Our take on the Fritz Complete
Fritz Complete is an 8 fl oz liquid water conditioner for freshwater and saltwater aquariums. It detoxifies chlorine, chloramine and heavy metals in tap water and adds a slime coat agent, so it covers dechlorination and stress protection in one dose. It is a mid-priced conditioner sold mainly through aquarium retailers; the 8 oz bottle treats roughly 240 gallons at the standard 1 teaspoon per 10 gallons, which makes it a reasonable size for small to mid-size tanks.
- Detoxifies chlorine, chloramine and heavy metals in one step
- Includes a slime coat additive, so no separate stress product is needed
- Liquid formula doses easily with the cap
- 8 oz treats about 240 gallons, enough for months on a small tank
- Works in both freshwater and saltwater

Questions and answers
- Is Fritz Complete worth it over a basic dechlorinator?
- If you want one product that removes chlorine, chloramine and heavy metals and adds a slime coat, yes. If you only need dechlorination, a plain conditioner costs less per gallon.
- How much does 8 oz treat?
- At the standard dose of 1 teaspoon per 10 gallons, an 8 oz bottle treats about 240 gallons. That is roughly 24 water changes on a 10-gallon tank.
- Can I use it in a saltwater tank?
- Yes. Fritz Complete is labeled for both freshwater and saltwater aquariums and is commonly used for mixing new saltwater and topping off.
- Does it cycle a new tank?
- No. It conditions tap water but does not add nitrifying bacteria. Use a separate bacteria starter if you are cycling a new aquarium.
- When is the best time to dose it?
- Dose the new water before or as you add it during a water change. Treat the volume of water you are replacing, not the whole tank.
