What types of Macroalgae do you have in your Reef System? Are they beneficial so far?

[dstockwell]

I have Halimeda and came on live rock, chaeto in sump, and whatever this is.

What is this?

 

[JoJosReef]

I’ve got some acid rain and Pom pom Gracilaria

Where did you get that?

 

[i cant think]

I used to keep macroalgaes of all types and the reason why is due to the natural looks and easy of care they hold. Unfortunately this ended up stopping and I now work with SPS coral (And a mixed LPS/Softie reef).
Though I will take any macros I get as hitchhikers!

 

[atoll]

Ulva intestinalis which I grow in my Turbo Aquatics ATS.

I've got a RS 425 moderatly stocked, and I run chaeto in an Aquamaxx media reactor that I DIY'd in to an algae reactor. I only need to run it 5 hours at night and it keeps my nitrates in check.

So what is this?

Current macroalgae/plant list in my planted marine tank:

Brown:
N/A

Green:
Caulerpa brachypus
Caulerpa lentillifera
Caulerpa paspaloides
Caulerpa prolifera
Chaetomorpha linum
Chaetomorpha spiralis
Cladophora sp.
Halimeda opuntia
Udotea flabellum

Red:
Corallinales sp.
Cryptonemia crenulata
Gelidium robustum
Gloiocladia sp.
Gracilaria curtissiae
Gracilaria hayi

Seagrass:
Syringodium filiforme

 

[WheatToast]

Clasic chaeto for nutrient export, and another one, not sure what species, i got it as a hitchhiker on some rock, feel sorry for her, so.....

Halimeda opuntia. Requires calcium.

 

[WheatToast]

So what is this?

Some species of bladder-lacking Sargassum. Brown macroalgae in this genus tend to be difficult to care for, requiring high light and flow.

Alongside Neomeris annulata:

I just removed a literal pound of chaeto from my 15 gallon sump.

How do I know it was a pound?
I weighed it.

The entire refugium space was completely PACKED with chaeto. I have a feeling this might be why my tank has been suffering really bad lately. The refugium was literally stripping everything out of the water column.

I used Caulerpa for over 10 years, I specifically like that it attaches to rocks and substrates and stays where you leave it. It was brachypus (sp?) and not taxfolia which is illegal in NSW. Never went sexual, never got out of control in the display.

I'm using Chaeto these days and it's working a charm. No gfo, no nopox/carbon, no lanthanum. Phosphates always under 0.1 and nitrates never over 6.

I have it under a prime fuge which makes it grow at almost unbelievable rates. The algae is only as good as the light.

 

[ReeferHD]

I have chaeto and gracilaria growing wild in my fuge, thinking about adding some gracilaria to the DT

 

[educatedreefer]

Used to have chaeto, but found their rapid growth, and thus rapid absorption of nutrients, AND funny-looking shape to be weird in my sump so I changed to green/red algae such as Ulva, grape algae, Dragon’s breath, and mermaids tail to give the refugium a bit of variety and pizaaz!

 

[Hermie]

beneficial is the hilarious keyword here

I'm pretty sure my over abundant chaeto has been slowly destroying my tank.

 

[sixty_reefer]

I’ve got some acid rain and Pom pom Gracilaria

Acid rain has to be the most crazy algae in the hobby

this were my frags

and my favourite to date, almost mushrooms look alike.

I love both of those! How/where to get them? Under what water conditions/lighting can they grow?

I believe the best place to start from is with killerkosar they fairly hard do come by. They do well under the same parameters as you would for sps. Unfortunately I don’t have mines anymore.

 

[RichReef]

I'm not sure if an ATS counts but you can find 99 percent of my algae there in the form of GHA. Nothing in the display or refugium except film algae.

 

[marcus aurelius]

I keep some beneficial macroalgae in my reef system from time to time.

Love your IG..

I'm about to upgrade from my 125 to a 180. I was wanting to plum in a 40 breeder for a external refugium.
Thoughts?
