New impeller
I purchased a new Penguin yesterday and what a difference!! I thought the new impeller was going to suck the plants out of the gravel. After looking at the old one again, I still do not see anything wrong with it, other than a thin coating of slime. The lfs guy said he would look at it and order a new one if need be. I think the slowing down of the biowheel was an indication of the impeller’s lack of suction - even though ML and others said a slow biowheel is nothing to be concerned about. Barbara
