Well I have been having an issue with low pH so I decided to purchase a bottle of Brightwell Aquatics Kalk +2. What would be the best method of dosing the into my aquarium? I have a 40 gallon Breeder aquarium for the display with no sump. I was going to mix the top off water with the Brightwell Aquatics Kalk +2 and use a drip in an area of high flow since I don't have an Auto Top Off or a Dosing Pump. Any thoughts?
