Hello!
I have an new idea for feeding the algaescreen with water flow and air, i have thinking of this for a while and have now run some tests with my prototype unit. The unit is not tested for how it will be growing algae, just for water flow and air hudraulics. The tests is looking very good and i have hope for this design.
This prototype scrubber is not an UAS, but it is an DAS (downflow algae scrubber) with GAC option, if this works as i hope it could possibly be a good filter as algae scrubber and GAC filtration if wanted. The prototype scrubber is siply hung on the glass of the tank, scrubber unit inside tank and light unit outside the tank.
My main goal with this new idea is to get rid of the air pump, so of course this prototype do not use any air pump to feed the screen with air
The prototype is an HOG version, but this way to feed screen with water flow and air can probably be used in on top of tank scrubbers, in sump scrubbers, on top of sump scrubbers and of cause in tank scrubbers.
I will post some videos of the prototype running later this weekend, but here is some pictures of the unit:
The scrubber consists of three main parts, on the picture the inside tank unit to the left, and light unit to the right, and spraybar in the middle. As you see the both units uses reflectors to get the most out of the lightning.
This picture shows the in tank unit ready mounted with spray bar, filter pads and you can see the small powerhead that is used for the test:
On this picture you can see the inside unit running, no screen is placed inside the unit, this test is just for looking at water flow and air:
Hope this idea works, and that you like it.
