Correct, if it's hard for you to measure how much salt to use, get a one gallon jug, premix with AQ salt (remember to add water conditioner too). And pour it into your 2.5 gallon.
Do it until you see signs of improvement, and yeah don't continue this for more than 10 days. If this doesn't work, I wouldn't suggest using AQ salt for awhile.
