Hi I would like to know how you change water in your aquarium. I take out 8gals. in my 39gal and 6 gal from my 29gal. WhenI add the fresh water to the tank I put in the chorine killer with every bucket. On the bottle it will say 5ml/40gal. or 1 capful for 40 gal. I am only changing 6-8 gals of water. depending on the tank. I have an eyedropper I can put in 1 -2 ml per bucket but it doesn't seem like enough. I had one suggestion to just put in untreated water in the tank and add the chorine killer right to the tank. But I thought the fish will die with just fresh water. How does the expert fish keepers go about this task? Thanks
