Water conditioners for freshwater aquariums
Preparing the water is essential when setting up an aquarium and during water changes. Our aquarium water conditioners include JBL Biotopol, Sera Aquatan and Easy-Life AquaMaker, with different formulas and packaging.
Why use a water conditioner?
Depending on the formula, a conditioner can help neutralize chlorine, chloramines or certain heavy metals present in tap water. Check the substances actually covered by the chosen product and the manufacturer's recommendations.
How to choose the right conditioner?
- Aquarium type: freshwater, saltwater, goldfish, shrimp or other sensitive species according to the instructions.
- Usage: preparing new water or adding directly to the aquarium, depending on the product.
- Concentration: compare the actual dosages, not just the price of the bottle.
- Compatibility: do not combine products without checking their instructions and precautions.
Properly preparing a water change
Measure the volume of water to be replaced, check its temperature and use the conditioner at the recommended dosage. Products do not all have the same concentration; avoid copying the dosage of another brand.
Frequently asked questions
Does a conditioner replace the biological filter?
No. It prepares the water according to its formulation, but does not replace the biological cycle or the nitrite and ammonia tests.
Can the same product be used for shrimp?
Only if the manufacturer indicates compatibility suitable for the invertebrates concerned.
