Ochtodes Sp. Marine Macroalgae

Premium Marine Macro algae for the Planted Reef Display Tank & Refugium for sale on Live Algae UK.
Your 1st choice for clean Marine Macroalgae from Fish & Copper free tanks since 2014.

The Ochtodes macroalgae species will arrive at yours more brown looking, which is completely normal for it. As this macroalgae changes its colour once we take it out of the water and it comes in contact with air.
It will turn back to blue/purple normally within 1-2 days once back in the tank and adjustment to the new water and light environment.

The colouration of the Blue Ochtodes macroalgae will vary between purple to blue, depending on what light spectrum and light intensity will be provided.  Less light will let it turn more deep blue.

As it is quite a fragile macroalgae species we will add a bit more for you than you order to account for any damage in transit or for small break ups.
This macro algae will though easily attach itself together again and to rock or similar. Please just leave it therefore in an area without a current but good light.

The Blue Ochtodes macroalgae prefers good light, but not too much. Its deep blue colour is best to reach with a 6500k-10000k light. With direct sunlight or out of the water it will turn brown.  When you receive these algae it will look brown,  but once back in the marine water it will get its colour back, varying in blue / purple shades, depending on what kind of light and how much light the Blue Ochtodes gets.

The whole macroalgae is very tasty for herbivore marine fishes, like the Foxfish, Tang species etc. Therefore it is recommended to keep this marine algae in a safe area for a reserve until you like to offer it as additional food to your fishes.

This algae will attach itself when left for example on the rock for a few days without movement. Keep an eye on floating bits of it in your tank as they will do the same when they get the chance too.

Whitish parts of the Ochtodes macroalgae should be removed as they are decomposing.

Like for most marine macroalgae a higher level of Nitrate and Phosphate, in addition to the supplement of Iron, Magnesium and Trace elements will improve the growth of this marine algae.

This marine algae can be either placed in the Refugium where it would need an enclosed space or in the marine Display Tank.

Please bear in mind that the dense structure of this beautiful live algae makes it much easier for hitchhikers to hide within the algae and although we dip all macroalgae before posting in a professional solution, some hitchhikers  may survive this. 
If you don't want them please inspect the macro algae very closely before adding it to your tank or keep them in a  quarantine tank or similar for the start.

Our macroalgae are from fish free macroalgae tanks, although we use pictures for demonstration purposes only which will include fishes, seahorses and or corals. 
We do our best to quarantine, treat and remove any unwanted hitchhikers, parasites etc from our macro algae but we can not guarantee that the algae are completely free of anything unwanted, not limited to Copepods, Rotifers, starfishes etc. This is simply because that sometimes eggs, spores, etc can remain viable but not visible and hitchhikers can still stay hidden, especially in dense algae structures, despite our strict quarantine efforts. 

All macroalgae will be thoroughly dipped in a professional solution to deactivate hitchhikers as good as possible before posting. But still inspect your algae on arrival closely. 
If you don't want this, please send us a message together with your order.

We highly recommend nonetheless that you properly quarantine anything new before adding it to your marine tank.

We aim to offer you the healthiest and best quality macro algae on the market, therefore, all of our macro algae comes with a 100% Satisfaction Guarantee.

questions Katy on 10/03/2020

Hi, this is my first time ordering from you and I've been wanting to find blue Ochtodes for quite some time. I've hardly ordered any algae before apart from the red the ones that have 'grapes' on them which make a mess then just disappear. Also chaeto which again by the time the fishes picks at the strands and they are floating around the machine getting stuck in my gyre. I just need some idea of how to tie every bit down to something in my tank while looking nice and still letting it grow. how would my maxspect rsx200 lights cope with itand t deal with trying to make it thrive?


Hi and hank you for your message.

Ochtodes will attach itself very easily. We recommend for a best start to just super glue it to a piece of rubble/rock and let it grow or to place it on some rock and leave it in an area with very low flow but good lighting. It will normally attach itself within 2-3 days.

It is btw a quite fragile algae and better placed therefore in an area with not too much flow but good lighting especially for the start.

