Algae turf scrubber

leepink23 · Mar 4, 2017

Wondering if anyone would know why algae doesn't grow in the center of the light? I have cleaned it twice, has been running for 4 weeks and every time it still doesn't grow in the middle. 2 32 watt led lights running 12 hours each night

The light in the center is too strong. I'd move the lights back some.

Or put some kind of diffuser like a pink or white frosted.

I rechecked and they are 24 watt each, since I can't move them back I will look for a diffuser. Thanks!

I was able to adjust the center lights back by about 2-3 inches. If that doesn't work should I buy a lower watt led versus trying to find a diffuser?

+1 on the diffuser

rough up the screen where theres no growth, with a hole saw, or even carefully with a razorblade, really rough.

The screen is new, give it a bit longer, it will grow over.

Hey The rest of the screen is growing well. Consider not worrying about it ? Also where did Ya get the lights?

I moved the lights back and just going to watch for now, where would I find a diffuser? I have roughed up the area its not growing several times with a hole saw but will rough it up again. I got the lights on amazon, marshydro 24 watt.

Don't stress at all. The growth is fantastic for only four weeks.
The hole will be gone soon enough.
