    Hi All - I am battling with a nitrate spike that just won't quit - I've been doing +-40% water changes weekly the last 3 weeks or so and no change. So ... I want to try the chaeto in the sump experiment and see if it works. Does anyone know where in Gauteng where I can get hold of some please? Have tried several LFS with no luck.

    Is high nitrate also harmful to corals ? ( or just fish ? ).

    My other parameters are :

    PH 8.4
    Ammonia : 0.25
    NO2 : 0
    N03 : 60 + ( tested directly after water change, with 2 test kits )
    SG : 1.025
    Ca : 400
    KH : 10
    Temp : 24

    Any other suggestions on how to reduce it rapidly - or whats causing it?

    Tank specs : Display 270l
    Sump : 120 lt / DSB
    Skimmer : Small Boyu

    But any info on where this elusive chaeto might be hiding would be great thanks !

    What test are you using? You could try Prodibio, Seachem Stability or Brightwell's Microbacter to reduce your nitrates.

    Purigen is also a good option to reduce Nitrates!

    How old it the tank?
    I'll let the guru's advise but would you not force your tank into a mini cycle if you're changing 100l per week. I would guess that you may be removing a fair amount of good bacteria that with time will help reduce your nitrates. My logic anyways...
    If its cycled already then I have no answers apart from the usual, reduce feeding, skim wet etc.
