they're awesome! swapped out a remora pro, so it's not really a fair comparison of before/after though.
get the quick disconnect option. i'm sooo glad i did. the sludge i have to clean out is too gross to make me unscrew the lid each time. i avoid maintenance now because it's pulling loads of crap out. IBS-quality skimmate. :barf:
alas, better out than in.
the other thing i really like is the modularity of the unit. the ability to expand the unit with another injector or lengthen the tower. really nice if i ever want to upgrade beyond what i currently have. someday. <sigh>
I really feel that the needlewheel skimmers are more efficient and effective than the beckett injector skimmers. Plus they are much easier to clean and maintain. I got tired of cleaning my beckett injectors that kept getting clogged when I had a myreef skimmer. For the same price you are paying for a Myreef and a pump you can get a nicer ASM skimmer. That is one thing that people don't always take into account is the fact that almost all needlewheel skimmer prices include the price of the pump and almost no beckett skimmer prices include the price of the pump.
I had an older MR-1. It was OK. It required constant adjusting. I ran mine with a mag-12.
I switched to an Euroreef ES5-2 and I pull double the amount of skimmate then I did with the MR-1.
The MR-1 seems well constructed and Andy (Maker) was responsive to emails to help me troubleshoot the skimmer. I just gave up on it and moved on.

After some thinking I found that I CAN fit an ASM G3. All I need to do is drain my sump and move it over. Then I have 8" clearance. How much room do they need to remove the collection cup? I have 25" clearance, which would leave me with 1.5" to remove the cup.
On the clearance you should be fine as Rob pointed out. I had a MR-2 with a mag-18 and was pleased with it. When I down graded tanks I whent with the ER 5-2 and I was amazed at the gunk it pulled out of a smaller tank. I would do the needle wheel before the becket agin. Nothing agains the becketts, just a preference.
