Happy to hear the resutls. The red is probably cyano which is always the last to go.

From new to green in 3 cleanings (and just 2 LEDs)...

All of our new units, except the lower power ones, will now come with a black cloth to cover the LEDs for the first week or two. Because the all-white interior of the units reflects so much light, when it is new the light levels are way above the highest amount that can grow anything. Once growth starts, the white is covered with growth and the total light levels drop, and the cloth can be removed.
This covering of the lights can be done by anyone, on any scrubber, even waterfalls. Waterfalls used plastic canvas which had more holes than material, and they were not in white compartments, so the light levels when new were not that high. But it still might help if a new screen stays completely empty.
The reason for a white texture and strings, of course, is too allow more light to reach the base of the growth that does the attaching. As the growth gets thicker, the bottom layers will almost be in darkness, so the white surface doubles the light there by reflecting instead of absorbing the light.
Nathan P. says this is just one week after his first HOG3 cleaning:
First video to show LED shade cloth installation:
"And this is about 2 weeks growth, compartment completely full, nitrates are at 0, phosphates are between 0 and .25 per API, top layer was touching glass and was really yellow, when I pulled the layer off there was a ton of algae and it was dark green" -- Nathan P.

After three more months of filtering, and ten more harvests, did the extra high output air pump help the SURF4 ?
