Osmo Fit

Ideal for hardening soft mains water or remineralising ultrapure water. With a Ca : Mg ration of 4 : 1 and a KH : GH ratio of 1 : 2.2. Osmo Fit contains all trace elements and is free of sodium chloride, phosphate and nitrate. 400 g is sufficient for 4,000 litres with an increase by 1 °KH and 2.2 °GH.

Dosing: To increase 100 l of water by 1 °dKH you need ten grams (g) of Osmo Fit or to increase 100 l of water by 1 °dGH you need 4.5 g Osmo Fit.

Aquarists who keep demanding animals often use reverse osmosis water to adjust the water values precisely to the needs of the fish in their care. But careful: The reverse osmosis water must not be used pure because it no longer contains any minerals. With the hardening salt Osmo Fit you add to the reverse osmosis water (also known as de-ionised water) all necessary minerals in a precisely defined ratio. Osmo Fit is free of sodium chloride and phosphates or "fillers" and contains all trace elements that occur in natural waters with the exception of marine water. Osmo Fit increases the hardness at a KH / GH ratio of 1: 2.2.
Our recommendation: If you wish to adjust a different KH : GH ratio, you can combine Osmo Fit with the products KH / pH Fit plus or GH Fit.
