I'm thinking of dripping kalkwasser into my 20g mixed reef. I've been having trouble keeping my ph up as it sits pretty low now around 7.7-7.8.
What's the best way? I was thinking of just dripping it when needed during lights out when natural evap occurs. Now, I heard that the solution loses potency as it ages. Is it really going to change all that much in one week? I go through a gallon a week of top off water.
Also, since it's a small tank, I'm assuming it'll maintain alkalinity and magnesium through water changes.
