Sherri,
I was using that EV90 with a tank full of triggers, wrasses, hawkfish, maroon clown, and a few other very messy fish in a 135.
We were definitely underskimming (according to specs) the 135 with the EV90 but it NEVER failed to keep the garbage out of the water and seldom even needed to be cleaned. This MR2 requires disassembly every 1-2 weeks. I have already taken the skimmer apart for cleaning in the past 7-8 months well more than in 3 years with the EV90.
AquaC makes a fantastic product. Fear not- your bubbles will very likely take care of themselves after another week or two.
