    i thought i was getting a cyno problem but after a three day black out it seems to be getting worse also it looks like some form of brown/green algae growing on the sand and is seems hairy not slimy
    it mainly grows on the new sand i have topped up in the center of the tank and this kiln dried sand is from a different supplier anyone any ideas
    thanks

    Hi Stuart, are you high or low tech? Are you dosing Co2? I had an issue on a high tech planted that was 2ft deep. Flow wasn't high enough to get Co2 down to the bottom of the tank, the sand would get covered in algae in about 24 hours. I increased the flow and it cleared quickly, I even found I had to reduce the amount of Co2 I was dosing. Shortly after that I gave up with high tech planted, I never felt happy with the balance between fish health and vigorous algae free plant growth. That is just my ineptitude!
