I must have missed the PM? Use 660nm deep red primarily, you can add a blue 455 and WW maybe too, but you should have roughly 6:1 red : other, or somewhere near that ratio. 1 3W per 4x4 is what I...
Don't dim, just go less hours. If you go by the minimum LED 'guideline' of one 3W LED per 16-20 sq in (4x4 to 4.5x4.5) this is especially true, IMO
Yes, if the light has to pass through the screen to get to the other side. Once algae grows thick enough, no light will be transmitted and therefore none reflected.
Also you can read through the latest iteration of the Basics here http://algaescrubber.net/forums/showthread.php?1291-Algae-Scrubber-Basics-The-Summary (written by yours truly). Go to the Feb 17th...
Um, kerry, that's this thread LOL
Minimum is 12 total watts per 12 sq in, so you could go 12w on each side of a 24 sq in screen, but 24 per side would be better. If all that light is "captured" by the screen, then you can go 1/2...
It's my preference, but I think a 2 cube/day screen is really a minimum, unless you know for sure that you're not going to feed any more than 1 cube/day. so 5x5, which is a nice fit for a 23W CFL...
In other words, use a rotifer sieve to take out all the water. I would think you could feed a cubic buttload of rotifers to equal 1 cube/day.
Also how do you propose to feed the water to the screens? With the lamp in the middle how are you going to protect it?
No, those are examples of the cube-equivalents of each of those types of food. Each of those lines equals one cube of food and a 12 sq in screen would handle 1 cube of food per day, or the...
you're over 1W / sq in so that's good. You don't care about equivalent wattage, only actual. I don't know if you could go too much larger without spending a lot.
That's been a point of contention. We always say 1 square inch referring to the dimensions, not the area. Thus a 10 x 16 screen is 160 sq in and would need 160 watts of total light. It's less...
