It is more economics to buy Red Sea AB+ in 5000ml version. However, it is not practical as you have to refrigerate huge jug in the fridge once you opened it as it can’t be left outside for more than a week.
Anyone is buying the 5000ml jug? How do you keep it once you opened it to ensure it stays good for more than a week?
