White build up in water tank

Hey friends put an endoscope into my water tanks and discovered some large white build up. Heard that it may be the chlorine reacting with the aluminium over time? Any solutions beside replacing tanks?
Thanks!!

Re: White build up in water tank

Most likely from putting chlorinated city water in the tanks. Easiest way to slow the build up is to only put non-chlorinated water in the tanks by passing the water thru a carbon filter first. The slower the flow thru the filter, the better it will remove the chlorine.

Helpful resource is also Peggie's book, containing "all and everything related to marine water systems" (Don't let the title fool you):
