algea scrubber

i have a question for all of u algea scrubber people out there. i set my scrubber 3 weeks ago and the only growth i got was a slimmy looking brown algea so it took it out and scrached it up alot more and then i put the light closer to it will this help

 

How many hours a day are your lights on?
Week one you should completely clean off all algae.
With a new scrubber when you get black / brown "oil slick" growing clean it off.
It's good you scratched it up well.
There are many things that need to be just right.. Like flow for instance.
How much flow do you have over the screen and what lights are you using?
Also really high nutrient tanks will have the oil slick longer.
A picture would really help.

 

I will post a pic tomorow after school it about 150 gph and the lights are 50 w . I used sand papper and a knife to scrach it up it was 50 g sand paper I got this idea from saint he told me to do it to get rid of my dino. I almost read the entire post the u always tell people to go on for info

 

O and the lights I only had them on for 8 hours but now I was told to change to 18 hours

 

Yeah.. just checkin some people run them 24/7 for a new scrubber and you can't do that. I run mine 12 on 12 off but 18/6 is good.
You should have enough flow for it to fall off in a solid wall of water.

Here's a guide for flow depending on how long the screen is:
Screen Width-----Gallons Per Hour (GPH)

2" 70
3" 105
4" 140
5" 175
6" 210
7" 245
8" 280
9" 315
10" 350
11" 385
12" 420
13" 455
14" 490
15" 525
16" 560
17" 595
18" 630
19" 665
20" 700

 

I run two 23watt 5000k lights on mine.works well
