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

Usually, we see at our tank and think, "Hey, its a 50-gallon tank, correspondingly a 10% modify is 5 gallons." Simple, right? Wrong.
