What's the general consensus for the best red/blue LED ratio? I often see a range from 4:1 to 8:1. The 7:1 ratio was the best ratio done by NASA...
I guess that makes sense. Air bubbles in the HOG style travel the full length of the screen because they are mounted vertically. Since the SURF...
Though the 3x won't actually remove 3 cubes per day. It is lame. I don't really care except for the fact that there's a lot of people buying his...
Yep, I'm now banned.
Do you have any updates to this Kerry? I think it's definitely something worth exploring further. I wonder if having all three (660nm, 445nm &...
Now that I have my 3d printer up and running I can make some 3d printed screens. On my algae scrubber I found that algae became established...
I think he does include them now, I watched one of his more recent videos a while ago and he had included it. I would have thought he could come...
In the video he says that he was told by the folks at SM filtration to up the hours from 20 to 22 per day. Seriously, like that is going to make...
Oh, well pretty useless then if you can't get water flow through it. Maybe there's something we're missing or can't see.
I reckon that ebay one ain't too bad. I'm only looking at it on my phone, but it looks like a submerged scrubber? Rough up the screen and put a...
Hmmm. Well that's good news. As long as he doesn't try to split the patent into two and resubmit them.
Update: Water got in to the LED housing a couple of days ago and some LED's got fried due to a dodgy silicone seal. If the acrylic screen was just...
Will be adding a blue LED when I get a new soldering iron, my old one's crapped out. :)
Looks pretty sweet
I keep tinkering with this and have set up a semi accurate day / night cyle. The LED's now come on very dimly at 7am, and slowly ramp up to full...
Five days later and the algae is definitely getting thicker. The middle is starting to fill in, so I've cranked up the LED's again. Looking good...
In the sizing guidelines SM pretty much sums up how flawed the UAS/SURF scrubbers are. They are here:...
Ten days later it looks like it's taking off. While it's a bit hard to see in the photo, there is decent growth around the edges, but a definite...
This is completely ridiculous.
From what I can gather from that, he wants to patent using a colour sensor to determine the amount of algae growth, and set the light level...
