More information
Tetra Algizit* provides rapid relief from even the most stubborn algae outbreaks in freshwater aquariums, tackling green, brown and red algae as well as challenging brush and beard varieties. The fast‑dissolving tablets release a highly active ingredient immediately upon contact with water, disrupting the metabolism of the algae, while remaining gentle on fish, plants and beneficial microorganisms when used as directed. Tetra Algizit* does not cloud or colour the water. Simply add one tablet per 20 L of aquarium water and place it in an area with good water movement to ensure optimum distribution. Repeat after two weeks if needed, and maintain aeration (for example with a Tetra APS air pump) while suspending activated carbon filtration, UV clarification and water changes during treatment. Remove dead algae mechanically to preserve water quality, and follow up with nutrient control - reducing phosphate and nitrate values with Tetra EasyBalance - to prevent future outbreaks. For ongoing prevention in small aquariums, consider Tetra Algetten*, or for larger setups, Tetra AlgoStop depot*. Always keep the product away from direct sunlight.

FAQs
What is Tetra Algizit* and how does it work?
Tetra Algizit* is a highly effective algae treatment for freshwater aquariums. It targets even the most stubborn algae types, including green, brown, red, brush, and beard algae. The fast-dissolving tablets release a powerful active ingredient immediately upon contact with water, directly interfering with algae metabolism while remaining safe for fish, plants and beneficial bacteria when used as directed.
How quickly does Tetra Algizit* take effect?
Tetra Algizit* is designed for fastest possible action. It begins working immediately upon dissolving in the aquarium water, with noticeable results often visible within two to three weeks – depending on the severity and type of algae present.
Is Tetra Algizit* safe for fish and aquatic plants?
Yes, Tetra Algizit* is safe for fish and plants when used according to the instructions. Nevertheless, always monitor sensitive species during treatment.
Does Tetra Algizit* cloud the water or alter its colour?
No, Tetra Algizit* does not cloud or colour the water. The tablets dissolve completely and work without leaving visible residues, provided good water movement is maintained.
How should I use Tetra Algizit* in my aquarium?
Add 1 tablet per 20 litres of aquarium water, placing it in an area with good water flow. Avoid using activated carbon, UV filters, or performing water changes during treatment. Repeat the application after two weeks if algae persist.
What types of algae does Tetra Algizit* target?
Tetra Algizit* is particularly effective against red algae, brush algae and beard algae, which are often more difficult to treat. It also works well against common green and brown algae types.
Can I use Tetra Algizit* together with other Tetra products?
Yes, Tetra Algizit* can be used in combination with products such as Tetra EasyBalance (for nutrient control) or Tetra AquaSafe (for water conditioning), but it should not be used with other algae treatments like AlguMin* or AlgoStop depot* at the same time. Allow time between treatments and always follow the label instructions. Wait several days and check water parameters with the Tetra Test 7in1 before starting another treatment.
What is the difference between Tetra Algizit* and Tetra Algetten*?
While both products treat algae, Tetra Algizit* is a fast-acting, intensive treatment suited for acute infestations, including red or beard algae. Tetra Algetten* is a slow-release product, ideal for long-term prevention of green algae. Choose Tetra Algizit* for immediate relief, and Tetra Algetten* for ongoing control.
How can I manage lighting and feeding to prevent algae?
Limit lighting to 8–10 hours per day and avoid direct sunlight to stop algae from overgrowing. Don’t overfeed your fish – leftover food increases nitrate and phosphate levels, which algae love. To control nutrients, use Tetra EasyBalance weekly; it helps reduce excess phosphate and nitrate that promote algae growth.
How do water changes and conditioners help keep algae under control?
Weekly water changes (20–30%) remove nutrients that feed algae. Between changes, Tetra EasyBalance keeps nitrate and phosphate low, preventing unwanted algae outbreaks.
What role do plants and tank cleaning play in algae prevention?
Healthy live plants absorb nutrients and outcompete algae. Remove dying leaves and vacuum waste during water changes. A clean tank with strong plant growth is less likely to develop algae.
How can I treat an algae outbreak safely?
Remove algae manually, then check lighting and feeding. For treatment, use the Tetra anti-algae range. Maintain good aeration and remove dead algae to protect water quality.
