Hi, got this macro from a friend, but not sure what it is. Can anyone help ID this?

Does anyone have any theories as to what causes the proliferation of "red coralline"? I believe the species isn't actually a part of the coralline family but rather a red thalloid algae from the genus Peyssonnelia sp. or maybe Hildenbrandia rubra. Some systems appear to have none, whilst others...

When I first put all the macros in this tank, a dino bloom quickly came about, and it was a mess. A LFS that I frequent told me to do a 48 hour total blackout, followed by 2 weeks of daily dosing of these three products: And it very much worked, the progress a few weeks later can be seen in...

I Have this 15g macro algae tank, and it’s been up for about 6-7 months, what could this be? What would I do, I make 20% water change every week.

Good morning everyone! I am having trouble with a caulerpa infestation for a long time now, i tried manual removal every week, out competing the caulerpa with chaeto in the refugium and with more corals. Also 2 years ago i took out all of the rocks and scrubbed them down, took my friend and me...

What’s wrong with my caulerpa? It’s been like this for a month. Is it going sexual? It’s been like this for a while? What could it be? Should I take it out from the tank?

I’m planning to purchase some more macroalgae for my tank, and after dealing with ich recently, I really want to quarantine them this time. Going through a 15-week fallow period was rough, and I don’t want to take any chances again. I have a smaller 2-gallon tank that I think could work as a...

So I recently moved all my corals into my larger system finally, and turned my nano reef into a macroalgae tank that I’ll be putting dwarf seahorses in. I finished all the macro scaping last week and this was the final product which I’m really satisfied with Pretty quickly the macros began...

I ordered some blue hypnea online for my dwarf seahorse tank, they sent two VERY large portions of it. The first bag that I already put in the tank seemed to be clean, but I still rinsed it in fresh saltwater and hopefully there isn’t anything on it. This second bag has hydroids attached to the...

Hey guys, I have a 32 gallon biocube FOWLR setup and a plant has randomly sprouted. This tank has been established for almost two years now and has never had any sort of corals or macro-algae introduced to it. The plant seems to wilt and die and then spring back up randomly. It has brown little...

So I have a display refugium I’ve made a few posts about and I’m battling some cyano in it. I’m thinking about doing a blackout for 72hrs to try to kill the cyano. Will my macro survive that? Or will I just kill it all?

Hello ! As the title says my question for you lovely people is do you have a Dream Pet or maybe algea that you wish to get but is pretty hard to get ? For me its by far Hypnea pannosa or blue hypnea macro algea which is here in Germany apparently extremly uncommon. Maybe you guys can share...

So I have a display refugium plumbed into my main display. In the refugium I have some what I believe is cyano starting to grow. How can I combat this in a refugium without damaging the ornamental macro algae? Nitrate is 8-10ppm Phosphate is 0 - 0.03ppm I’ll attach some photos of the what I...

Hey everyone! I wanted to start a thread mainly so that I could document this tanks big move and ongoing build for myself, and anyone who wants to follow along with this adventure. I've wanted to run a macro algae/mixed reef tank for a long time. I personally feel this mix tends to capture...

Hope everyone is well. I’ve had this macro algae growing in my overflow box for a long time. My buddy who’s been in the hobby since the 80’s tells me it’s some kind of macro algae and I’m just curious as to what kind it is since I’ve never seen it in other reefs, and I service a lot of...

As the title says, I’m looking for a AI light that will sufficiently grow macro algae but I don’t want just the refugium ones since it is a display tank. My current light is a freshwater planted tank light that seems to work pretty well. However I would like to switch to as much AI equipment as...
