Hey guys here's my build of the UAS style scrubber.
I've acquired all the bits and pieces but haven't yet installed it, hopefully in the next few days i'll get it done.
This will replace my waterfall scrubber and be installed in the sump. I'm hoping to use air from my overflow instead of using an air pump.
Specs
Screen size, 5 x 4 (20"), single sided. About 3/4 cube per day.
Air bubbles fed from overflow pipe.
Led lights, 5 x 3W 660nm. Rated for 750ma, only supplying 650ma, measured the voltage drop and calculate about 7.5 watts of power.
Heres the LED's.
Bought all parts, including heatsink and driver from Satisled.com, cheap as chips, fast delivery to New Zealand, approx 7 days.
This T connector with slot cut will fit onto my overflow pipe.
Using these neat little gutter clips i found at a hardware store.
The clips are secured to the T using good old plastic ties, and allows easy removal of the screen, just slides on no probs.
Here's what it looks like with the screen attached.
The slot is wider than a normal water fall scrubber would use, and the screen is positioned higher than the slot, hopefully to prevent blockage.
The screen is positioned to one side of the slot so that all the bubbles rise on the lit side of the screen.
At this stage im not going to block the sides of the T connector, I'm hoping that i all the bubbles rise up through the slot and not out the sides.
If i can keep the sides open then that will add a measure of safety and prevent algae from blocking the pipe.
Will just have to try it and see.
I'm not using the screen as seen in the pics, in case you are wondering about not being rough enough
I'll be using a piece cut off from my water fall scrubber.
More pics coming soon once i get it installed.
