Hi Folks,

time to show my first steps with a "test scrubber". If all goes right I will install a similar Scrubber in the sump of the tank. First a few pictures of the construction of my Scrubber.

Pictures from day 3:

5141

I couldn't find a > 20W CFL so I ended upwith a 13W plant grow CFL (purple color, seems to work)

Pictures from day 6 and 8:
5142 (day 6)
5143 (day 8)
5144

I use a spotlight (see reflector in picture above) for applying the light of the CFL.

I think I can harvest in a few days.

Kind regards

Wow, this looks great! I'm glad to know that the 13W CFL for plants works well. This is the kind I plan on using if I ever get to build a scrubber of my own. Thanks for sharing the pictures.

Hello SantaMonica,

it's a Saltwater Tank, but a cold one (temperate). Residents are from the mediterranien sea, the north sea and baltic sea - self collected. Mostly Anemones and Shrimps, only 2 Fishes, 2 sea urchins and a black brittle star.

Update: Time for harvesting!

Although the 13W CFL is much to less - according the Algae Scrubber Basics - it seems to work great with a plant lamp. It has its peaks at 660 nm and 450 nm. Here are the pics from harvesting:

Great ulva lactuca growth :)

Yours is a good example of how even-flow is not required across the screen, because the thick growth will re-route the flow anyway.

That grow light packs more usable light for the algae growth compared to a warm 2300 CFL. It looks good!! I would stick with what you have.