It's colours will depend on how much light you provide. Deeper blue when the light is just medium strong to a lighter blue/violet when it gets more light, what we supply.

Should it turns more grey/blue it is too much light for it. As you mentioned before that some fish where picking on your previous macro algae be aware that the Ochtodes is a delicatese for a lot of herbivore fishes, especially Tang species.

Hope this helps.

Kind regards

questions Rob on 16/07/2019

I know it can be set-up/equipment dependant, but can you suggest a ball park figure for lighting, that will give most macro algae a good chance of growing? I'm running AI prime HDs on my tank and there are sooo many setting available that it becomes confusing.

Thank you for any help/advice. Kind regards Rob....


Hi Rob.

The AI Prime's are a fantastic choice, you won't have a problem with them. As I don't know your tanks size nor how close you have them over your tank it is hard to say at what percentage you should have them running. But regards the LED usage : The blue light will penetrate deeper into the water, so this is good when you have the algae at the bottom. I would as well recommend a good amount of red light ( percentage like blue ) when it doesn't get to violet for you, and around 10-20% less for green. White depending on your taste, but like blue this will be the main light they will use. UV a bit  :) Hope this makes sense.

Kind regards

questions Marie L. on 15/05/2018

Hello. I received last week the algae, it looks really nice. But the colour looks more pink in my tank. My water parameters are good. I have around 5 Nitrate and 0.03 Phosphate. How do I get a more blue colour please?


Hello Marie. Thank you for your question and we are happy that you like the macro algae. The colour of the Blue Ochtodes depends of the light you provide. We have best experiences with full spectrum lighting, around 6500k. When it gets direct sunlight the algae tends to become more purple. Although the algae likes good light it will show a deeper blue colour when it gets a medium strong light. If you have any further questions don't hesitate to contact us.

questions Tom on 13/03/2018

Do I need to glue it, or how will it stay in the bottom of my tank?


This macro algae will attach itself within 2-3 days when it gets good light to rock etc.

We recommend to leave it for this time on a small piece of rock or similar in an area without strong current.
If you don't have such an area in your aquarium use some rubber band or place in-between some rockwork to hold it in place until it has attached itself.

We don't recommend just to place it on a fine sandbed, as it needs something to attach itself to stay in place.

We hope this helps.

Kind regards

There is no regrets with this purchase. It looks superb and came in really good condition. It's been in my tank for a few days now and it is showing no signs of decay. Really happy with it. The water it came in too was crystal clear too

The service is super too, really quick and to a high standard

Only a small item which looked good but died after a couple of days despite the water parameters being in spec (tested regularly?
Shame because it looked nice in the photos.

Shop owner reply (Oct 29, 2019):

We are sorry to hear that you have experienced a problem with the Ochtodes macro algae.
This macro algae can be sometimes tricky but once established it is an amazing algae species.

As you have ordered the smallest size it is a small culture but still a perfect value to start with this algae species in your tank.

Of course we guarantee with our full Satisfaction Guarantee on arrival the best quality possible, but once they are in a new environment the water conditions can be very different for them.

We are always there to help, especially when there is a problem so if you like please contact us with your current water parameters, as off Salinity, Nitrate, Phosphate, Magnesium, PH and Alkalinity plus how long your tank is already running and what light ( intensity and light colour ) and we will try our best to figure out together with you why it didn't flourished in your tank.

Kind regards

This algae is almost 'hypnotic' for Copepods.

I keep a nano for live food cultures with no lamp. Nothing is turning white or dying, there is zero decline of the algae, it arrived about two weeks ago. I added lots and lots of nutrients to the water-column in preparation for receiving the algae but the lamp I ordered just did not show up fast. The algae is beautiful, and it is already growing.

I keep a nano for culturing Copepods and they were running/dancing around the glass in thick density, so I found it appropriate to add some kind of decorative macroalgae to house them. Besides the Copepod culture, the nano contained only 1liverock, rotifers and pebble, only a very very soft current for the zooplankton to inhabit the space without problems.

Only 1/3 of the Copepod population remain on the glass now, the rest seem so happy with the Ochtodes that I highly recommend this algae for similar needs.
