    I have this red algae that has popped in my tank about three weeks ago. I do 15 g water changes every week w/R.O. and all of my levels are in spec
    Amm 0
    nitrite 0
    nitrate 10
    phosphate 0.05
    pH 8.4
    alk 3.5 meg/L
    Temp 78 F
    Water turn over 12x p/h

    All was going well until this red algae? showed up, any ideas of what it is.  And would it cause my feather caulerpa to melt into a pile of green slime, because that is what happened yesterday. Any ideas of what the red stuff is or why my caulerpa died. pictures are in my photo album
    thanks for your advice in advance

    I feed every other day, learned the hard way by feed to much ,had hair algae everywhere from excessive phosphates. I have been using phospoban for the last two months along with reduced feeding to keep my phospates in check. I started the tank in July. The lights are on a timer and run 9 and a half hours a day.

    I do use RO Water as top off or in a pinch I use DI water. All fish, shrimp, and snails are accounted for no deaths in this tank since start up(quarentine tank has seen some fatalities though). As for additives I add the recommened amounts of Iron(for the caulerpa), iodine, calcium, superbuffer and essential elements every week after my water change. All products come for Kent. Do you think that is to often? Coraline algae has been growing well as well as my caulerpa(up until a few days ago when it all melted)

    I use Instant ocean, and I use superbuffer because the book I read by Fenner said to add weekly because the buffering capacity in saltwater aquariums.

    [b}I'm assumingthat you are referring to cyanobacteria. It may be the case that the cyano is out competing the feather caulerpa.

    Another possibility is that the caulerpa went sexual. When caulerpa goes sexual, it generally turns white and disintigrates releasing all of it's store phosphates and nitrates back into your sytem. Going sexual is caused by respiration and a 24/7 light cycle, good in a refugium, will avoid the respiration.[/b]

    My refugium does have 24/7 light but I don't know what respiration is. Please explain. I though I had to run the lights 24/7 do I?

    Thanks
