Hi guys, so my skimmer had veen doing great for a few days and it skimmed a lot. However, I turned it off 2 days ago and now when I just turned it back on the micro bubbles that were supposed to be produced by the skimmer disappeared and only a couple of large bubbles were formed. I took apart the whole thing and it was working just fine when I placed it into a new batch of salt water I mixed. The only thing I did during the few days was top the tank off with ro di water and that's it.
