Top tips for algae control

Test your aquarium regularly. Especially for waste levels like nitrate and phosphate. This is because raised waste levels can encourage nuisance algae to grow. If the waste levels are high, water changes can help. If the phosphates are still high after water changes, RowaPhos added to your filter will remove more phosphate.

Grow and feed aquarium plants so that they can outcompete algae within a freshwater fish tank.

Increase flow in aquarium to fight against algae. Most live aquarium plants will appreciate a descent flow, whilst most algae likes more still water. If your filters are running slow – perhaps it’s time to clean them. If you don’t have enough flow from the filter alone, you could add another filter or flow pump.

Make sure you are not providing too much light. Try 6 to 8 hours of light a day and avoid placing your aquarium in direct sunlight.

Reducing plastic waste where possible

A 30ml dosing cap is available on request with this product free of charge. We can provide on cap with each bottle purchased. We do not include cups by default to reduce plastic waste. There are many other ways to measure out dechlorinator. For example, a standard teaspoon is 5ml.

Bottle pump available

Another way to easily dose is by using a reusable bottle pump. The dosing pump fits onto every sized bottle of the Aquadip Aquarium Care product range. The riser pipe can be cut once to the size that you need.
Each press of the pump supplies 2ml of liquid and you can dose straight into an area of high flow directly to your aquarium. Click here to add one to your order.
