I'm doing water changes on 4 different size tanks. 5, 10, 15 and 55 gallons. I'm using the API tap water conditioner to take care of the chloramine that is in my tap water. I'm having difficulty determining just how much conditioner to add, especially the smaller tanks. Directions say to ad 1 ml to 5 gallons of tap, but on the 5 gallon, I only change 1 gallon at a time. It's difficult to determine by using the cap measuring ml lines to determine to proper amount. I'm trying to break the measurement down to the amount needed for one gallon. The pet shop owner told me to use 1 drop per gallon. I asked him one drop from what, and he said any type pf dropper. Even I know there are several different sizes of droppers. Can you overdose the fish on dechlorinators? All the tanks except the 55 have fancy guppies in them.
Thank you in advance.
