    looks more like some kind of macro algae.

    Another picture from the side can help.

    It is a macro algae called a lobophora.
    Considered a nuisance algae as it covers the rock and can spread (albeit slowly).

    perhaps a Sargassum species of Macro Algae.. is the rock new? If so it could be what was on the rock when you purchased it, and will die off without the proper light ect. My suggestion is to get a fish that will eat the macro algae...a herbivore like a blenny or a tang.Even an urchin will work

    I also see some red slyme algae starting. This would suggest to me that you don't have enough flow in that part of the tank. Adding another powerhead or increasing the flow might help with the algae

    Thanks guys. Its in my preds tank so don't want to add any more fish. will monitor it as it grows. Hopefully it doesn't get too big.

    Yip not a lot of flow in that part of the tank. actually not much flow at all in the tank. Will add another power head. I know my lion fish are not big fans of too much flow though.

    I would suggest to then move that rock to a area that is closer to the powerheads perhaps and leave that part for the lionfish to swim in seeing that it does not have alot of flow.:m106:

    Agree with Tekkengal. I had some in one of my old tanks and thought the shapes it grew into was quite nice, never had any trouble with it.

    I agree with Lobophora.
    Not really a major problem as it does not grow exceptionally fast, more of a problem in the sense that if it is growing it means your nutrients are high as they like high nutrients and judging by the other algae from the pic it does look like your nutrients might be a bit high.
    If you lower your nutrients it probably wont survive

    Another option is Padina Sanctae Crucis but more likely Lobophora as the Padina species is a bit more finicky and also reliant on high calcium levels

    Actually you can check by touching, I just remembered.
    Lobophora will be slimly
    Padina will be hard (due to the fact that is a calcium user)

    It is soft and slimy :) I don't dose my tank at all so cant imagine why the nutrients will be high. My nitrates are very high though, but being a predator tank that is expected.

    The formation that it is growing in is great though. So if it isn't a problem I will just monitor it and see how it goes. That area of the tank does need a little more flow so I will be getting a small wave maker today and pointing it over that area.

    Thanks for all the help.

    Answer in red.
    Nutrients in a predator tank is common but not really a good thing, if fish are exposed to high nutrients for long periods of time it is not very good for them.
    Also some predators (sharks, rays, etc) are not fond of high nutrients from the get go.
    What is your stock list for this tank?

    I have three lion fish small ones a maroon clown and a blue ribbon eel and a smallish grouper. Also three large hermit crabs. The tanks is 1200x500x550. I am pretty sure its at its maximum capacity and I have no intension of adding any more fish.

    He is very cool, can give him a scratch at feeding time. :)

    I have about 50kgs live rock in the sump and a bubble magus Mac 3 skimmer with some ceramic cubes. I am limited with space in my sump.

    Honestly I can see your ceramic rings being the problem.
    IMO they do more harm then good.
    Why not consider running something like Bio Cubes or NP Pellets (don't know how familiar you are with pellets though)
    They are both great filtration methods and especially if you are limited for space.
    IMO I would consider changing filtration and slowly getting rid of the ceramic rings and even the Live Rock in the sump both of those in a predator tank are just places where waste gets trapped in
