How much rinsing after citric acid?

[aaron186]

I have a reefer 350 that sat dry for a year. I just cleaned it today with 5% citric acid from BRS. I dumped 5 gals of it into the bottom and used that to clean it and then removed the water with a shop vac. How much rinsing is necessary before I start the tank back up?

I would rinse until you can not longer detect any citric acid residue and then do about 2-3 more rinses.

I would just hose it out, wipe it down and call it good.
