dandelion Posted December 30, 2016 Share Posted December 30, 2016 Can't really see... Maybe just GHA that looks dark in the shadow? Link to comment
Canadianeh Posted December 30, 2016 Author Share Posted December 30, 2016 ou can't see it? It is fuzzy dark thingy. Here I took more pics and let the natural light in. Link to comment
Newstead Posted December 30, 2016 Share Posted December 30, 2016 Some type of sponge??? Link to comment
patback Posted December 30, 2016 Share Posted December 30, 2016 All we can tell is that there is something vague on a rock. You need to get light on the actual subject and try to focus in a bit more. If you tap in the middle of your phone screen it should focus in on whatever is in the center. Link to comment
RT_BRS Posted December 31, 2016 Share Posted December 31, 2016 My bet is on sponge growth. Where did you get the rock, has it been cycled or kept in a sump? Link to comment
Canadianeh Posted December 31, 2016 Author Share Posted December 31, 2016 My bet is on sponge growth. Where did you get the rock, has it been cycled or kept in a sump? It looks a lump of hair though. I purchased brand new dry rock and it has been in tank since I day 1 Link to comment
Clown79 Posted January 1, 2017 Share Posted January 1, 2017 It may be a ball of hair algae Link to comment
Canadianeh Posted January 1, 2017 Author Share Posted January 1, 2017 It may be a ball of hair algae Emerald crab is the solution? Link to comment
Clown79 Posted January 1, 2017 Share Posted January 1, 2017 An emerald crab may eat it, it may not. Manual removal is the best method if its hair algae. Its hard to say by the pic Link to comment

ajmckay Posted January 4, 2017 Share Posted January 4, 2017 Weird... The rock looks quite new... All animals accounted for? It could just be something that got stuck in the rock before putting it in your tank and over time it's loosed itself? If it grows back quickly my guess is sponge though - looks too dark for algae but sponges do grow in those little crevices. Link to comment

patback Posted January 4, 2017 Share Posted January 4, 2017 Is it silky? Looks like hair algae to me Link to comment
Canadianeh Posted January 4, 2017 Author Share Posted January 4, 2017 Is it silky? Looks like hair algae to me kinda silky and fragile Link to comment
ReefWeeds Posted January 4, 2017 Share Posted January 4, 2017 Looks like hair algae to me as well. The tank looks new, don't get a crab or anything. Just yet. Just manually remove the stuff Link to comment
Canadianeh Posted January 4, 2017 Author Share Posted January 4, 2017 Looks like hair algae to me as well. The tank looks new, don't get a crab or anything. Just yet. Just manually remove the stuff I can only remove a tiny bit of it. I can't remove the rest in crevices. It's impossible without taking the whole rock out. That's why getting a CUC to eat it is more attractive option. Link to comment
Clown79 Posted January 4, 2017 Share Posted January 4, 2017 There is no guarantee that cuc will eat it. Many will tell you their experiences of buying cuc "known" to eat certain unwanted things but its never a guarantee Link to comment
ReefWeeds Posted January 4, 2017 Share Posted January 4, 2017 There is no guarantee that cuc will eat it. Many will tell you their experiences of buying cuc "known" to eat certain unwanted things but its never a guarantee Exactly this. If anything, get some snails that eat hair algae. It doesn't look like there's much of it so getting a crab, well, they're opportunistic and if they don't eat that or get hungry after finishing off the hair algae, they will eat other things in your tank such as corals.

Muraki Posted January 4, 2017 Share Posted January 4, 2017 Get a siphon next to it as you use a tooth brush to get it all off the rock. If it is an unwanted algae, it's worth the extra work removing it now. I pull rocks out of my tank all the time and take a brush to them and rinse the area I cleaned with fresh water all the time. Prevention and immediate action are often the best solution, don't rely on animals to do a job that you can do better. Link to comment

Prevention and immediate action are often the best solution, don't rely on animals to do a job that you can do better. I have 3" sandbed and part of the bottom rocks are burried in the sand. If I pull the rocks out that means: -I may have to break it off due to it is glued to another rock -I may have to dig all the sand out when I need to put the rock back so that I can place the rock directly on the eggcrate -the clowns, anemone, and corals may have to spend outside for a couple of hours I have chaeto in the refuge chamber and running Chemipure Blue right now. I don't understand why would I still get Algae? I feed once to twice a day a tiny small pinch of pellet food the clowns. Should I do larger water change? Link to comment

It takes a lot of macro to out compete other algae. Your Fuge space needs to be at least 20-30% of your tanks volume to really make a big difference. Your rock looks so new, I think you can just use a siphon and a tooth brush to get in there and suck it all out. You can also use a smaller vinyl tube and a stiff straw with some tooth brush bristles super glued to the end to combine the two and really get into the nook. My fuge is 90% the volume of my display, but with my stocking and bad habits, I still get unwanted algae, but it remains controllable and removable as long as I get to it early on. I had one of my fuge lights go bad, and while waiting for the new one, just that change alone started growing GHA. Got the new light, manually removed all the GHA, and it has not come back.

One thing that I found it interesting is, this dark thingy can be found only on the connection where I apply Fauna Marin glue to joint two rocks. They actually on the glue parts and not on the rock. They also happen to be kinda facing away from the MP10 and tucked in. Is it possible because of low or no flow area this thing came up? Link to comment

Very possible I would say. Along with the Marine glue leeching something it could be using to grow. Again, just use some manual removal and as the glue ages it should go away if you keep up with it. I'm still not convinced it is GHA. It's just in a space that is to dark, and all your rock is so white, you would see more evidence elsewhere. Shine a light into the area and get better pictures. Hopefully more chime in, I'm a lazy reefer and still consider myself a rookie. Link to comment
