When I first began using the pellets the skimmer began to pull darker skimmate after 3 to 4 days. After about a week I noticed the skimmate increasing in volume. Very nice. I'm happy.
Now, after 5 months of use I'm noticing the skimmate changing. It is now a lighter colour and the thick skimmate collecting on the walls of the collection cup and neck are almost of a "chunky" texture with two different shades of brown. The chunks are a lighter brown than the more normal paste-like stuff. It is unlike any other skimmate I've seen. I just cleaned the skimmer tonight but will post some pics of this strange skimmate in a few days.
Anybody else notice a change in the skimmate after several months of pellet use? And if so what does it mean? There is no change in the levels of nitrates and phosphates.
