    Keyaam, if they appear as blotches like how our normal (pink) coralline algae is, then it is coralline all right. Otherwise I would think it is just that annoying green algae caused by nutrients.

    It has the same characteristics as corraline in appearence. If you look closely at the back glass you'll see the blotches

    Keyaam, what you are experiencing, I highly doubt it is a calcium based algae. I've also got some of that green stubborn algae, aswell as the green coralline.

    I just need a definite ID on the algae and what could be encouraging its growth.

    Hello Mekaeel,is the stubborn green algae caused through elevated nutrients.It is very similar to corraline and can only be removed with a blade or credit card.

    can you see it growing with concentric rings, normally white or slightly transparent on the outside and then coloured to its centre?

    Keyaam - I have found the following:
    - you do indeed get a form of green corralline algae - but this is a precursor to the pink/white/purple/dark wine red corralline algae that normally grows in our tanks. The green coralline algae does not live as long as the other forms.
    - you also get a green stubborn micro algae, that quite often starts to grow on the glass of our tanks.

    Both of these, can most likely ONLY be removed using a glass-blade (scraper - like Frans suggested). The first form, you will only ever see in the 1st 6 to 8 months of a tank's existance. The latter, you will most likely encounter for the REST OF THE TANK'S LIFE.

    Unfortunately, have I not found anything that eats this stubborn micro algae (yet), neither anything that totally removes it from my tank.

    As you know - I have a huge skimmer, some decent lighting, but this algae still keeps on growing. My SPS corals is growing relatively fast nowadays - so my phosphate levels cannot be TOO delibitating.

    I also run chaetomorpha in my tank's sump - and it grows like crazy.... so - why this algae would still grow - I dunno - there must STILL be something feeding it.
    Or, it might feed on some chemical compound that I don't remove from the water.
    Or, also - it might need to little phosphates/nitrates to grow, that the little there is present in the water, is enough to feed it to grow.

    Good luck! Enjoy cleaning! ;)
