    How do i get rid of to much iron in my tank?

    My yellow sps collonies are starting to get a greenish tint.
    Phosphates and nitrates are very very low so its not that.

    Any ideas?
    Fewer water changes?
    At the moment only dosing fuel but i have stopped for now cause it does have iron.

    Have you tested your iron levels?

    with @459b on this one. And yes! pics.
    Bear in mind that some corals have a natural genetic dispensation to showing green flourescence, which colour were they before?
    Another possibility is the dreaded green boring algae, a definite sps killer. it does not look like an algae, i.e. you cannot really notice hairy or furry growth, just a slow green tinge which develops from the base mostly. It usually starts appearing where tissue has died due to shading by higher up branches. The culprit here is Ostreobium species. It is an indication of water quality issues mostly and unfortunately, once it gets hold of a colony, it slowly but surely attacks living tissue and its bye bye colony.
    Getting parameters back on target and stabilising often helps, but sometimes fragging healthy tissue will be the only solution. Once frags sre settled and water quality is kept on target and stabe, you should be fine.

    Lastly, it might be too much iron, which is probably caused by dosing suppliments.

    Hope I am wrong... If it is simply iron, I am not sure if GFH will remove iron, it does remove heavy metals..... Alternatively, poly filters do a damn good job of iron removal.... which reminds me..... have not seem them in SA yet.... and they have been around forever and are damn effecient.

    @ sponsors, google poly bio marine inc.

    Okey, does not sound like Ostreobium spp.
    My next suspicion would be: increased zoox density. How long have you had the colony(ies)? Remember, zooxanthellae are seen as brown...
    What sre your nutrient levels?

    I personally think your sps look great, you have a low nutrient system, and your corals have shown some growth and they are colouring up to protect themselves from the light. Iron can cause excessive algae growth, any algae? Darkening of corals, regression of soft tissues in sps.

    Very little algae growth.
    Only the yellow ones got darker as you can see from the first and second pic.
