thanks rgibson...well it sounds like this mod should work great on a newly acquired mr-2 with the second injector...it came with a gen-x pc-55hp,but i thought that might not be enough pressure for 2 injectors....so this trick should work good for me....

AND I think the jury is still out on re-drilling the beckett head, OR if you do re-drill it please set up an accurate base test and share the results with us.

I've been tagging along with this and it looks great, anyone try it with a dual beckett yet?

im about to....but i want to clean everything up and put valves on each of the injectors.....and run for a few weeks as a baseline...

This is a great thread. I just bought my first tank and skimmer, the tank is a 120 and the skimmer is a 5220 Barr Aquatic dual beckett. Simply, the skimmer seems a bit large, but I'm wondering if this mod will make it seem juuuuust right. I guess I'll have to wait and see. Has anyone using this mod actually been able to scale down from one pump to another as a result?

Ok I've read the entire thread.
This sounds great and I'm going to try with some of my spare becketts. My question is about hole height. should they be in a straight ring aroung the beckett at the same height as the top of the stock holes? Does that make sence? I'm running a PM bullet XL with a Blueline 70, has anyone done this to the same skimmer. If so how many holes and what size worked best? Kedd |

You have the hole pattern right,try 22 holes to start with.

this may be a stupid question, but does the injector need to be installed vertical ? or will it work horizontal ??

The water that tends to pool in the beckett housing might be a concern but it also tends to re-injects itself via the holes in the beckett. This setup would be easy to test, just use a hose on a spare beckett and set it up so you can observe the action. I'd like to see if this works. Please post some pics if you decide to try it.

I am setting up a 180, and plumbing in a beckett II clone, but it would be way easier if I could install in injector horizontal, but want to make sure it would still work

I don't think it will work because of the water pooling at the bottom, which would cover half of the holes. Does that make sense? HTH |

Whiteice 669 how high up is the beckett on your skimmer?

The most accurate way to test this, I think, would be to run two identical systems simultaneously. One with the stock Beckett and the other with Waylander's mod. This should be the only difference. In reality the test should be conducted several times with different pressure rated pumps. The flaw in running the system for a while to get a baseline first is that the assumption is that nothing changes in your system may be incorrect. Spawning events, different feeding schedules and products, different evap rates, death of something you cant see like a sponge under some live rock somewhere) Coral splitting, macroalgae cycles, varying water change schedules. There are a lot of things that can change from one day to the next that will effect skimate production and bubble generation. The only way to eliminate all these variables is to run the tests at the same time on the same water. Even if you are running two successive tests, it is difficult not to get your hands and arms in the water when performing the switch between the beckets. The oils from your skin will effect skimmer operational performance which makes it difficult if no impossible to compare the before and after. The results will be skewed. I realize this is both cost and sometimes space prohibitive, but it would be nice if someone has the resources to do this kind of test to look at results. I don't have the space for two skimmers besides the fact the my skimmer pump is set up very uniquely and can't be duplicated. Nor do I own several pairs of identical pumps. Anyone care to comment on how to setup the ideal test. Anyone else have enough equipment laying around and the space (and time) to run a test or two? Just my $0.02

what do you mean how high? overall height? or injector height

How high is the beckett from the bottom of the skimmer?

Can't prove anything since I have no way to test but I moded my 30in Aerofoamer. It is 8in diameter x 10in tall main tube going into a 4in diameter x 10in tall top tube going into the collection cup. It has one beckett driven by an Iwaki MD 55 RLT. I drilled approximatly 20, 1/16th holes. I couldn't get any skimmate unless I ran the water level up to about 2 in from the top.
Now I get lots of dark skimmate running water level about 6 in from the top. Does this make any sense? |

gary faulkner did you fill in the four holes that were in the beckett?

Oh yea, and its 34 holes, not 20.
I just counted them again, when I cleaned the injector. Like I said, I can't prove anything but without this mod, I got very little skimmate. Thanks Waylander for the great Idea. Might not work as well with a smaller or weaker pump, but with my set-up, it really rocks. |

there is 4 inch's between my base and the bottom of the injector

4ft 8 inch dia running single beckett on Panworld 150ps with mini hole mods plus one of my own. after body cone reduces back pressure stagnation on the back of the ball (in theory). should improve suction.
Picture is with 12 3/32" holes. I added another 10 3/64" holes since then. running one week now. |

salt lick if you had a Dwyer air gage you could tell how much more air your beckett is pulling in.On my beckett skimmer i get 26 SCFH of air in put.I think you have a good idea about the cone could you tell how you built it.

So what are you all using to plug the holes? Looks like thickened epoxy?
Great idea salt lick!
