2HR Aquarist APT1 Zero
Information
APT Zero allows you to enjoy all the benefits of the ADA approach—unparalleled algae control and the ability to unlock the richest reds in popular plants through nitrate limitation. It should be paired with the use of aquasoil and/or a higher fishload environment.
APT 1 is perfect for tanks with more fish, fewer plants. Also for new tanks (<3 months) with aquasoil. Enjoy comprehensive nutrition without nitrates and phosphates for maximum algae control.
APT Zero contains no nitrates and phosphates, and should be used if you have a fish population that produces adequate nitrates in the tank (specifically, if your tank measures >10ppm NO3 by end of the week with no fertilizer dosing and water change).
How to Use
- Use APT Zero in tanks with fish populations that naturally produce over 10ppm nitrate by the end of the week without fertilizer or water changes.
- Pair with aquasoil or a higher fish load to support plant growth and nutrient delivery.
- Ensure regular water testing to monitor nitrate levels and adjust dosing accordingly.

FAQ
Can APT Zero be used in a tank with low fish population?
APT Zero is best suited for tanks with higher fish loads that naturally produce over 10ppm nitrate. In tanks with low fish populations, nitrate levels may not reach the required threshold, making it less effective.
Is aquasoil required to use APT Zero?
Aquasoil is not required but recommended. Using aquasoil with APT Zero enhances plant nutrition and supports better root development and plant health.
How often should I test nitrate levels when using APT Zero?
Test nitrate levels at the end of each week to ensure they remain above 10ppm. This helps confirm that the fish population is producing sufficient nitrates for optimal performance.

I’ve used APT Zero in my 20-gallon tank with a mix of fish and plants. After two weeks, my anubias and crypts showed much richer red coloring. Nitrate levels stayed above 10ppm, and algae growth has dropped significantly. I pair it with aquasoil and a moderate fish load. Works well for my setup.

The product delivers on the promise of algae control and vibrant plant colors. I noticed a difference in my red stem plants after just one week. My tank has a higher fish population, so nitrate levels naturally stay above 10ppm. I don’t need to dose fertilizers anymore.

Switched from a regular substrate to APT Zero in a new tank with aquasoil. The plants have grown stronger and the water looks clearer. No algae on the glass or on plant leaves. I test nitrate weekly and keep it above 10ppm to maintain results.
