THE2HR AQUARIST APT FIX?APT ZERO Initial

APT FIX 300ml
APT FIX is effective against most types of algae, including black beard algae, blue-green algae, coral-like algae, dust algae, spot algae, and hair algae. It is gentle on shrimp, tropical fish, and aquatic plants, and is broken down by bacteria within approximately 24 hours. It works by binding to the proteins in algae, rendering their cells inactive. The ingredients are activated in water but are rapidly broken down by bacteria, so they do not accumulate in the aquarium long-term. This allows for effective control of various types of algae. APT FIX is broken down within 24 hours, using active compounds that leave no residue in the aquarium.

APT ZERO 300ml
For planted aquariums with few aquatic plants and many fish, we recommend APT ZERO, an all-in-one liquid nutrient supplement that excludes nitrogen and phosphorus. It is also cost-effective, with a 300ml bottle lasting approximately 6 months for a 60cm tank, a 500ml bottle for about 10 months, and a 1000ml bottle for about 20 months. Some aquarists believe that liquid nutrient supplements are unnecessary if using soil in planted aquariums. However, the nutrients contained in soil are unstable. For example, it is unknown how much of each nutrient is present in the soil. Furthermore, soluble nutrients are easily lost through water changes. To promote the health of aquatic plants, we recommend administering liquid nutrient supplements from the initial setup.

Tetra's Initial Stick is a classic solid fertilizer (commonly known as ini-bou) that provides long-term supply of iron, potassium, and organic matter to the roots of aquatic plants. It is suitable for mixing into the substrate during aquarium setup or for top-dressing slow-growing aquatic plants, and is effective in activating bacteria and suppressing algae.
