algae

I have red algae that looks like a slime coating and also has long hairy strands. Is it beneficial, or should I get rid of it. If so, how? I attached a few photos. Thanks!

I have this in my tank... has bloomed over the course of 2 days. I did have diatoms but my lawnmower blenny solved that along with more frequent water changes etc Does anyone know what it is and how to treat it?

Pretty new to this hobby and I have some algae growing in my QT. Hoping I could get an ID on it and how to fix. Ammonia is 0, Nitrite is 0, Nitrate is 10. Tank is a 30g bio cube.

Hiya guys, I’ve been having a bit of an algae issue in my 15 gallon tank that’s been up and running for 3 months now. Is this just the ‘ugly’ stage? Which snails would be best to get rid of the algae? It’s primarily on the rock and some on the sand. I already have 1 trochus snail and 1 nassarius...

What am I dealing with here guys? It’s starting to take over the tank. Appreciate any help

Happy Saturday (to most). I purchased 20lbs of deco live rock from gulfliverock.com which arrived on Thursday, thanks Dan! I'm loving it so far and I am excited by every new thing I see. If you have seen my other posts you'll notice I'm kind of a name junkie, so as you can imagine getting rock...

So this is my first salwater tank, its a waterbox cube 20, im primarily a freshwater guy but decided to give saltwater a try, now this tank has been cycled and been running for about 3-4 months now, i have this algae build up or whatever it is, its kind of like a carpet if that makes sense. im...

Need help with the identification of this algae both the green one and the purple. Was using tap water but switched to RODI a week ago. Already had brown diatoms tank is two and a half months olds. Ignore the photo bombing cardinal

Hey guys but can someone help me identify this type of 'algae' ? It seems to be on some of my plugs as well as in my zoas.

Hi! I have an IM lagoon 25 that has been running for about 2 years now. I have this weird fuzzy growth on the rock (for about 6 months, doesn't go away on its own). It only grows in the light so its photosynthetic. It has a brownish tinge to it but also can be closer to white. It doesn't grow...

Hey guys I need some help identifying 2 different kinds of algae in my tank. Here is some quick facts on my tank. Its a 75 gallon mixed reef only 4 months old but all of my corals are doing well. 2 months in I noticed what I thought was hair algae but now I'm not so sure. Its rapidly been taking...

About a month ago I determined I had a Dino outbreak. Started using Dino X and now after 6 doses my Dino is fading, but now there’s a thick maroon algae building up. I believe it’s cyano. Has anyone had this experience?

I’ve noticed this type of algae that has rapidly starting to grow on the top of my rocks. Tank is almost 6 months old. Phosphates: 0.05 Nitrates: 5 Could I get an ID? And possibly a cause and a way to get rid. I’m also adding a new lawnmower blenny this weekend after being quarantined for 6...

Hi everyone, this is just an update on my tank 4 weeks in. I still have nasty diatoms, started getting alot of green algae. And it doesn’t look like it’s going anywhere anytime soon lol. My nitrates and nitrates are 0, and i use rodi water so i’m a little confused as to why they’re still here. I...

I have a 50 gallon cube, sump, sand, ATS, radion LED, Protein skimmer, my aquascape is fairly easy to remove in sections. My troubles with Dinos coincided with overzealous Iron supplementation and low nutrients. I lost many corals and anemones to the infestation. I am not sure if my approach...
