Treating fish for Ich (hybrid aquaponic system)

In this video I show you how I treated my fish for Ich. Unfortunately my fish got Ich after introducing new fish into my aquaponics system. What I will do next time and every other time to avoid this is to quarantine any new fish I get for 1 to 2 weeks before putting them in to my system.
I used Epsom salt to treat them, 1 teaspoon to every gallon of water. And I did this for 3 weeks doing water changes and adding new salt each time.

Here is a safe aquaponic ich treatment if you don't want to use Epsom salt:
