Aqua-Pics Amazon / Plant GH Conditioner 250g — Single-aquarium GH conditioner for sodium-sensitive fish
Many general hardness conditioners lean on sodium salts to move the number, which is the one mineral that discus, Apistogramma and horseface loaches cope with worst. Aqua-Pics Amazon / Plant GH Conditioner 250g (SKU: 101615) is Aqua-Pics’ low-sodium, phosphate-free answer, a mineral and trace-element powder that raises general hardness (GH) in freshwater aquariums while supplying the magnesium and potassium that plants also need. The dose is one rounded teaspoon, about 8 g, per 20 L of water, stated to raise GH by roughly 7 dGH (125 ppm) per treatment. The 250 g pack is a step up from the trial-size pouch and the natural choice for one aquarium kept on a regular water-change routine.
The minerals it adds help soft-water fish regulate osmosis, the process by which a fish balances salts and water across its gills and skin, which is why Aqua-Pics names discus, catfish, Apistogramma, horseface loaches, angelfish and tetras as the fish it is built for. In a planted Amazon-style tank the same dose doubles as a magnesium and potassium top-up for the plants, so there is no need for a separate mineral fertiliser just for that pair of nutrients. At 8 g per 20 L, a 250 g pack covers about 625 L across repeated doses, which on a typical weekly 20 to 25 percent water change routine spans a good run of months on one display. Stir the measured dose into the change water rather than straight into the tank, and check GH before the next treatment.
Usage & Application
When to Use
- Sodium-sensitive fish: Discus, catfish, Apistogramma, horseface loaches, angelfish and tetras.
- Regular water changes: Replacing the hardness and minerals removed with each change.
- Planted Amazon tanks: Magnesium and potassium support plant growth as well as fish health.
- Soft tap water: Mains supplies with little natural hardness that need a mineral floor set.
Dosing & Administration Guide
- Standard dose: 1 rounded teaspoon (about 8 g) per 20 L of water.
- Expected rise: Approximately 7 dGH, or 125 ppm, per treated dose.
- Dose into change water: Dissolve before it goes back into the aquarium.
- Retest first: Confirm GH before repeating, rather than dosing on a fixed interval alone.
