Hey, I did this mod on my 3 new 1200's today and I am very impressed. I got them yesterday, and I was a little hesitant to cut up a brand new powerhead, but I'm glad I did. I took some pictures to document the process:
First, the maxijet in my tank.
The dispersion piece removed (just pulls off):
A picture showing where I cut and what I used.
I thought it was going to need some sanding, but I later rinsed it off and it didnt need any.
Mounted back in my tank... after I tested this one out I did it to the other two. The flow from this one switches from blowing slightly against the glass to halfway towards the other powerhead.
I'm bought
this package from Drs. Foster and Smith, and after doing the mod I am VERY happy with the flow in my 75 gallon tank. I was planning on getting another one of these kits with a few 600's, but I really dont think it's nessecary after doing this mod. Even with the wavemaker, the flow is not truly random unless you do this mod. I am extremely pleased...
dont expect it to spread out the flow much though, I will still need to move these things farther away from the rockwork when my frags grow out. I showed my dad and he freaked out: "WHY'D YOU BREAK THOSE NEW THINGS?!" Oh well, I'm the reefkeeper, I know best

.One question though: how is this piece supposed to fit over the edge of the aquarium?
Not even close!:lol:
