2HR AQUARIST APT 1 Complete Aquarium Plant Fertiliser

APT 1 replicates APT 3's winning formula without nitrates and phosphates. This gives maximum algae control for new tanks (we recommend all tanks to start with APT 1 for the first 1-3 months), and optimal long term performance for tanks with more fish. This is because fish food and waste already supply phosphates and nitrates.

Example of APT's relative concentration compared with a 50-year old European 'big brand fertiliser'. APT contains 5X the amount of Phosphorus (P) and 6X Potassium (K) per ml.

For optimal results, combine regular fertilisation with a water change routine of at least 25% every two weeks. If algae becomes problematic, increase water change frequency up to 50% and introduce fast-growing plants to help balance the aquarium ecosystem.

Available in convenient 100ml, 200ml, 300ml, 500ml, and 1000ml sizes to suit aquariums of all dimensions.
