I bought one of these, and my algae looks black like the LED is burning the algae. The air tube only let's bubbles out of one hole, but I keep the flow up. Not sure what to do. I'm thinking of taking 5 air tubes link them into a manifold and let 5 tubes coming from one source power this thing.
Black means that there is not enough light, or not enough hours, for how high the nutrients are in the water. Run it at 22 hours for now.
Clean every bit of the black off, including in the holes in the screen.
Tuck in the tube segment that is flowing, and un-tuck the non-flowing ones. Also tilt the whole unit one way or the other. A larger air pump like the Fusion 700 would solve it too.

Welcome.
Look in the Upflow Algae Scrubber pictures section.

Been lurking here on and off for a while with a plan of some day making an ATS. Until now they have not really fitted my setup.
However the SURF2 concept seem like it would work great.
I have a couple of questions regarding the construction.
The silicone used in the LED part. Is it the same type silicone as used when gluing a glass tank or is it liquid silicon that is poured in?
The nylon strands used to built the "tepee" where are they from? I was first thinking that it was the same type of strand used in a grass trimmer (at least in my part of the world) but these seem softer.
[EDIT] Never mind the question on the strands. I found a close up that showed them better. Now I know exactly what they are.
Welcome.
The silicone can be whichever you can work with best. We use the pour-in type, but it can be hard to work with if you are not used to it.
