API Goldfish Success Pack 30ml on Card 2pk
Give a new goldfish tank the best possible start. The API Goldfish Success Pack puts two 30 mL trial-size treatments on one card — Goldfish Protect, a tap water conditioner, and Goldfish Aquarium Cleaner, a waste-digesting bacteria supplement — so a new bowl or starter goldfish tank goes in safe and stays clean while its filter finds its feet.
Key features
- Two goldfish essentials, one card — a 30 mL bottle of Goldfish Protect and a 30 mL bottle of Goldfish Aquarium Cleaner, sized to try both before committing to full-size bottles.
- Conditions tap water — Goldfish Protect removes chlorine and chloramine and helps detoxify ammonia before it reaches your goldfish.
- Supports the biological cycle — Goldfish Aquarium Cleaner adds waste-digesting bacteria that help break down fish waste and gravel sludge while a new filter is still establishing.
- Used together — both bottles are designed to be added at the same time, at each partial water change.
- Trial-sized, not a bulk supply — 30 mL of each is enough to get a bowl or starter tank through its first weeks, not an ongoing monthly supply for a larger, established tank.
What's included, and what you'll still need
This is a two-item starter pack, not a complete tank set-up.
Included: one 30 mL bottle of Goldfish Protect (tap water conditioner) and one 30 mL bottle of Goldfish Aquarium Cleaner (waste-digesting bacteria supplement), both on a single card.
Not included: a tank or bowl, a filter, fish food, a water test kit, and full-size refill bottles for ongoing use once the trial bottles run out.
Specifications
| Product | Size | What it does | Use in |
|---|---|---|---|
| Goldfish Protect | 30 mL | Tap water conditioner — removes chlorine and chloramine, helps detoxify ammonia | Freshwater goldfish bowls and tanks |
| Goldfish Aquarium Cleaner | 30 mL | Waste-digesting bacteria supplement — helps break down fish waste and gravel sludge | Freshwater goldfish bowls and tanks |
Dosage and directions
Add both bottles together at each partial water change, dosed to the volume of water you're adding — check the directions printed on the card for the exact rate for your bowl or tank size. API's guidance is to dose weekly, alongside your regular water change routine, not as a one-off treatment.
Suitable for, and not suitable for
Suitable for: freshwater goldfish bowls and starter tanks, new set-ups, and ongoing weekly water changes.
Not suitable for: marine or reef systems. Not sized for an established, larger goldfish tank long-term — once these trial bottles run out, a full-size bottle of each product is the more economical way to keep dosing every water change.
Care and maintenance
Goldfish are heavy waste producers for their size, whatever tank or bowl they're in. A generously sized filter and a weekly water change routine matter more than any bottle on its own — well-kept goldfish are a genuinely long-term pet.
Common questions
What's actually in the API Goldfish Success Pack?
Two 30 mL bottles on one card: Goldfish Protect, a tap water conditioner, and Goldfish Aquarium Cleaner, a waste-digesting bacteria supplement.
Is this pack enough to fully cycle a new tank on its own?
It gets a new bowl or starter tank through its first weeks safely. It doesn't replace proper filtration — goldfish produce enough waste that filter size and weekly water changes do more of the work than any conditioner.
Can I use this pack in an established tank?
Yes, the same weekly water-change routine applies. At 30 mL each, though, both bottles are trial sized and will run out quickly in a larger tank — most goldfish keepers move to full-size bottles of each product once they're past the trial stage.
Do I need to use both bottles every time?
Yes. Goldfish Protect conditions the new water and Goldfish Aquarium Cleaner supports the bacteria that process waste — they're designed to be dosed together, not as alternatives to each other.
