Opposite to the beauty of wanted macroalgae in the marine tank, unwanted microalgae - so-called nuisance algae- can become a real nightmare for aquarists.
To identify them is a task which is with some research normally done quite quickly, but to get rid of them can take weeks if not months.
From our experience, we want to give you one possible guideline to get rid of these unwanted pest algae in your marine aquarium, to bring back
the enjoyment of this fantastic hobby.
We know that there are very different approaches, so feel free to add your comments and ideas below. This guide will concentrate on the general approach to this problem and is therefore much shorter and more focused written.
Please have a look at our Introduction and future articles when you like to dig deeper into this topic.
Nuisance Algae - Why do they grow in your tank?
The basis for the growth of algae in your tank is the existence of Phosphate and Nitrate in the water ( we neglect other chemicals algae might need as trace parts, to keep it simple here),
plus a sufficient lighting.
The main reason how phosphate gets into the marine tank is with the food, especially by frozen food and some phosphate-rich flake food products.
In short words... comes mainly from the excretions of your livestock and decomposing material.
The usage of dry or older "liverock" can cause your tank to cycle again, and will normally cause an algae bloom, which takes normally a few weeks.
Even larger movements of existing liverock in your tank can cause a new algae bloom.
How to get rid of nuisance
Do you have any question we can help you with?
As an aquatic algae farm, we don't have a public shop to visit unfortunately but we are happy to post all our macro algae species within the UK for free to you.
And we are sure you will like your new macro algae addition once received.
You can register your interest on the algae page you are looking for to get an email once it is back in stock or stay informed via our Newsletter, and or to follow us on Facebook, as we will first inform there when our algae are ready to sell again, or when we received new
When a macro algae species sells well we have sometimes to take it out of the sale as it will need time to regrow again.
The time for this will vary, as some macro algae species will grow very slow, whilst other - especially various Caulerpa marine macro algae species grow quite fast.
