Pumping down the south filter. Discovered there was no barrier to hold the sand.	Because we were trying to figure out what to make the barrier and ramp out of, we left the filter sitting too long & had to remove this layer of sludge before I could run my machine.	Cleaning off the layer of sludge apx. 1 in. thick @ the most.	Filling the filter w/ water so I could run my machine.
Machine running	South filter after the machine ran	Same as before ~ Alternate view Sludge was apx. 1 to 3 in. deep	North filter prior to cleaning
Washing duckweed & sludge off the rock after the machine has been ran.	Pushing sludge towards 6 in. pump	Cleaning sludge off the bottom, pumping out w/ 6 in. trash pump.
