Already in the early stage of a disease arising (fish rub, swim restless and take refuge in the darkest areas of the aquarium) you should proceed immediately to treatment with Neosal. To counter the strong proliferation of flagellates, salinity should be lowered to 1,018 and lighting greatly reduced. To protect the mucous membranes of the fish, the pH should not exceed 8.2; in the case of new purchases and medical treatments, therefore do not add to your aquarium water limestone to increase the hardness of the water. To increase safely the calcium content in the water of your aquarium, we recommend to ALPHA MARIN, which does not cause an increase in the pH value, or FORMEL PREIS KORALL as PREIS MINERAL SALT.
