Coraline? I hope!

[robb]

Ok it isn't the best picture but I'm hoping you can tell me what it is. I have 3 NO 40w 48" bulbs now and plan on adding 2 more soon. It is not a reef tank it is just FOWLR and a few critters. I picked up a few of the snails you see in the picture a couple of months ago and they were covered in coraline so I scraped them on a few of my rocks when I added them to my tank. It is not bright purple like I have seen in other peoples tanks but what do you guys think?
The tank was an aggressive set up with 2 40w NO's till just recently. I just added a 3rd 40w bulb. What ever it is, it was growing very slow with a 50/50 attinic and a 10K. I just added a 20K in hopes to help it if it is coraline.

are you talking about the color on the snails.. if so.. it looks like it to me the rock i cant tell..

 

[robb]

No I know the snails have it on them. It's the rock I'm talking about. I now have three rocks that this stuff is growing on. My wife said it looked like mold at first but it now has a blue or purple tint to it.

It's hard to make out but I think I can see some purple on your LR. You will notice it start to grow in circles, they will get bigger, and bigger and bigger. I scrape it off my glass in hopes to populate the rest of my tank/refugium.

Here is yet another blurry picture.
It is spreading on the rock. Not fast but it is getting to be a bigger patch. And now I have 2 other rocks that have small patches of it on them.

This was an aggressive tank until a couple of months ago so there is not a lot of LR yet.

I have 3 colors of coraline in my tank
bright pink, dark red, and bright green
the bright green seems to grow fastest, I am always trying to get it off the back glass

Robb - yes indeed - that is coraline.

 

[robb]

WhooHoo! Thanx kpogue I was hoping someone would tell me yes! Even if they didn't know for sure it helps put my mind at ease cause my wife keeps teasing me about it being mold and I am color blind.
Oh yeah chevytrks Nice looking tank!!

Just make sure that you add the appropriate amount of Ca,& Iodine and maintainn your PH and over time by the looks of your rock you should have a nice mixture of green and deep purple/blue.

Coraline comes in all colors, including various shades of purple. Looks to me like your got some growth going on in there.

 

[robb]

Wow Thanx Beth!! Comming from you I know I can bank on it!!
SWEEEEET!!
