    I have a 12 gallon nano that has two clowns a LTA and about 10 lbs of LR. I have an issue with my pencil urchin who seems to have a ton of old coraline growth on him. The urchin's spins must be filled with phosphates as the only place I have anything green is on his spines. He looks like a green...

    Just recently got a pencil urchin and he has just about whitened all of my LR which was covered in coraline algae. Will it come back or should I nix this guy. I liked my LR pink not white. thanks

    I think i starved my pencil urchin. I have had it for years in differnt tank. Put it in my 90, Thought it had enough coraline algae on rocks and glass. Spines started to fall off , one by one. Put him in my 3 year old 60. After a few days still falling off.Done a little research i know stress...

    I ordered some fish/inverts from a different vendor... nothing too unusual, but nice to get something new... and... you can use your new discount if you were lucky enough to get a UPC. I'm not positive the barcode works, so you may have to enter the code at the bottom or have them to enter it as...

    I've been plagued by the ich gods again putting my guard down for a year. I'm leaning toward taking out all my fish and put into hypo salinity, leaving the display fallow, but I'm afraid if I use the tank I have, it will be too small. This happened a year ago and put fish in a 10 gallon tank and...

    I would like to get an urchin, but am unsure of which one. I like the tuxedo urchin and there is a 'Royal Urchin' at a lfs. The royal urchin is a purple colour, about 3 inches in diameter. I would like it to eat any hair algea/bryopsis (if possible) and my coralline is growing everywhere so...

    Hi everyone!!! Remember me? hahaha okay...I've been busy for a while, but still staying on top of my tank. However, I'm very confused...as for the past 3 or 4 months, I've been battling a HUGE algae problem. But the WIERD thing is...my corals are doing better than they've EVER done. I...

    I've been reading through various threads and have gotten LOTS of great info! This is a fantastic online community, so I figured I'd post here. I'm looking to setup my first saltwater aquarium and have some ideas of what I want in it, but I've gotten so much contradictory information, I don't...

    I have a really bad hair algae problem. Looking for a way to get rid of it. I just got a new skimmer, I think that was the problem before. Should I dose sugar, if so how much for around 90g?

    My neighbor just bought 8 Berghia Nudibranches. He has aiptasias BAD, and I gave him the link from a site I found online. If anyone else has aiptasias, these guys eat them, and them alone. In 3 or 4 months hopefully, they will have eaten all of them in his 75 gallon tank. Problem remains if...

    Hey everyone, The pencil urchin that John (LedZepplin) gave me is ready to move on to the next tank. Let me know if you want to take him. NIMAS members are given first preference. If noone wants the urchin, then I will bring back to MWC. -Joe LedZepplin - Originator pre May Bklynmet - May...

    I just found out I will be leaving town, and have to sell off all my reef stuff. I have 3 aquaria. I have not had a lot of time to keep up with the cosmetic appearance of these tanks lately, with the result that there is a moderate bubble algae problem in one. Otherwise everything is healthy...

    I was moving the ph that the pencil urchin decided to redirect into my sb today and 1 of the neon gobies started to clean my hand. The rest of the fish hide when I reach in but his little guy came right up and was swimming all around. I heard the shrimp will do that also, I just never put my...

    Well, I know it is partially my fault, but green hair algae has all but ruined my love of this hobby. My tank has looked like an Irish Chubaka since late November. I had the entire tank disassembled in late January when it was moved from Woodbury to Cottage Grove and the entire tank scrubbed and...

    I went over to MWC today to figure out what to do about my hair algae problem. Jim said a lot of times nitrates do come in through the salt mix you're using, but I use Instant Ocean so I'm not sure the exact cause of my problem. He suggested no chemicals to control it, but a Pencil Urchin. So I...
