One last try with this skimmer. I turned it 180 degrees so that instead of emptying into chamber 3 it empties into chamber 1. This is an AIO tank with overflows in chambers 1 and 3 and the return pump in chamber 4.

Now the water exiting the skimmer has twice as far to travel before endng up back in the display. We will see how this works since now 1/2 of the water it is skimming is previously skimmed.

This would be a similar effect to some of the nano skimmers which appear to have their intakes and exits either in the same chamber or right beside each other.

This skimmer has always produced a reasonable quantity of skimate it has just been madening with the micro bubbles.
