Hi andez! before when I started i use the same skimmer you have. Apparently, you have to wait for a quite few weeks before this skimmer finished the break-in period. Mine before took about a month before the microbubbles was resolved. In the overflow issues, that is the main concern of that skimmer, since the cup is too small and if your air inlet is too strong, the water together with the skimmed bubbles will overflow, so you better watch out on this most of the time. If you are very consistent in changing water 10-20 times weekly, think should be ok as long as you maintain your water quality. But still, it's advisable if you can invest on a good protein skimmer. I think you can look through the forums on which brand is best for your tank. Enjoy Reefing!!!
