MP40s - what setting do you prefer?

[Coralgurl]

I've had mine running on tidal swell for a while, wondering what settings you prefer, just switched mine to reef (yellow).

i use reef crest on both mine @ 100%. nutrient export for a day b4 waterchanges.

I have 4 pumps. All running different modes at 100%.

Gives me nice random flow

I run the yellow one

TSM for me. I have 3 pumps, one on each end & one at the back. Every so often I'll do the NTM to shake things up. The back one is speed limited to about 35% since my tank is relatively narrow & if that one were to slave along to a higher speed with the other two, it would be too much flow back to front at some point during the TSM cycle. I had intended to buy an MP10 for the back, but the speed limited 40 works very well thanks to the many options available with the W ES controllers.

Does anyone run them master/slave or all independent? Markod has already answered this, anyone else? I initially set mine up to try for the waves but it didn't seem to work. I have 2 on my 180 running at 100% think I need another on the back. I have an MP10 on my 55 and it picked up the programming, even though it's in another room, also programmed to my lights, this runs all 3 in night mode until 11 am-9 pm.

Mine are in a Master/Slave grouping, but as mentioned, the one on the back is speed limited. 180 is a big tank to get a wave with two MP40s, although you should get at least a small one going. What length is the tank? Mine is 4 ft & no trouble getting a good wave going. There is a good explanation in the manual about letting the controllers 'auto' tune a wave for you. You just need to set them up master/slave with the slave anti-synch and keep an eye on the water surface as the auto tune feature changes speed & ramp up frequency. Once you see the wave start, all you need to do is hit the Set button (I think) & the controllers will memorize that setting. After that, any time you want a wave, you simply need to choose the pulse mode & the pumps should remember the 'wave'.

I never did get a wave going, but I don't think I had them correctly programmed. The tank is 6'x2'x2'. I started the tank with 1 mp40 and that was definitely not enough to push flow to the other side of the tank, so added another. Will leave them on reef crest for now until I can pick up at least one more.
