Tetra Easy Balance, 100 ml is a product for maintaining water parameters in a freshwater aquarium. According to the description, its combination of active ingredients keeps the water balanced for several months and lets you extend the intervals between water changes. It stabilises carbonate hardness (KH) and pH for up to 6 months, naturally reduces nitrate and phosphate, and adds useful vitamins and minerals for fish and plants. The improved formula contains an optimised mineral blend. The dose is 2.5 ml per 10 l of water, so the 100 ml bottle treats 400 l.

- Minerals and vitamins. For fish and plants.
- Simpler upkeep. Water changes can be less frequent.
- Saves water. Less tap water used.
- Simple dosing. 2.5 ml per 10 l.
Cons and what to watch
- No dosing interval. The dose is given, but not how often to add it.
- The promise of skipping monthly changes is risky. Water changes remove more than just nitrate.
- No ingredients. The active substances are not disclosed.
- Freshwater only. Not suitable for marine tanks.
- Not a conditioner. It does not neutralise chlorine in tap water.
How to dose
Work out the dose from the tank volume: 2.5 ml for every 10 l of water. A 60 l tank, for example, needs 15 ml. The card does not give an interval, so follow the instructions on the pack. Add the product where the filter outflow is strongest so it spreads quickly. Keep treating fresh tap water with a conditioner at water changes, such as Tetra AquaSafe.
Can you skip water changes?
The manufacturer says the product removes the need for monthly partial water changes. But water changes do more than lower nitrate: they remove organic matter, fish growth hormones and other build-up that home tests do not measure. It is more sensible to use Easy Balance to make water changes smaller and less frequent rather than to drop them entirely.
Monitoring parameters
To see whether the product works in your tank, test the water regularly. A handy option is Tetra Test 6in1 strips, which show KH, pH, nitrate and more. If nitrate keeps rising despite the product, check whether you are overfeeding; see aquarium fish food: how to feed.
Similar products
Rikka Aqua Balance does a similar job. If the water is cloudy, you need a different type of product, such as JBL Clynol.
Who benefits most
The stabiliser is useful if your tap water is soft with low KH, where pH crashes easily, and if you go away and cannot change water regularly. In heavily planted or heavily stocked tanks, KH control is especially important.
New tanks
When setting up a new tank, the priority is to colonise the filter with beneficial bacteria and not rush the fish. A parameter stabiliser can be used once the tank has settled into a stable routine. More in aquarium for beginners: what to buy and how to set it up.
Storage
Keep the bottle tightly closed in a cool, dark place out of reach of children. Do not let it freeze.
Who it suits
Tetra Easy Balance suits owners of freshwater aquariums who want to stabilise KH and pH and make water changes less often, while monitoring the water with tests. Other products are in the fish medicines and water care section.
Verdict
Tetra Easy Balance is a KH and pH stabiliser for freshwater aquariums that, according to the description, reduces nitrate and phosphate and adds minerals and vitamins, with 100 ml treating 400 l. The downsides are that no dosing interval is given, the promise of skipping monthly water changes is risky, the ingredients are not disclosed, and it is not for marine tanks.
