Guard 300ml – algae control

Guard 300 ml is a freshwater aquarium treatment for keepers who want to prevent algae before it appears rather than remove it afterwards. It targets phosphorus, the nutrient that algae depend on, and is dosed in 5 ml caps, so the amount added to each tank is easy to control.

Why it matters

• It keeps excess phosphorus from accumulating in the tank, whatever compound it is in.
• Phosphorus often binds with other elements and becomes unavailable to plants, which is one common route to algae growth. The product addresses this by reducing the surplus.
• It keeps plant leaves clean, which supports photosynthesis and, according to the manufacturer, speeds up plant growth.
• The starting dose is 2 caps (2 x 5 ml) per 60 l, and the manufacturer states that one bottle lasts about 6 months.

What it works with

Guard is intended for freshwater aquariums, and the dosing is calculated per 60 l of water, so the volume of the tank determines how many caps to use. It fits planted freshwater setups where algae control and plant health are both priorities. If too much is added, the water may turn cloudy for a short time.
