ok just purchased one of those remineralizer that you recommend. Thanks for recommending it! Have you used it before?
Instruction says " to reach a total hardness of about 6 GH and/or a conductance of about 300 +/- 50 uS (Microsiemens). For this purpose, an evenly full measuring spoon (about 2 g) to 10 litres of water is sufficient.Measuring spoon enclosed."
Since im always changing only 25% of the tank water (2.5 gallons of it). im only going to add one full spoon of the remineralizer to the new water?
