Faz o que promete.

Hat nicht funktioniert, Wasser blieb hart. Darüber hinaus verloren die Fische ihren Appetit. Hab 3 x Wasserwechsel gebraucht, damit sich die Fische wieder erholen.

Resolveu meu problema para regular o ph do aquario. Usei junto com o neutral regulator.

The best products for ponds. Forget about any other type of products you only need PrimeC alkaline, acid and ph regulator of this brand. Nothing else works as efficiently as these products!

There are two stages to using this product: initial pH lowering and pH maintenance.Initial pH lowering is a major pain, but you only need to do it once. Water pH levels are held in place by chemical buffers which gives the pH stability over time. The initial lowering is tough because you have to "beat back" the alkaline buffers in the water. In fact, because of the buffering effect you could have no observable change for a long time and suddenly the pH starts moving fast. It's just like cycling the tank for the first time, when you wonder if ammonia levels will EVER drop.pH maintenance is much easier. If you use a bucket to do your water changes, you can fill it up with water as normal and see what combination of acid and neutral regulators give you the pH you want. That is what you then use when you fill the bucket for water changes!Another nice feature of this acid regulator is that it softens the water. Note though that if you use aeration in your tank, the airstone will work kind of like a protein skimmer. When the air bubbles pop at the surface of the water, a little bit of sediment gets thrown out. Over time, that sediment can build up, making the top of your aquarium crusty. It's easy to clean off, but can be a head-scratcher at first!
