    Had my tank running since beginning of October. Refugium going well. Display tank coming along nicely with no worries However, in the sump, mainly the first chamber where the sock and skimmer are I'm getting long string dark green algae strands coming off the sock, and clumps of bubbles in a clear mucus around the chamber.....put simply snot with bubbles in. Now, I don't know whether this is simply one stage of the maturing process or a problem. I'm kinda pleased that I'm getting very low nitrate and phosphate readings, but a little concerned about this sump algae. I'm known for being fussy and liking things clean. Not had a refugium before so no experience of them......I can understand that the light being on for 12hrs will cause algal growth, just don't like the look of the darker stuff coming off the sock and the clear gunk with bubbles in it. Thanks for any advice you can give me

    Yes Darren, I have a 6500k halogen mini floodlight (20w) on a reverse cycle. Comes in at 11pm, off at 11.00am

    if the algae is growing well it will be reducing your nitrates and phosphates for you
    i would think its just part of the cycle

    Thanks Jim. I was thinking along those lines myself. But as I mentioned I've not had a refugium before. In hindsight my last sump must have been a nitrate factory every chamber full of either sponges, alfagrog, rock or Denitrate. Good lessons learnt keep it simple.

    Hmmm, fish food, never thought of that. Great idea! Especially since I added a gold rush tang at the weekend and reading guidance on their care they like a lot of greens in their diet. Nice one Jim

    Maybe. .. Only thing is I'm going to hate actually ADDING grungy green crap to my lovely clean display tank when most of the past times all I've done is try to get rid of it lol.

    Nice one shazants. Yeah, gave it some thought and decided to leave it just where it is now. Although the chaeto is growing well, so is the algae so in the new year I'll try a different light ..... Although the floodlight is rated at 6500k which from what I've read is the correct spectrum, it does appear very bright white, so may be contributing to the good algal growth as well. Don't laugh, I know chaeto is an algae lol......
