    Po4 is high for a reef tank, i would point a powerhead at it for a week and see if it goes away, it not may be a greater problem like excess phos increase your water changed if you use RO and good salt should clear up

    how old is your system .. as new systems have "algae blooms" which clear up in time ..

    "dilution is the solution to pollution" .. in other words, like the proposed frequent water changes .. I used that salt, no problems except low KH ... are you running any phosphate media ?

    Wayne - I have not had a decent read about your issue, until now.
    You have a case of cyano-bacteria. The green variety. Yes - cyano comes in wine-red, green, sometimes blue and brown... :)

    Things you can do to resolve this:
    - water changes (this helps)
    - find the cause of your phosphates - this could be detritus in the tank, in the live rock, in the substrate, on the substrate, and remove this
    - get phosphate remover (a commercial product you buy at the LFS, or at one of our sponsors, ie. SeaChem PhosGuard, PhosBan, etc....)
    - upgrade you skimmer
    - feed less
    - increase your water flow (ie. get a power-head that delivers a WIDE ANGLE stream, instead of a concentrated jet-stream, ie. SEIO, Tunze, ReSun Waver, Boyu Wavemaker, etc).....

    You can also siphon your substrate, use a power-head to blow a stream of water on your live rock to blow out/off detritus, etc).....

    Get some macro algae (ie. chaetomorpha) and put this in your sump, with enough lighting to grow the chaetomorpha).....

    thanks jacquesb.

    well i have removed the rock where it was growing the most and flipped the crushed corel around also started with 10% water changes every second day.

    -skimmer is a am turboflotor 1000 multi sl(this skimmer was recommended to me)
    -feed small portion of food once a day.

    could the crushed coral form part of the problem?

    Wayne - the Turboflotor is a very skimmer, as far as I understand. Yes - the crushed coral can indeed be part of the problem, as can the actual life rock be (hidden detritus inside the life rock).
    What water flow do you have in your tank? Types and l/h of your in-tank pumps?

    morning jacquesb

    i thought the crushed corel could cause some problem so i have slowly started removing it from my display.
    in the display i have a minjiang 2000lph and a seio m1500 6000lph
    my return pump is a am or3500.

    Dude its the salt i can almost guarantee.
    Many reefers are having the same green cyano and the common denominater is Real Ocean salt.
    Its cheap but over time i`m finding its also nasty.
