Here is my plan:
-I'm going to fill my sanitized 10 gallon tank with 8 gallons of water.
-I called a local pharmacy (small town

) about measuring out mg of powder, and he offered to measure it out for me on his scale. So I'm going to have him measure out 240 mg to fill the tank initially. And if possible, I'll see if he can measure out three more 30 mg doses so that I'll at least have three one gallon water changes when needed.
-Typically, I change out about a quart a day in my QT just siphoning out waste and leftover food. But because any replacement water has to have Ick-shield in it, and small amounts are hard to measure, I'll just keep track of how much water I use until I reach one gallon. Then I'll mix up a one-gallon batch with the smaller dose the pharmacist measures out for me, and add it back to the tank for a refresher.
-Of course I'll top off with unmedicated RODI as usual. In this case, I'll have to move the tape marker each time I remove water so that I'll know how much to top off for evaporation.
-I'll use Prime as needed if/when ammonia rises.
-I'll do all this for 21 days according to the medication instructions. Then I'll move them to a second sanitized tank for 2 weeks of observation.
-I'll have an antibiotic on hand in case it's needed. (I haven't gotten this far yet, but I'll be headed to my lfs this weekend to get some frozen food on sale.)
So if all goes well, will they be ready for the display after the two weeks of observation???
