Thanks. If growth continues like that I'll start testing from next week. It's already much darker and thicker than the previous pic.
Been running for almost a week. Quick pic: [IMG]
Looking good!
It's a shame, I prefer the look of it in white. I thought it may also help reflect some light back onto the screen, as opposed to having a black...
Update - version four up and running as of today. Edge around the face of the screen to minimized light leakage. (More on this below) Scrubber...
Tis, but version 4 will use nylon mesh around the cylinder, to rule out any issues with growth on the 3d printed material.
12th week update: Nitrate: 40ppm Phosphate: 1.04ppm Took the scrubber offline yesterday. Revision 4 will be up and running soon so will start...
11th week update: Nitrate: 10ppm Phosphate: 0.86ppm Again not much to report.

10th week update: Nitrate: 5ppm Phosphate: 1.21ppm Not much to report. Screen is still pretty much bare after it was cleaned a few days ago.
Update. Screen growing lots of green algae, but it seems to be turning white. The intensity was set to 60% and the duration was 12 hours. I...
Ninth week update: Nitrate: 20ppm Phosphate: 0.60ppm GHA growth now appearing on the scrubber, with more green growth each day. I think all the...
You could always just sell it and build or buy a waterfall scrubber. I doubt you'd have any issues growing algae then.
I feel your pain :eek:. What is it, almost two years with the SURF2 and no real decent growth?
Eighth week update: Nitrate: 5ppm Phosphate: 0.04ppm Was still getting diatoms growing on the screen with the phosphates at 0.56ppm, so I...
Seventh Week Update: Nitrate: 10ppm Phosphate: 0.91ppm Still getting diatoms all over the screen. It's getting pretty annoying now. I purposely...
That makes sense. I initially had the LEDs on for 12 hrs/day, then over enthusiastically raised them to 18hrs/day, which I've since knocked back...
Sixth week update: Nitrate: 0ppm Phosphate: 1.13ppm Still plenty of diatoms growing on screen, but it feels like that is starting to wind down...
Had a look at the scrubber today. More diatoms growing on the screen, but also quite a bit of white stringy algae, a few mm long. Pretty odd,...
I did actually plan on making the fins curved which will give it more torque, but to be honest, there's a tonne of torque on this thing already. I...
