Having microbubble issues with deltec MCE600 skimmer

[imisky]

i actually get the best performance to microbubble ratio when my valve is 100% open. i get a full cup of dark brown skimmate + sludge. but there is a breakin period for the mce600 give or take 2 weeks for me to fully get rid of my microbubbles. the only bubbles i get now are from the fall as i dont use the plate.
