Product details
Description
Transform your freshwater planted aquarium into a lush, vibrant underwater ecosystem with a targeted macronutrient solution designed to optimize aquatic plant vitality. In planted aquariums, phosphorus frequently becomes the limiting factor that halts growth, leading to stunted development and dark green or discolored foliage.
This specialized liquid supplement delivers a precisely calibrated concentration of potassium phosphate directly to your tank inhabitants without introducing unwanted nitrates into the water column. By separating nitrogen and phosphorus dosing, hobbyists gain complete control over individual nutrient parameters, tailoring fertilization precisely to unique tank demands.
The advanced formula accelerates root development and overall leaf expansion while remaining entirely safe for delicate freshwater fish, bottom-dwellers, and sensitive invertebrates like shrimp. Enjoy peace of mind knowing your aquatic garden receives scientifically balanced nourishment engineered to promote robust health without triggering unwanted algae blooms.
How to use
- Beginner Dose: Use 2.5 milliliters (about half a capful) per 80 liters (20 US gallons) once or twice a week, or as needed in response to signs of phosphorus deficiency such as stunted growth or dark green leaves.
- Keep target phosphate levels between 0.15 to 1.0 milligrams per liter.

was skeptical
was skeptical about adding extra chemicals to my planted tank since my shrimp are pretty sensitive but this potassium phosphate stuff worked without causing any sudden algae outbreaks. my crypts and stem plants were looking dark green and stuck in growth before. started dosing half a capful for my setup and leaves are actually expanding now. pretty happy with how it turned out.

stocking up for tanks
ordered two bottles this time since I maintain multiple freshwater planted aquariums at home and phosphorus is always the limiting factor that halts growth in them. keeping separate bottles for nitrogen and potassium phosphate gives me full control over unique tank demands instead of mixed NPK. delivery was fast and the 250 ml size lasts decent time. good stuff.

delivery delay but product good
the courier took an extra three days to deliver which was annoying because my tank was running low on macro nutrients and plant growth had slowed down. the bottle itself was packed okay though. once I started using it once a week for my planted tank the dark green discolored foliage cleared up nicely. glad it does not add unwanted nitrates into the water column. works fine.
