Chaetomorpha Chaeto Linum Marine Macro Algae

The  Chaetomorpha / Chaeto marine macro algae love the light, as more as you provide as faster it will grow.


This Chaeto algae species is not palatable and we would not recommend to add it to your fish tank display. As especially Tang Fishes might try to eat it, but can't digest it.

Chaeto algae species are not invasive and they won't attach themselves. A great choice for the refugium for nutrients export.

Whitish parts of it should be removed as they are decomposing. But Chaeto is a very stable macro alga, so this should hardly happen.

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

Please note
Our macro algae are from fish free macro algae tanks, although we use sometimes 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 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 macro algae will be thoroughly dipped in a professional solution to deactivate hitchhikers as good as possible before posting. 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 Chris on 21/02/2018

I bought some of your Chaeto which sunk to the bottom of my refugium. Now most of it is floating with air bubbles on it, I'm wondering if that's what it does when it starts to grow?


It could be a sign of having micro bubbles in your system maybe. Simply shake the chaeto to remove the bubbles, and attach it to some piece of rock or similar to keep it down.  Maybe you can find as well a way to reduce the micro bubbles in your sump? 

questions Ben on 13/12/2017

Can I use this in my fish tank, as I don't have a sump?


Hello Ben. Yes, sure you can use Chaeto in your Tank Display. It won't attach itself and is therefore safe to use. Although we would recommend more prettier macro algae to use in the Tank Display. Especially like the Blue Ochtodes, it looks much nicer and fishes love to nibble on it. It will attach itself, but it isn't spreading like Caulerpa macroalgae and without possible problems, as we described in the Caulerpa CASE,

Maybe you can use it in your overflow instead when you have there light too?

BTW: When we had it in our private tank our Tang tried to eat it and as he couldn't digest it, he was for a day a bit uncomfortable.
