The idea behind an Aquasoil is that it provides the ideal water conditions required by many plants. Therefore Aquasoils are not water neutral either. In the case of JBL ProScape Plant Soil this means that the water's pH value is slightly acidic. It means it resembles what frequently occurs in tropical areas. The GH (total hardness) and KH (carbonate hardness) values also need to be matched. These will be reduced by using ProScape soil.
When you first use JBL's Plant Soil, you need to bear in mind that you should do a water change at least twice a week. You need to keep this up for the first two to three weeks. Why? JBL Plant Soil is full of raw materials and during the first three weeks it "leaches" out large concentrations of ammonia. You need to carry out the water changes to counteract this. The leaching will gradually decrease to a point where the bacteria and plants in the aquarium take over. From then on, you need to carry out water changes less frequently.
