Here is a couple of quick pictures of the drum installed in the pallet tank.
It was installed in a very very dirty tank, and i didnt do any cleaning whatsoever, which is why it looks pretty dirty after running 14 days. however the drum itself looks fine as new, this is the new 125 micron screen installed, but the 300 micron looked just as fine.
I will clean the filter tanks one of these days so i can pictuere the water before and after the drum.
One of the adjustments i have to do it raise the spray bar, its missing 10mm of the screen in the middle, and i dont want to install 3 spray heads, as that will just result in more water usage, so by raising them 5-10mm it should solve that problem.
and then im designing a new connection entry for the waste tray, so that you will be able to get your hand into the waste tray, and remove string algae if needed.
Also in the long run, a protection screen will be needed for the gear, so you cant get your fingers stuck if it starts running, i will take better pictures of the gearing later on.

Oh yea, and the spray bar just runs off the tap water, through a electric valve which is controlled by the arduino.
However, a pump could be used, and eventually i will problaly make a "mini" sieve, with a 30 micron screen, which will sort out the waste from the waste water, and then pump the clean water back into the pond, so you reuse the water.
