API® pH DOWN pH adjuster effectively reduces pH levels to create a more acidic environment for freshwater aquariums, benefiting both fish and plants when the pH rises too high. The pH scale measures how acidic or alkaline water is, with a value of 7.0 indicating neutrality; values above 7.0 are alkaline, while those below 7.0 are acidic.

Since various fish species require specific pH levels for optimal health, it’s essential to routinely check your water to maintain the appropriate pH range. The pH DOWN pH adjuster is quick to act, clear, user-friendly, and will not cloud your aquarium water. Additionally, being free from phosphates and nitrates, it will not promote algae growth.

Use an API pH TEST KIT to check the pH of your aquarium water. To decrease pH, simply add 1 ml for every 10 gallons of water in the aquarium.

Before applying another dose of pH DOWN pH adjuster, ensure you take another pH measurement.

Be mindful that some fish may react sensitively to pH changes greater than 0.2 within a 24-hour timeframe, so such adjustments should be made with caution.

Thin, sticky, & hi-heat tolerant!
This tape is thin and doesn’t leave imprints on heat pressed apparel! I’ve used it on coffee mugs, koozies, clothing and hats and it adhered well to all of them, didn’t leave behind sticky residue even after 3 minutes of 430’ F it works perfectly.
