    I adjusted/moved my wavemakers as I was getting bald spots on the bottom of my tank from sand being blown away. Can’t seem to get decent flow throughout the tank now. For those with a 6ft tank, what are you using for flow?

    I have a MP40 at each end and and an angled powerhead on the back. Seems to be ok.

    I run two MP60 one on the left top corner and the right corner (about 8 inches in from the front glass and 8 inches down from the water line) and a MP40 back right corner. I run the MP40 at about 80% and the MP60 at about 50%. To help stop sand from blowing away you need to place small rocks in the highest flow spots in the substrate to help force the flow up and over the substrate and not blast on it. Sometimes you need a few.

    i use 2 MP40s one on each side of the tank and run them at 100%. I also use a CP40 at full speed to provide flow at the back of my live rocks to avoid detritus settling in....

    All you people with your fancy, expensive MP40s! Guess my sunsun and cp40 aren’t enough. @TheGreenStag is your cp40 on the back wall? Horizontal or vertical?

    tunze wavebox here. Along with central returns seems to keep water moving.

    they are working great.
    With 2 of them them very easy to reduce the flow if too much.
    One is not enough.

    I think i’ll just add another one. I hate having them visible on the sides, but guess there’s no way around it.
