I have been utilizing Tropic Marine Pro for over 6 months. I have a 160 gallon storage tank that is spotless after switching to this salt which makes me hesitant to ever make any changes again. My only issue is I would really like to get my alk to stay consistent at 8.5 - 9 dkh in my DT. When performing large water changes, I manually dose BRS soda ash to my sump where the new water is added in order to accommodate the low alk in Tropic Marine Pro. This process is very time consuming and never consistent. I was wondering if there are any reasons I can not pre "dose" my storage containers to get the desired dkh so at the time of a water change, I can match my system without all the hassle? Typically, the storage containers are replenished around 4-6 weeks, depending on the amount of water changes and extra tanks needed. Any advice on this would be greatly appreciated.
