Know what you mean, they are quite pricey and I am not totally sold on them yet. I have 2 mp40w es right now, but have opted to use 4 tunze wave boxes in my new build, I know they are quiet and bought all 4 used with a 7095 controller for about 800 total. I will try the tunze first, but may go to the vortech's down the road.

Great timing!!!

I have a 300g (6ft) in the wall tank for a mixed reef and I just purchased 2 MP40's. My tank's been cycled for a while but just firing it back up. Assuming that I have 2 towers of live rock spaced away from the back wall, what are your thoughts on best placement of these 2 MP40's and the modes plus I have up to 4 additional powerheads?

Someone suggested to place one at each end and face them against each other to give a random current and a different person suggested against it because they counteract each other therefore not maximizing the flow. Your thoughts?

Thanks

Download the manual, it will give you an idea for placement and options. With the pumps at opposite ends, you can achieve a few different things, but again, depends on what effects your after.

just ordered a second MP40... I'll try and slave them all together and see how it goes.

I shouldn't be getting this excited about water pump. I really shouldn't.

I have the 2 60's opposite sides of the tank on opposite corners. I am having a few issues with the pump and having difficulty getting service. I think the next pumps i buy will be tunze also.

Options for configuration with mulitiple VorTechs is almost limitless. Your wallet is the limiting factor I reckon. Number of slaves as already mentioned is unlimited. You can also build separate master/slave groups on the same system. Some folks even run them all randomly on their own schedule for some really chaotic results.

Surprised to hear there are issues with the MP60s. As far as service is concerned, IME EcoTech is generally very responsive and forthcoming.

I've been looking at videos of what these puppies can do on pulse mode. My tank water level is full to the rim when the return pump is running so I don't think I'll ever be able to use those modes, but this will give me 2 MP40s and 1 MP 10 on my system. I'm going to put the MP40s opposite each other and the MP10 on the back wall and play around with things and see what I can achieve in terms of flow patterns.

Nutrient export mode looks interesting, but if it makes to much of a wave there's going to be water all over the floor...
