Fritz Complete (16 oz)
A full-spectrum challenger to Prime: removes chlorine, neutralises chloramine, detoxifies ammonia and nitrite and even nitrate, and adds a slime coat. Excellent, if less famous and pricier per ounce.

- +Also gives nitrite protection, detoxifies nitrate, and adds a slime coat
- +Concentrated at 5 mL per 10 gallons and does not affect pH
- +Shrimp safe and plant safe, and gentle on biofilter
- −Pricier per ounce than Prime and less concentrated, so not the cost-per-gallon leader
- −A smaller, newer brand with far fewer reviews than the API and Seachem staples
This is Fritz Complete, a full-spectrum challenger to Prime: it removes chlorine, neutralises chloramine, detoxifies ammonia and nitrite, even detoxifies nitrate, and adds a slime coat, working instantly at 5 mL per 10 gallons. It is excellent, if less famous and pricier per ounce.
- Keepers who want full-spectrum protection including nitrate
- Water changes and cycling, thanks to ammonia and nitrite detox
- Fresh and saltwater tanks, shrimp and plants
- Buyers chasing the absolute lowest cost per gallon, where Safe wins
- Anyone who wants the longest track record, where Prime leads
- People who only need plain dechlorination, where cheaper options fit
We separate what the maker claims from what independent sources confirm, what owners report, and where we are drawing an inference. We do not bench-test products.
- Removes chlorine and chloramine, detoxifies ammonia, nitrite and nitrate
- Adds a slime coat; 5 mL per 10 gallons; no pH impact
- Fresh and saltwater, shrimp and plant safe
- Full-spectrum like Prime, and also addresses nitrate
- Pricier per ounce and less concentrated than Prime
- Very well rated; a smaller, newer brand with fewer reviews than API and Seachem
- A genuine full-spectrum alternative to Prime, with nitrate detox as a bonus; the trade-offs are price per ounce and a shorter track record
Concentrated at 5 mL per 10 gallons but pricier per ounce than Prime, so not the cost-per-gallon leader. Worth it if you value the added nitrate detox and slime coat in one bottle.
- Higher cost per gallon than Safe or Prime
- Assuming ammonia detox is permanent, when it is temporary like Prime
- A shorter brand track record than the staples
We do not lab-test the chemistry; we relay the manufacturer's stated figures. We give gear and method guidance only, not livestock or disease advice; route fish-health questions to a veterinarian or an established authority. For a serious ammonia emergency or a sick tank, consult a veterinarian or an established authority alongside conditioning the water.
It is also full-spectrum but additionally detoxifies nitrate and adds a slime coat. It is pricier per ounce and less concentrated, so Prime and Safe still win on cost per gallon.
Like other detoxifiers it is temporary, so redose during an emergency until the source is fixed, and consult a vet for a serious spike.
Yes, it is rated for both, plus shrimp and plants.
