System Start-up going slowly but progressing.

Good questions, David. I think I'd be inclined to just let it keep going as is for a while longer, and wait to see if it clears up as the sludge blanket grows and biological populations mature. Yes figured as much. Assuming that the solids in the 3rd tank are settleable -- i.e. not in colloidal sus...

System Ramp up progress

I was inspecting the progress of our bio-filter system and its operational progress today. I have noted the following things, because I had no "active sludge layer" at all to start off with in the anaerobic (2)tank the water passed a lot of "ultra fine solids" to the aerobic tank in the beginning, t...

Areobic chamber

So the water is taken from between these lines near the top of the tank. I suppose you could, but I don't think it would be a very good substitute. It would be much heavier, provide a lot less surface area/volume, and be harder to maintain/clean. Better to just roll up more furnace filter material -...

BioFilter Treatment Questions

1. Where is the water taken from in the last stage?

2. Is it worth installing a protein skimmer component?

3. Since I'm having trouble finding the geo-fabric you show in the system
could I instead use 4-6mm washed river stones?
