Flow Question for 650G Reef

[DanCorals]

Hey everyone, I am attempting to get a strong random flow for my 650G reef tank which is 130'' x 36'' x 32'' using 4 Vortech MP40s. I have tried a number of configurations with single vortechs in each quadant and even multiple vortechs on a wall running at 100%.. In each case I only get water movement for the first 24'' and the water at the center of the tank is not really moving. I "Think" installing MP60's instead might be an option but I am nervous to spend the cash and just have the same problem. Is anyone using an MP60 on a long tank? How far can an MP60 push water?? Also, is there a different configuration for the MP40's that might get better water flow down the tank? I am not doing any wave motion because I dont want to stress the tank...so I am using either constant 100%..or Reef Crest Mode.

Thanks!!

MP40 is way to small for that set up. how thick is the glass?

I have both 60 and 40 ... flow of 40 gets to 30" , flow of MP60 gets to about 4.5 foot.

Id go with 4 MP 60 and some MP40s on back in that tank if you are thinking SPS.

You could sell your 40s and go with a Hydro Wizard $ 1,700.00 shipped to your door flow would no longer be a problem

Dan,

Here is a link to our flow calculator, it can help you determine which Vortech pumps and how many will be best for your aquarium: http://ecotechmarine.com/calculator/

Thanks everyone for the quick replies. The tank is actually viewable from bothe sides so I can only put the pumps at the edges...so that creates a problem with having to push water all the way across the tank from both sides. I ran the ecotech flow calculator a while back and based on that, if I added only one MP60 to the setup I could be in the right range...but given the length of the tank I dont think thats accurate. I guess I will have to shell out for an MP60 and do a test. If it really reaches 4.5 feet then it might be just enough to have them on each edge along with the MP40s. Thanks for the feedback!!!

The mp60 at its lowest moves as much water as a 40 at its highest

put one MP 60 on each end in anti sync mode and I think it might be ok
