Improve water quality
To improve the water quality of your pond, start by testing it, then correct in the right order: hardness, bacteria, organic matter. Sera tests, KH and GH minerals, nitrifying bacteria and cleaners are all gathered here.
How to choose the right product for your water?
- Test first: pH, KH, GH and nitrite, with a drop test or test strips.
- Correct hardness: with KH below 7, add minerals first (MinerAll In One up to 100 m³, Nautex beyond).
- Consider the surroundings: trees, number of fish and aquatic plants help you interpret the results.
- Support the filtration: NitriBoost at start-up, then Bacto Maintenance.
Read: how to carry out a water test and how to raise KH. See also pond water testing and hardness products.
* Excludes bulky, heavy or fragile products: they are delivered by a specialist carrier and delivery costs are calculated automatically in the cart.
