    I noticed this red algae looking stuff growing on my plants in my refuge. It's not stringy or at least what I thought to be cyano. here's some pix of the stuff. hopefully someone has an answer to this for me please. not sure to leave it until it withers away or remove it.
    Thanks. Dave

    Gfo contains iron and can actually fuel cyano.

    o damn. I thought the GFO removes the phosphates that fuel it. I didn't know that iron also fuels it. damn :-( you can't win lol

    When I had cyano on my chaeto, I switched to feeding the fuge with filtered water. Greatly improved the cleanliness and growth rate on my chaeto.

    Do you filter your display water through a sock before it goes to your fuge or feed it directly to the fuge from the overflow?

    I found that my chaeto was acting like a big detritus filter and I was gettting some cyano growth on it. That stopped when I rerouted my overflow to filter socks and feed the fuge filtered water.

    I use felt filter socks before the fuge. I have one of those aqueon proflex sumps with the filter socks.
