Hello; I've been thinking about your comments and still do not understand why it is necessary to use prime or any other chemical conditioner in this instance. The issue is how to clean out a tank that had a bit of bleach in it to kill insects. The OP is in the process of cleaning the tank prior to a setup. Several other forum members have posted in other threads about using bleach to clean/disinfect their tanks and equipment and have stated that they rinse it well. I do not recall them saying chemical treatment being involved.
At the point when the tank is setup and tap water or questionable well water is being added with the intent of leaving the water in the tank and adding fish, there may be a need for some chemical treatment. This will only be needed if the water source has chloramines or some other
chemical in the water.
Should the OP be in a community where the water company only uses chlorine, such as mine, then the water only needs to be aged a while to be safe for aquarium use. If the Op has good well water there is also no need for such chemicals.
I have been fortunate to live in areas where chlorine is the only stuff used to treat the water supply and have been aging water in containers for over thirty years. This method works.
