    What does it feel like? You get all funky colours of coraline but they generally dont last long

    The green coralline alga are becoming more and more common, especially with LED lighting. It is just as welcome as any coralline algae, so not to worry. I find it grows mostly in the deeper parts of the tank, which I wouldn't have expected, seeing that it is green. I've never experienced an explosion of it, just discrete spots, which looks really nice against the violet, purple and red corallines.

    If its not fuzzy dont worry, all my rocks I have ever placed in my tank have gone that greenish colour where they are not covered with corraline...it could very well be coralline growth it comes in pinks, purples, reds, whites and greens commonly...lighting etc can play a factor in these.

    Is the tank exposed to direct sun light?

    @sergio I do have a skylight behind the tank, tho it does give light to the room but I don't think direct rays actually reach the tank as the skylight is on top of the roof and the is quite high. At the same time the back of the tank has a lot more green then the front.

    I wouldn't worry about it getting out of hand. Your tank is still new and as Kunhardt mentioned, if it's not fuzzy, it won't be a nuisance. With time, the red-purple forms will dominate.

    Also, any natural sunlight, even indirect, can increase algae growth. As your sunlight is coming from a skylight, it will be pretty well distributed and the effect will be less obvious, but still there. That said, if you can keep nutrients low, it shouldn't become a problem, but you should know it can be a factor.

    You know, I've heard that, when you have green coralline algae, and if you listen really carefully, you might hear your rocks singing... "It's not easy being green..." ;)

    I agree, anything green outside of the scrubber area makes me so nervous. And I have a reason to be nervous, I have had my share of the green stuff and some of them even had one or two bubbles in it.

    I still think from the looks of the rocks in most of those pics that its just green coraline and micro algae...its hard to tell though with some of it from the pics if its fuzzy or not, as I said before if its fuzzy then you going to have problems...if its smooth and hard dont worry about it.

    That purple...hmmm... from the pic it could be cyano thats gone stringy...if that makes sense...doesnt look like red hair algae though. Never heard of a purple hair algae to be honest.

    Thats some cyano,also looks like some purple hair algae. What your water parameters like? po4,no3 ? your tank is still new so its normal to get some algae blooms. How much and how often you feeding?
