its says one tablet is for 10 gallon tank. I have a 3 gallon so I split it in half. I added the first half jan 7. jan 10 I took out 20% of water (which I converted into 10 cups) then added the other half do you no when I should completely clean the tank out? or should I add a 2nd tablet? it says on the package "A second dose may be add to water in four days. change 25% of the water before adding second dose"
what do I do?
