About 45 minutes of work this morning cleaning 2 of the Tunzes from my main tank. It's truly amazing how much loss in flow there is as they get dirty. Forgot to mention the added saga yesterday as the skimmer wasn't working when I went to check on it before cleaning it. Seems a piece of salt creep broke free from the outside of the venturi air intake and blocked the airflow so no bubbles. Don't know how long it was like that, but it seemed to me that the water had gotten slightly greenish with excess algae. Now 24 hours later everything is crystal clear again. Such a delicate balance we keep.
