Greetings all! Hopefully you can help with a project we have ongoing since we really need adult supervision!
We are culturing both Azola and Salvinia for use in a wastewater project. Some details:
The tanks are 36" long by 18" wide by 6" deep.
There are glass lids on the tanks.
Lights can be as close as 4" to the surface of the water.
I'm only interested in lighting that will make the plants happy!
Since we have dozens of these tanks, it seems prudent to build light strips that cover multiple tanks. I've plowed through many vendor sites and get more lost as I go! Much of the information I'm finding for planted tanks involves light penetrating to the bottom of the water column. Since I'm working with floating plants on the surface, I'm guessing I can go with lower power LEDs (or dim them?). Having too much power, in this case, is a negative since it will add to the heat load of the room.
I currently have a Beamsworks 36" unit (6500K) on another tank that seems to work great with the Salvinia. It's 6" above the water and gives me a PAR reading of 33. If I could get something similar in a coil so we could build our own strips, that would be great. To me, this is very similar to an algal turf scrubber in principle.
Any advice would be wonderful!
