (left side) to 20% reef crest and the right side still pumped away at a high rate while I assumed it also would be 20%. Hard to tell many times what they are doing though, putting a hand or ear on them sometimes I can tell. When set at max flow it's more obvious, but then I create a sand storm so looking to verify some of it rather than just cranking things up and down.

From what I understand (I run mine on Anti-sync), yes when one is on anti-sync it will run the exact opposite and your center flow point will move back and forth. Regarding the percentage of flow per pump, AFAIK those are independent and are not controlled by any sync or anti-sync. I run both of mine at 90, but when I drop one, it does not affect the other.

Run the master at what ever percentage and if using anti-sync/sync set the slave at 100%. The slave will run counter to the master at the matched speed. ie: I run my MP40 master at a max speed of 50% and the slave matches it at a max speed of 50% of what it is capable of doing. Yea it sounds confusing but it’s how they work. On anti-sync as one is ramping up, the other is ramping down. On Sync, they both ramp up and down at the same time.

Ok, thanks!! It seems I had it mostly right in my head anyway. Not sure why one on anti-sync was running so high when I dropped the master way down, but I also had some other issues that day from power outages so may have been an anomaly. I've tried the different modes but never got around to trying each and setting up a 24x7 schedule so I'll just get back to trying one at a time, slowly turn them up to find the max I can go without a sand storm, and make a schedule so I can say I have a schedule!! lol, hate to waste the Apex right, so need schedules!

If it helps here’s how I have mine running in master/slave anti-sync.

Master MP40wQD

Slave MP40wES

I'm using profiles so seeing it visually threw me for a second, lol. Question though. If your slave MP40 is anti-sync all the time then why have all the different times specified?

Otherwise, that's what I'm looking for. Well, I'll figure out which mode I want, and for how long, but just setting it now and then isn't working. Every time I made progress a Vortech went "missing" and I started over. With the Vortechs and entire Aquabus on a UPS now I never have one go missing, so it's past time to get them set up, lol.

If your slave MP40 is anti-sync all the time then why have all the different times specified?

I have no real idea. I just copied from someone else when I first started. I’m assuming the slave unit needs a mirrored time frame?

 

[ScooterV]

Ah, using the interface it may. I used profiles and one profile is just anti-sync.
