BM Nano Skimmer comes to Canada

DiverDude · #1 05-09-2010, 03:10 AM

The valve I'm talking about comes with the Maxijet 1200 that runs the skimmer. Each Maxijet comes with a bag of goodies (mounting brackets, intake covers etc. and it was in there.) I got the skimmer (new) from a fellow CanReefer who had bought 2 end ended up only needing one. It was he that told me to use the valve.

After I posted this morning, I watched a number of videos on this skimmer and noticed that they were all mounted higher out of the water than mine (the bottom of my collection cup is perhaps 2.5" above the water line) and I thought that the water pressure may be causing this so I planned to try moving it up a bit tonight. Lo and behold, that's exactly what you're suggesting !

The irony ? When I got home, it seemed to be skimming quite well ! The upside to the way I have it now (with the valve) is that it's a LOT quieter -not that this is an exceptionally noisy unit.

I'll fiddle a bit with the height and try with/without the valve and see how it goes.

Hi

Glad my support helped. but the valve is NOT part of the BMQQ-2 parts assembly and looking at all BMQQ-1 also there is no valve, I have never heard of the BM-QQ having its inlet air intake restricted this can cause all manner of issues.

So I contacted BM, and no a valve has never been part of the kit, what they think has happened is that a worker left the maxi jet venturi valve that comes with all maxijet pumps in the kit by mistake. I have checked all 23 units here and not one has this valve, so please do not use it. It is not mentioned in the kit list either.

I am glad you are getting it dialed in

I can't be sure because I have 4 Maxijet 1200's around here so it's possible i pulled the valve from a different box but the point is that when you buy a maxijet, it comes with a bag of bits and the valve is one of them.

One thing for sure is that running the skimmer without the valve does not work. I can't lift the skimmer any higher because the maxijet comes out of the water and interferes with other equipment which means the valve is my only means of controlling this.

I'm really looking forward to the day when I have a proper setup with a sump under the tank and the skimmer will go in there !

Hi

So it sounds like the skimmer cant run as designed due to other equipment locations restricting its adjustment, in this case I am not sure what advise i can give

The only thing i can say is your not giving the unit long enough to bed in, a skimmer takes up to a week to mature, let is run wet, allow it to get gunky then it will stat to settle in

how will this unit run on a 65gl set-up? I was going to get one for the 25gl tall... but I want to be able to move it up to a 65gl eventually!

Would this fit on a red sea max

On very low bio loading yes, but leaves no room for expansion.

I am running a BM150pro on my 60 gallon.

how much does that go for and is it hob?

I frigg'd with it more last night and managed to get it so that the top of the maxijet is at the water surface. I can't lift it any higher because the maxijet hits the plastic screw that holds the skimmer body in place. Besides, the Maxijet is supposed to be run fully submersed for cooling, no ?

It is now running unthrottled (air hose direct to the cup) and while my wife doesn't like the louder operation, it's running without overflowing now. The skimmate is still wetter than it should be though.

The skimmer has been running for nearly 2 weeks now.

I watched all the YouTube vids I could again last night and I can't understand why all the installations appear to be so high (collection cup height above water). I even saw one guy running the maxijet half out of the water ! From what I can see, the top of the bubbles should be around the bottom of the collection cup wheras mine are about halfway up the cup. Obviously, this is why it's skimming wet.
