Aqua-pics Goldfish Gh Salt 20kg — Wholesale-size GH conditioner for commercial goldfish operations
A commercial goldfish grower, wholesaler or large retail holding facility works with tank volumes measured in the tens of thousands of litres, and dosing that scale from small retail pots is not a realistic option. Aqua-pics Goldfish Gh Salt 20kg (SKU: 102252) is the largest size in Aqua-Pics’ phosphate-free GH conditioner range, the same mineral and trace element blend with added potassium sold in every other pack size, supplied as a 20 kg bulk quantity. It raises general hardness (GH) using calcium, magnesium and potassium rather than plain salt, supporting the osmoregulation that underpins goldfish health across a volume of water well beyond a single hobby aquarium. The 20 kg size is intended for commercial and wholesale use rather than a home tank, where the running cost per litre of water treated matters more than convenience in a small pot.
The dose remains the same 1 rounded teaspoon, about 8 g, per 10 L of aquarium water, raising GH by roughly 12 dGH (214 ppm) per application, scaled up for weighed dosing rather than teaspoon measures at this volume. A 20 kg bag holds about 2,500 of those doses, equivalent to roughly 25,000 L of treated water across its life, enough to maintain a large holding system, a commercial pond network or a wholesale fish room through an extended operating period. Dosing is typically tied to water-change or top-up schedules across the whole system, and the phosphate-free formula matters more at this scale, since a 20 kg bag of a phosphate-based salt dosed regularly could drive a substantial algae load in a large system. The same product is available down to 150 g for keepers who need only a trial quantity.
Usage & Application
When to Use
- Commercial goldfish operations: Growers, wholesalers and large retail holding facilities.
- Large pond networks: Multiple outdoor systems dosed from one bulk supply.
- High-volume water changes: Systems where tens of thousands of litres are treated regularly.
- Reducing per-litre cost: Operations where buying in bulk materially lowers running expenses.
Mixing & Application Guide
- Weigh accurately: Use a scale rather than teaspoon measures for bulk dosing.
- Pre-dissolve in bulk containers: Mix a weighed batch into water before introducing it to the system.
- Dose to measured volume: Calculate the actual system volume before scaling the dose up.
- Monitor across the system: Check GH at several points in a large system, not just one tank.
