I was wondering when or if you would notice that. I was going to ask but then I thought I would just wait. This where the difference between the needle wheel skimmer and a Venturi, Beckett, Aqua C skimmer comes into play. A needle wheel just like they advertise, create tones of tinny bubbles that are in uniform in size and do a great job on removing organics but the other skimmers mentioned will create multi size bubbles, from tinny to large or should say lager and these bubbles do a great job at removing particulate's tinny, tinny floaties in the water, so they should be called water strippers as I believe that's where the technology came from, water purification plants. The Beckett and Aqau C spray system are probably the best at it, and this is where the whole thing of over skimming came from because if you too over sized with Beckett skimmer you where scratching your head on why your corals did not look to good, because it was literally stripping the water. You see you take out some of the good stuff too, I don't know if anyone on hear remembers a Skimmer called the AreoFoamer. It was a Beckett style and was tested by a gentleman named Bob Goemens, a famous Reef Guru at the time, I don't think I have the last name correct but he found it to be the only skimmer that he ever tested that lowered his Phosphate levels in his tank and his tank became almost crystal clear. Pit Fall was they need a BIG pump which meant much higher consumption of Electricty and you will have to feed Corals no question and clean the neck like daily, because if you did not skimmer would just not work properly.
Sewerat just a little tip when or if you feed your Corals shut the Skimmer off because it will definitely suck the food out and leave it off for like 1 to 3 hours when you do.
Anyhow enough with the blast from the past, enjoy the new skimmer and the learning curve and let us know of any other little things you notice like polyps closing more or opening more and also keep a eye on any 100% filter feeders and Clams if you have.
