Ulva Lactuca - Official Algae of the Year 2015

Light
These macro algae like the light but is fine with medium strong light conditions too.

Palatable
Very palatable and a great natural source for your fishes etc. Our tang loves it, so keep some algae for example in the sump to let it grow back again.

Attaching
As it eventually will attach itself to rock after a long time, we recommend to start with to glue it on a piece of rock to keep it in position. It is very easy to trim by just removing the excessive algae. It forms smooth discs and grows in larger chunks, which can attach themselves to rock etc.

Trimming
Clear parts of it should be removed as they are decomposing.

Treatment
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
It is often known as Sea Lettuce and popular as a salad etc. But we sell these algae just to use in the marine aquarium!

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 Adrian on 04/09/2018
Question: 

Can I keep any algae in quarantine Tank when using copper based solutions? Would there be problem if I can then moving to a sump or main reef tank as food for tangs?

Answer: 

Hi Adrian.


Thank you for your message and I am sorry for the delay, we had unfortunately a problem with our question module.


I hope it still might help you. Although we never used copper as our algae tanks are fish free we received this question earlier and got feedback from our customers too.


From what we know we would not recommend to use macro algae in a copper bases solution. At a very low concentration copper acts as a micro-nutrient, which supports some physiological activities of the algae, but in higher concentrations it can affect the algae growth and the photosynthesis, hence damaging some algae species.


Customers who used it for a short time didn't experienced any problem with it though and explained the slower growth with a different used lighting.


Kind regards


Manfred - Livealgae UK

Shop owner reply (Oct 18, 2018):
Hi.\r\n\r\nI a,m sorry to hear this.\r\n\r\n\r\nUnfortunately, this algae is very palatable for herbivore fishes, like Tangs. We recommend therefore to place it in an area they can\'t reach or to place it in the sump, to let it grow, and feed it time to time to the fishes.\r\n\r\nPlease contact us, and we will find for sure a solution.\r\n\r\nKind regards\r\n\r\nManfred\r\nLivealgae UK
