You can see at the bottom where its actually green. That looks to be the part that is submerged in your sump. Maybe you need higher flow since it appears the part thats fully wet is actually green....

Did you replace the 1w with 3w? Looks like you are still using the expressions LED strips.
The sizing guidelines say for LED, use half the wattage. If he was at 46w per side before, half would be 23. He is at 18. Would a 5w shortage be that much a difference?
Does it matter if you reduce the width rather than the height? I was under the impression that 50sq inches is 50 square inches. Sealing half the slot isnt as easy as cutting the screen in half...

How long did it take before they shorted out? Where I have them they have the slightest amount of salt creep where the wire goes in. Its barely enough to rub off so I...
I'm pretty sure that these cant be beat http://www.expressions-ltd.com/Algae_Scrubber_LED_Light_p/led-grow-light.htm
If you are feeding 3 cubes then you should be fine as long as 36 sq inches of screen are getting adequate light. I was told at one point its ok if your screen is too big (like making it long enough...
Santamonica can you explain your FW comments? You said on the previous page to not use FW in the scrubber, but then just said to soak in FW. Are those not contradictory?
Are you using the spiral CFLs? Or are you using the CFL floodlight? You want CFL floodlight.
Hes running one CFL per side while I'm running two per side. 90sq inches of screen means I need at least 90 watts. I'm at 46w per side for a total of 92 watts.
If its a dark brown I think you want to run lights longer. Maybe 20-21 hrs until you get greener. If light brown then yeah move light back or reduce light.
Are you using a reflector of any sort?...
Wonder how much shipping to MN would be?? I keep missing the pod sales on Reefs 2 Go :(
That LED bulb in that link is crap for ATS purposes. I tried it for a month and the CFL floodlight it replaced did a much better job. Since then I have found an 18x3w bulb on amazon and am still...
Clear/white or no growth means too much light. Dial it back a couple/few hours or move the LEDs further from the screen. If growth starts to get really dark/black, then you have gone too far and...
I was under the impresssion that jet black meant more hours of light and/or more flow. Very light green/yellow growth would indicate dialing back the hours.
I would ramp them up from half power,...
This one is 9*3w. Could you compensate for the reflector by getting the 12*3w or 18*3? Seems like you'd have to have the bulb somewhat far away from the screen with 18*3w to keep from burning so...

I'm surprised more people arent agreeing with Santamonica. Think your live rock as a P sponge. Once it cant absorb anymore, you get algae in the DT. Your readings are always low because the algae...
For simplicity sake, I'd like to oversize my screens...if at least a portion of the screen is lit correctly, does it matter that the rest of the screen is under lit/not lit?
I have dual overflows...
Right after the screens are cleaned, there is an uptick in N & P until algae regrows on the screen to consume it. It has been suggested that if you have two ATS's running and alternate your...
