I removed the chaeto from that portion of the system about two weeks ago, primarily to see how well the ABS performs on it’s own. Nitrate and phosphate did increase some. Nitrate is usually between 1 and 2 ppm. Phosphate is around 0.12 ppm.

I feel like the system is cycling well when it processes batches about twice an hour.

I was really impressed with how quickly pods populated the remote deep sand bed. I noticed them there within a day of turning the system on and they seemed to have reached a saturation point within a few weeks. I wish I could figure out a way to flush some of them back into the tank on a regular basis.

I went through a roll of felt, somewhat prematurely, because the float switch stuck on for about an hour and a half recently. I added some code to prevent that from happening again but the usage is even faster than I had calculated and would probably have only lasted me about 50 days.

Biomass still builds quickly in the inlet side of the reactor; much more quickly than in the reaction area, much to my dismay. The mass primarily builds near the output of the process pump, where the organic carbon rich water meets the higher oxygen levels. I continue to have to manually clear the inlet area to the distribution pipe a couple of times a week.
