Bag Plus – 8 cartridges for reducing the pH and GH of water

This set of eight sachets is meant for aquarium keepers who want to lower pH and GH without dosing liquid preparations. Each sachet goes into the filter or near the filter outlet, so the water passes through it continuously. The manufacturer states that the sachets bind positively charged compounds responsible for water hardness, which is the basis of the pH and GH claim.

Why it matters

• Two filtration methods in one medium: the sachets contain both biological and chemical components, which the manufacturer says work together to remove nitrogen and phosphorus compounds and other unwanted substances.
• Activated carbon: binds and neutralises heavy metals, which the manufacturer says also helps keep the water fresh.
• Organic carbon content: supplies a food source for beneficial bacteria, which feed on organic pollutants in the water.
• Dosing by volume: one sachet is assigned to 60 L of water, so the amount is easy to match to tank size.

What it works with

The sachets fit cascade, bucket and internal filters, and can also be placed in the aquarium at the filter outlet. The manufacturer notes that higher water flow speeds up and improves their action, so placement where water moves strongly is preferable. Before first use, rinse each sachet in running water and shake it under the stream 20 times.
