I have a reasonably new 10 gallons low flow tank, just a return pump no wavemaker This project was intended to be a low maintenance tank, so I haven't been doing regular water changes -- I understand this may be a mistake with the amount of corals/livestock I have in there, but it's hard to...

I’ve had a 29 gallon Biocube for over 14 years. It’s been a reef tank the whole time and I used to put clowns and anemones along with a LOT of live rock in it but the anemones never lasted very long so I switched over to soft corals with just one small percula clown and a watchman goby. They’ve...

Hello folks, Can anyone ID this red macro algae? And hopefully get some info how to best care either in 55 gallon tank with Fluval marine light or 10 gallon with Aquamedic light.

Thank you everyone for your interest! We have enough takers for this batch and the next. Please message me if you would like to be added to a wait list since we need to harvest this macro every 3-4 weeks. Thank you! Gracilaria curtissae I’ve had this macro in my tank for a year and it readily...

Is this Gracilaria Curtissiae ? need accurate Id but I’ve been calling it Gracilaria. LFS calls it dragons tongue. And is anyone interested in taking some off my hands? We’ve already fully stocked our LFS and it just keeps growing! :) Side note: we keep a natural tank with pests such as...

Hello guys, I’m need some help to ID this Algea bloom in my tank. I had a lot of hair algea in my tank, so I did a fluconazole treatment, and it worked really well. Then I did a large water change, and after that I got this green algea all over the sand. I know my nitrates might be high, but...

I have this red growing On a good bit of rock is this normal? what is it?

Had some red algae pop up maybe a year after I bought a small piece of live rock. Have seen similar different species in ID threads but unsure. I think it's attractive and would like to keep it, just want to make sure it's not invasive or problematic in any other way. So far so good hasn't...

Hi guys Got some algae issues. But before I go ahead and do something about it I wanted to ask your help to identify the algae, so I am 100% sure. I think it’s green and red Cyano bacteria. But will be great if you can please help. Tank is about 3 months old. Cheers, Shiv

The seller thought it might be Dragon's Breath but it doesn't really look like it to me.

Can someone please help me identify this red algae? How do I get rid of it? It seems to be spreading fairly fast and starts out as a mossy looking growth with air bubbles coming out of it, I thought it was healthy at first... there are also tiny little white, or clear/transparent ant looking...
