corraline algae

I've got bright green algae of some fashion showing up on some rock and my sand bed. I heard if you can't scrape it off its coralline. Is that true...I presume that's good? I run my day lights from 8am to 8pm and wondered if I should reduce that or not after seeing this appear? This is LIME...

Hi guys, I'm sure you get this question all the time, but I was curious if anyone could give me their opinion on if what i have forming on one of my rocks is cyno or Coraline. It doesn't seem to come off very easy when i rub it with my finger and it is in direct flow of my powerhead. I attached...

For the barebottom tank reefers, I wonder How many of you guys allows Coralline algae to grows on the bottom or the back of your tanks?

I have a fairly large sea urchin, it is a dull orange in color, I was told by my LFS to get rid of him, that he will eat all of my corraline algae, ( almost all gone ) and poops a lot. If I didn't get rid of him could I put him in my overflow box? He is so large there is no way he clogs it.

Hey, I have a bucket of a few pieces of live rock from the previous owner of my tank. Since i had no were else to put the live rock in order to keep it "live". Unfortunatly for the life on it, I had nowhere else to put in but a bucket of tap water. I've spent quite a while rebuilding the tank...

I am upgrading to a 75 gal. I want to put a sand base in the bottom of the tank. Any certain product I should use? Will sand from the beach work? Also trying to design my sump. I have a wet/dry sump that was on an old 120 gal and a 10 gal tank. I was thinking I could tie the two...

Hi all. I recently changed how my return flow comes into my tank, so now I have eliminated alot of excess 1/2" loc-line. I didn't take pics, but links are posted below. I had it connected to my 3/4" Loc-line with a 3/4" to 1/2" Y adapter and ran the circle flow assy behind my rockwork on one...

Where is best place to buy liverock online? Those ebay ads any good?

Would my livestock survive if I completely changed my sandbed and changed out all of my liverock? I'm thinking of maybe getting fully cured liverock. Even though I think my liverock is very slowly coming around it appears to have some small purple spots coming back in. I seriously me very slowly...

does this look like red slime to you????

I get this brown haze of algae growing on the acrylic. It's pretty hard to scrub off, not your typical film that comes off easily. I have to scrub it pretty hard with an acylic pad to get it off, almost like coralline. It also will grow really long hairs out of the center of the spots that...

I have a nice 54 gallon live rock, live sand, soft corals and fish tank that's done well for about 4 years. I use the two-part ESV B-ionic calcium/alkalinity buffer once a week. Very recently, there's been a seeming growth spurt in pink and purplish corraline algae, especially on the glass...

I have had my tank for about 3 years and I have about 50lbs of live rock that at one point in time had very much corraline algae on it. However, due to neglect on my part, the once purple rocks have either turned bright white, or purplish white. It seems to have lots of "debris" on it. But...

Hello. A couple months back, I bought some fragging liverock from Premium Aquatics. Acutallly, I bought waaay to much for my little 65 gallon tank. I just pulled it out and it's sitting in a bucket with water. I'd say I might have 30 lbs (to say on the safe side). I'd let it go for $45...

Hi! We have finally decided that we will be starting a brand new reef tank. We've never done this before so it is totally new. We purchased a Top Fin Aquarium Starter Kit 20 gallons from Petsmart. It's still in the box. We are going to go with just a 20 gal. to add some beauty to our home...

Just looking for suggestions on urchins that won't leave traction marks in the acrylic. Do they all eat corraline algae? I may be wanting something to control my pink corraline soon.
