Thank you so much for the advice, I am a little confused and was wondering if you mind clarifying for me...
Just so I understand, I should add 3 tsp. of salt per gallon total over a period of 36 hours (1 tsp every 12 hours). then change the 100% water 12 hours after that with new water, pre-salted to the higher dosage?
Then continue to change 100% of the water with the higher dosage every day, for 14 days ever day.
Will this amount of salt be okay for the fish for 14 days?
Will changing 100% of the water be too much stress for Guppy?
Do I need to remove plants and gravel from the tank that is already there or are you referring to new gravel if I bring it in?
If I treat the whole tank doesn't it take care of all the ich living in the tank?
