CaribSea AragaMilk (473ml)
This unique product provides two types of buffer in one: bicarbonate for immediate response, plus carbonate from aragonite. This second form makes a safer, time-release buffer, over 2-3 days, for long term security without the wild pH swings that can stress your tank inhabitants. You’ll notice it will stop downward pH swings so common in large fish only marine and Cichlid set ups. Great for livebearer aquariums.
