API pH Down 4 oz

The Reliable Way to Balance Your Water

High pH levels can be a major stressor for freshwater fish, leading to poor health and faded colors. API pH Down is a specialized liquid treatment that allows you to gradually and safely lower the pH of your aquarium water to the ideal range for your fish.

Key Benefits for Your Aquarium:

• Algae-Conscious Formula: Many pH adjusters are loaded with phosphates, which act as "fertilizer" for unsightly algae. API pH Down is 100% phosphate-free, giving you a more acidic environment without the risk of green water or hair algae.

• Fast-Acting & Effective: The liquid formula disperses rapidly, making it much easier to use than powders or slow-dissolving tablets.

• Safe for Fish & Plants: Designed to be gentle on aquarium inhabitants. When used as directed, it is completely safe for community fish, sensitive species, and live plants.

• The "Mid-Size" Advantage: This 4 oz bottle is the perfect size for the standard home aquarium, treating up to 1,175 gallons (4,448 L).

When Should You Use pH Down?

• Your tap water is naturally "hard" or alkaline (pH above 7.6).

• You are keeping "soft water" fish like Betas, Angelfish, or South American Tetras.

• You are trying to induce breeding in species that require lower pH levels to spawn.

Application Instructions:

1. Test: Use an API pH Test Kit to determine your current level.

2. Dose: Add 0.5 ml (approx. 10 drops) for every 10 gallons (38 L) of aquarium water.

3. Wait: Let the water circulate for several hours.

4. Re-Test: Check the level again. Pro-Tip: For the safety of your fish, never adjust the pH more than 0.2 units within a 24-hour period.
