Jon, I have a modified MR3, thats so big a Mak 4 does not do it justice. I started on modifications this morning, to the inside feed pipe from the injector. Hoping that making it similar to yours, running up into the skimmer, will get the desired results from the Mak 4.
I had to run the water level to high before, and could not get the body to fill with white out type bubble like yours or like my 28in. Saltwater Connection beckett.
Did you not put a 45 degree on the top, to achieve some swirling motion for a reason? Here is the original pic of mine. I will have another of it after the mods. I guess its now called a modified MR3-Jon beckett skimmer.
