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.

Works
Size: 8.5"x11"
Works great for sublimation. Get plenty of sheets. Great value for the price. The paper is pretty thick and seems to hold a good amount of ink without smearing.

My go-to sublimation paper for crafting
Size: 8.5"x11"
I've used several sublimation papers, and this one has worked really well for my crafting projects. The colors transfer bright and vibrant, and the images come out crisp with good detail when using the proper sublimation printer and ink. The paper feeds smoothly through my printer and feels like a good quality weight—not too thin and not overly thick. I've used it for tumblers, keychains, and other sublimation projects, and I've been happy with the results. I also appreciate getting 110 sheets in one pack because it lasts a while, especially when working on multiple projects at once. Overall, this is a reliable sublimation paper that gives consistent results and is great for crafters or small business owners.
