How do you get the MR2 skimmer tuned in? Everytime I think I got it, it either over flows or the bubble are too low. I am running an Iwaki 55 pump on it. How low should the bubbles be? Is there certain setup I should take to get it tuned in? I took out the cotton should I use it?
it takes a while for the skimmer to get broken in and for you to figure out how to work it. i hate to say read this thread, but "read this thread". there's a lot of good information in it. andy is very helpful at MRC, you can send him mail and he will respond.
whenever i fire up my skimmer after cleaning it, i have the air valve turned off all the way. i have the water level set just below the becket, imagine the dongle thing inside floating in the air, below that. after the water level settles in and i know the water output valve doesn't need adjustment, i turn on the air, a half turn. wait a while (like 15 minutes), then another half turn. for my system it typically starts making a useful foam around a turn and a half to a turn and three quarters. when the skimmer is clean and the sludge tube is not blocked, there's about 1/2 turn of air adjustment i can make after it starts making useful foam.
starting off with no air after each cleaning, getting the water level stable just below the injector, and slowly turning the air up was the advice from this thread that helped me the most.
this is just my experience. there is a lot more captured in this thread, you need to figure out how your skimmer is going to work on your system with your maintenance routines, physical setup, pump, sludge collection system, etc. you also need to learn how it reacts to things like feeding your fish, putting your hands in the tank, stirring up the sand, using epoxy.
i use the cotton, and put a fresh ball in each week when i clean the skimmer.
