Normal chores in the GreenHab were performed on each of these occasions.

Water level in the GreenHab was again about 5 inches below normal with no flow from Tank #4 to Tank #5. At 13:30 hours there was a flow of 3-4 drips every second. By 20:00 hours level was back to normal with a flow of 1 drip every 15 seconds.

Both aerators are working, one is in Tank #2 and one in Tank #4. These were cleaned today, improving their flow.

There were minimal Suds in Tank #2.

All plants were sprayed with water on each visit and have been fed today.

The sump pump is connected to a timer which activates the system at 12:00 hours and 00:00 hours.

The TST tank is still being filled as required by the pump.

Water level in the plant buckets is about 3cm from the top.

The trickling filter 2 hose, which is supposed to allow water to trickle from holes into the filter tank 2 above it has been the cause of water loss onto the floor of the GreenHab. Following advice from Gary Fisher I have disconnected this pipe and examined it. I found that only two holes were still functioning due to plant material having clogged the other holes. This was causing a higher pressure ejection of water than should have been through these holes, pushing the water over the edge of the tank. I have scrubbed this pipe and cleared every hole. I have reconnected the pipe which is now functioning properly and there should be no more water loss from this for some time.

I have checked filter tank 1 which has plastic piping instead of hose, and it seems to be functioning fine.

Due to the invaluable help that I have received from Gary Fisher I have sent an e-mail to him to clarify the other problems I found at the beginning of my rotation.

I have yet to forward the data logger spreadsheet as requested.
