Envii Aquarium Equaliser - Aquarium pH Balance & Controller, Raise pH Up & Down and Buffers KH & GH in Fish Tanks, Ammonia Remover for Aquariums Treats 500 Litres of Water

Impossible to over dose the tank! Couldn't get my water right in my tank for ages used this! tested water next day and it was perfect every time I Warter change I use this stuff and have had no issues with nitrates carbon or alkaline since would recommend only down side is tanks a tad cloudy for a few hours to a day

​I use Envii Aquarium Equaliser across all three of my setups, and it has become my go-to "insurance policy" for water stability. My tanks are all very different, and this product handles each of their unique needs perfectly: ​For my 57L Fluval Flex (Apple Snails, Gourami & Shrimp): This is where I find it most essential. Apple Snails need consistent mineral levels for healthy shell growth. The Equaliser ensures the KH and pH stay stable, preventing shell pitting and keeping the snails thriving alongside the Gouramis. ​For my 45L High-Bioload Planted Tank: With a lot of plants and a high bioload, the water chemistry can naturally shift. This product "equalises" everything, keeping the foundation solid so my Oase ScaperLine soil can do its job without the risk of a pH crash. ​For my 30L AquaEl Shrimp Cube: Stability is life or death for shrimp. Using this during water changes gives me total peace of mind that I’m not shocking my colony with fluctuating parameters. ​Why it’s a 5-star product: ​Safety Net: It provides a vital buffer that prevents dangerous pH swings. ​Easy to Dose: The powder dissolves quickly and doesn't cloud the water. ​Versatile: It works just as well for heavy-waste snails as it does for sensitive ornamental shrimp. ​If you run multiple tanks with different inhabitants, this is the easiest way to ensure your water chemistry remains professional-grade.

Good for all fish, but for snails and shrimp is a no go they all die lost like £50 worth of snails and shrimp when using this. So I'm not buying invertebrates

Hasn’t killed my fish yet so must be good

I like this product as it easy to apply and apparently you can't over dose the tank. My only issue is it doesn't fully dissolve some times and you get residue left over. If you've got a substrate then you won't see it but where your tank is bare then you might see the residue.

Ok for money

Thanks works great very easy to use just put it straight in the tank lovely water clarity fast delivery good value for money

made the water very cloudy, even after 48 hours. Did not see any changes in water parameter. Had to use API ACCU-CLEAR to make the water clear later.

Perfetta per regolare il PH di un piccolo acquario. La polvere si scioglie bene e non danneggia i pesci

Sehr gut

J avais une eau pas trop claire 3 cuillères et quelques heures après une eau magnifique 👌👌👌

Todo perfecto

El agua queda bastante cristalina, funciona bastante bien en conjunto con el liquido de la misma marca, clarificador de agua. El nivel de PH es increiblemente estable. Los peces, felices y sanos.
