EDIT TO VIDEO: Please note only Caulerpa macroalgae are a single cell with many nuclei. All other macroalgae is multicellular AFAIK, however if i'm wrong about this no doubt somebody will correct me. en.wikipedia.org/wiki/Caulerpa

You fill Sir David's shoes extremely well mate! Thank you for sharing your excellent knowledge

My Macro Algae reef tank was by far the most beautiful Marine setup I've done!

This is the second time around I've watched this. Il admit the first time around it didn't really grab me. This time round though I truly appreciate how unique this video is. Your tank is stunning! It's really difficult to find display tanks that are far more natural with the use of macros. Spot on with the information as well.

Cardinals remind me of rams, I am thinking of doing tanks side by side one reef and one planted. But now I'm considering macro algae instead.

Very cool and informative video!!!

Great video and thank for the links also

Any macro talk, is good talk :)

that's an awesome tank!

Caulerpa ability for rooting in rocks its crazy! Nice video!

Great video! 😀

Nice video :)

i have heard that you can keep macroalgae in brackish aquariums too. is this true? if so, do you know how the maintenance would differ to the macroalgae in a saltwater tank?

what do use for lighting i have an ati cora plus blue plus true atinic and a 10000k t5 bulbs 2 watt bulbs will that work

What type of pipefish and gobys do you have? Looks good! Also do you have videos about your seahorses? I have a 40b seahorse tank with two mating horses and currently taking care of 50+ babys!

Nice video!!!! BTW, I was recently researching why algae are considered "protists" not "plants." With the greatest possible respect sir, I believe it is "1 kind of cell" (only 1 tissue), not only 1 cell. Part of the definition of being a plant is that plants have to have specialized tissues. For example, even mosses that do not have true roots, nor vascular tissue, do have one k ind of tissue for their rhizomes (which only anchor the moss, nutrients are passively absorbed from the soil whereas true roots with xylem would actively set ground water and minerals up the stem of a vascular plant) & mosses have another kind of tissue for the green part & when they make little spore forming structures, that is another kind of tissue. But algae, both the green film algae & the macro algae only have 1 k ind of tissue that; even if it takes different shapes in different parts of the macro algae, it is still all 1 tissue with the same cell type repeated over and over. Please understand, I"m not trying to be disrespectful all, just passing on the information I researched to figure out why everyone calls giant Kelp protists., not plants.

Thank yu

Gahhhhh so many cardinals! I just have my one little Louie!

Love this tank I just purchased a 75 gallon tank for seahorses. I would love to see a livestock list of what you have that is getting along well with the seahorses.

LOOK IN THE VERY FAR RIGHT ITS THE 1:25 "Wacky Waving Inflatable Arm Flailing Tube Man"

Hey I just got some red ogo for my 10gal nano reef. Do you have any tips for this species?

What iron supplement do you use?

If I pick up macroalgae from an LFS that has been growing under a light 24/7 in a refugium, how would you go about weaning that macroalgae down to an ordinary day/night cycle?

I brought myself some Ulva from the black sea last summer , it melted down in a couple of days , I think it was because of the high temperature of my tank , its a fish only with no cooling, at 82 degrees in the hot summer days . did not try any other macro . any suggestions would be much appreciated .

Any recommendations for iron that we can buy in the usa?

Is there any prepared artificial supplement for marine microalgae

Any tips on attaching new macro to the rock?

Is 6 hours off light anuff for these algae ?

Great video. Do you think this would work for a brackish mangrove setup. Something with a salinity range of about 1.010-1.015 perhaps? Cheers!

How do you keep so many Bangai Cardinals without a pair killing the rest?

What type of lighting do you recommend on a planted tank. DOn't plants use a different spectrum from coral?

How your sea horses find the tank ?

What is that green macro algae in the front of your tank called? Would love to get some for my seapony tank

somewhat got it down you make me want to do a video lol

How many liters is it

Do they require the same kind of light as corals?

I am new to this hobby. However, i remodel homes and pools salt/chlorine and oceanography educated back in highschool for all 4 yrs. I enjoy critical thinking to find and search for an easier way. At times it can be curiosity, such as this one. So here is an idea. Why not place the plants in the sump and place a light above it. This way the a refugium is created along with kelp for nitrates elimination the way you have a cleaner aquarium for fish and coral? Am I on to something here 🤔?

How did you attach the ulva lactuca

Hi there I'm running a aqua one 195 using miracle mud and algae only no skimmer. I'm using red sea iron kit but my readings are zero, I'm adding red sea iron but still shows zero. 60ml added in the last week is this normal? I'd thought I would have some kind of reading but seems to be stripping it out as quickly as I put it in. Kind regards Dan

Are they a single celled or a colonial single celled protist?

Hello, maybe you can help me out mate, I just can keep macroalgae alive. after a few days it just turns pale and liquifies.... no damage done but the algae just vanish. water parameters: pH:8.2 mg:1150-1200 Ca:440-460 Kh:8 0.024 sg no3: 5 mg/l po4: 0.3 mg/3 temperature is the same that you'd expect in a reef tank... and I've got no fish that could be munching on it.... I've tried dosing planted tank trace elements and iron... giving it iron tablets by the roots.... nothing works... it just melts away. :(

Ok ...nice work with the macroalgae but ..I could not help notice the (easy to feed)Bangaiis alongside the (hard to keep) pipefish and seahorses. How do u accomplish that? Gorgeous tank btw .

Ok, but how do I get them?

Hi, how often do you have to change the water on this tank?

💜👍

Very interesting. Being a planted freshwater guy, this is very appealing to me. Do corals mix well with macro algaes, and what fish do best with them?

Again an aquarium where pipefish and seahorses live alongside with other fish. I always thought they had no chance to compete for food with other fish, because they feed very slow... How do you manage this?

I have to grow macro algae in a small aquarium for my project. (I have to pick my macro algaes from Marmara Sea. Or buy them from a shop.) Can you tell me how to grow them step by step?

List of algae in this tank?

Wait. Where does Blue Ochtodes fall into? Green, Red, or Brown?

Where do you get your macro?

Cool video man and intresting topic. Think ive got dragons breath growing in my tank from my life rock. Had LR in another tank for 2 years put it in new 9ft tank and its growing bigger every week. If u have the time please check out 1 of my videos to see if it is dragons breath please, thanks man. Keep up the videos ✌️️

Macroalgae isn't one large cell, it's multicellular. Microalgaes can be unicellular, but it you looked at a seaweed under a microscope you could see individual cells

singular: alga ; plural: algae

Uhh... Macro Algae are not "one-cell"/single-celled; I'm fairly certain they're almost all multi-celled.

Its very wrong to say that macroalgae is one large cell, who told you that?

The life of a fish. Is to sit and do nothing.
