Tropical Aquacid pH minus is a preparation for lowering the pH level in freshwater aquariums. Acidic water is typical for many biotopes inhabited by fish such as discus, angelfish, South American cichlids, and characins.

Maintaining a low pH level is essential for many species, as it ensures good health, enhances colouration, and promotes successful spawning. Tropical Aquacid pH minus does not contain phosphoric acid, which could cause algae overgrowth.

When applying directly to the aquarium, monitor pH levels using an appropriate test kit. Daily pH changes should not exceed 0.2 pH. The safest approach is to prepare water outside the tank before gradually adding it to the aquarium.

Recommended complementary products: Test 6-in-1, Test pH 4.5-9.5, Test pH 6.0-7.8, Test GH/KH.
