Aqua-pics Goldfish Gh Salt 250g — Mineral conditioner that keeps GH stable for a goldfish tank
A goldfish tank on tap water or rainwater can sit well below the general hardness (GH) a goldfish needs to regulate its own body fluids properly, and that shortfall gets worse every time old water is swapped for fresh. Aqua-pics Goldfish Gh Salt 250g (SKU: 101618) is Aqua-Pics’ phosphate-free GH conditioner, a blend of minerals and trace elements with added potassium that restores the hardness many town supplies lack. Rather than adding plain salt, it supplies the calcium, magnesium and potassium goldfish rely on for osmoregulation, contributing to the fish’s general health and longer life. The 250 g pack is the standard retail size in the range, a step up from the 150 g trial pot and sized for a household running one or two goldfish tanks through a normal maintenance cycle.
The dose is one rounded teaspoon, about 8 g, per 10 L of aquarium water, which raises GH by roughly 12 dGH (214 ppm) in a single application. A 250 g pack holds about 31 of those doses, enough to carry a 20 to 60 L goldfish tank through months of routine top-ups rather than a single treatment. Dosing after each water change is the usual pattern, since fresh tap water or rainwater brings the tank back down to its original low GH every time. Because the formula is phosphate-free, repeated dosing does not add phosphate to the system the way some hardening salts do, which matters in tanks already prone to algae. The same conditioner is sold in five further sizes up to 20 kg for keepers with more than one tank to maintain.
Usage & Application
When to Use
- Soft tap water or rainwater: Supplies that leave GH too low for goldfish.
- Scheduled water changes: Replacing GH lost each time water is removed and refilled.
- Household goldfish tanks: A 250 g pack matched to one or two tanks on a regular routine.
- Stocking checks: Confirming hardness before adding new goldfish to an established tank.
Mixing & Application Guide
- Dose by teaspoon: One rounded teaspoon, about 8 g, per 10 L of tank water.
- Pre-dissolve: Mix the dose into some tank water first, then pour it in gradually.
- Confirm with a test kit: Check GH rather than assuming the standard dose is always needed.
- Repeat with water changes: Redose each time a portion of the water is replaced.
