Thank you. After I read what I wrote I saw I did not clarify that the ultimate is supposed to he a water conditioner. When I bought the ich x I read all directions and it said not to use ich x with a water conditioner that has sulfur or sulfanilamide (something to this effect). On the web page from the manufacturer it says you can use Ultimate (their brand) water conditioner or two other products they have. You are required to change water for this ich x treatment. I currently use seachem prime as a water conditioner, but it has sulfur (which you can clearly smell from the bottle). The ultimate water conditioner arrived and per the directions it says not to use with malachite green or methalyne blue (sure i spelled those wrong). So yes any advice you can give would be greatly appreciated!!!!!
