Youve already drained the tank. Your corals are screaming at you bearing in mind their slimy, retracted polyps. Your prized clownfish is looking at you with youve bungled him. This is the moment every reefer dreads. Its the "saltwater gap." If youve ever wondered how accomplish I determine the amount of saltwater water to make, you arent just asking for a measurement. You are asking for a survival strategy.

Usually, we see at our tank and think, "Hey, its a 50-gallon tank, fittingly a 10% regulate is 5 gallons." Simple, right? Wrong. Its never that simple. in the midst of the rocks, the sand, the plumbing, and that enormous protein skimmer you spent too much child support on, your "50-gallon" tank might abandoned preserve 38 gallons of actual liquid. This is where the aquarium water correct calculation gets messy.
