What's the exact amount of salt in tablespoons shouldI put in a 60 galtank?DonH said:There are many "Rule of Thumb" guidelines for how much salt to add. Either, 1 tablespoon per 5 gallons, 1 tbsp/10 gallons, etc... If this has worked for you in the past, fine. I have always dosed my tanks at 0.3% (3 tsp/gallon) when needed, which is considerably higher than many suggest. Only exception to this rule is for nitrite poisoning where a teaspoon of salt will treat over 300 gallons of water. Many believe that the constant use of salt in low dosages is the reason why we are having problems with salt resistant parasites. And as a result, some parasitic infestations need to double the dosage to 0.6% to see any significant improvement.
My recommended dosage, even for ich, is 0.3% (which is a TOTAL of 2.5 lbs/100 gallons or 3 tsp/US gallon). The amount of salt added should be done in 3 equal increments over 3 days and left in the system for 2 weeks (that's 1 tsp per gallon per day for 3 days), in which time, the salt should be taken out through water changes. ALWAYS pre-dissolve the salt before introducing it to your tank! Measure out the desired amount of salt, add aquarium water to a bucket or cup (I use a 44 oz plastic "Big Gulp" cup) and stir like crazy until the salt dissolves. Slowly pour the salt solution into the tank and make sure you are not pouring it on top of your fish. I prefer to pour the solution in the path of a powerhead to help distribute it throughout the tank. A "blast" of concentrated salt solution may cause severe burns to your fish. Therefore, NEVER add salt directly to your tank.
