bro, like what bro hammy mention, my camera is unable to capture a clear picture of the bubble size. Think you have to come my place and give a verdict yourself.
The Deltec might not have kick in completely. Let's wait another couple of weeks for the experiment.
Btw: Any Deltec users can comment if Aquabee 2000 is too strong as a feeding pump for Deltec 851?
Upgrading is not sianz... but very expensive. . every skimmer lugi a few hundred. . so far i tried mazzei, beckett, venturi, fleecewheel and needlewheel.
Brands wld be weipro, macro, Reef maniacs beckett, Schuran jetskim 150, Bio Ocean's mazzei, Ati Bubble master fleecewheel, Deltec needlewheel.
I always believe that everyone's opinion differs and the best is to judge the skimmer yourself instead of relying on all those product reviews. Although the product reviews does hold some truth, but nowadays its just plain advertisement.
