    Chaetomorpha Chaeto Linum Thick


    Chaetomorpha or often just called Chaeto algae is a perfect nutrients export marine macro algae species. Often placed in the the refugium it the most popular macroalgae used for nutrients export, as it is a non-invasive and fast-growing macroalgae, which is very easy to care for. This Chaeto algae species is not palatable, but the main purpose it does quite well, reducing the nitrate and phosphate levels in the aquarium water.  It is the most stable Chaeto species available, which means it can handle even low nutrient levels of phosphate and nitrate for some time.

    We have a palatable Chaeto species as well HERE and the faster growing Chaeto species HERE



    Chaetomorpha Chaeto Linum 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 Chaetomorpha / Chaeto marine macro algae loves 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 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 live algae.

    If the macroalgae is not growing as expected a special formulated fertiliser for the marine aquarium can help to improve the growth of the macroalgae. Please find a selection of supplements for the marine aquarium HERE  

    Chaetomorpha Linum Variations
    Chaeto Linum - or often called Spaghetti Algae - are a loosely entangled group of macro algae species which are non-invasive with unbranched filaments usually between 3 and 40 cm  long.  The colour of it is varying between dark green to bright or yellowish green. It occurs in various diameter sizes ranging between 0.2 - 2.5mm.

    We have a few different Chaetomorpha Linum species available but classify this non-palatable macro algae Chaeto mainly in a very thick Chaeto group, which grows medium fast but is therefore more tolerant to low nutrients in the water and where nutrients remover like Rowaphos, Carbon, Nitrate remover or other water polisher are used. and a medium thick Chaeto group which grows much faster and is therefore our recommended choice for nutrients removal. As it grows very fast it will need sufficient Nutrients to stay stable and might suffer or die off when necessary nutrients ( especially Nitrate and Phosphate ) are very low or where nutrients remover like Rowaphos, Carbon, Nitrate remover or other water polisher are used. If you prefer one of them please let us know. We recommend for Chaeto as well to maintain good Magnesium levels and dosing of Iodine and Iron.

    Please note
    Our macroalgae 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.
