How to get rid of black algea?

  • We are currently upgrading MFK. thanks! -neo
I've had a prob with it for ages can't get rid so any info will help me also , I've found only way is to scrub it off I've gad to throw loads if plastic plants ways even boiling water won't shift it
 
You have to find the right combo of lights/nitrate load. I had it for 2 years! Scrubbed, tore down tanks, finally after a very long time and a lot of trial and error, and a change over to mostly LEDs on my non-planted tanks....it's gone!!!
 
I had a problem with that stuff a while ago. It was even messing up my sealant at one point. I got a dimmer light, left it on less, removed what I could, started doing extra water changes and it never came back.
