Sweet water tanks: descale and disinfecting, what first?

[CaptainRivet]

Hi all,

My both water tanks (350l each) are very scaledand need to be descaled with Yacticon descaler.
Assume also some pipes are scaled too, a lot are newish but not all.
also the cat was 14 month on the hard for a big repair so the water tank and pipes need to be desinected and cleaned too, will use Yachticon Tank supercleaner.
But what do do first?
I would descale first, correct?

There does not seems to be a question in there. You said what you were going to do.


It seems to be a citric acid cleaner (not in English, and this is an English-based forum). That will also disinfect the tanks.

The clean a tank is citric based mainly for decalcifying and yes it also does desinfection mainly the tank itself while the super tank cleaner is much stronger in desinection and works magic on all the pipes plus tank and mainly clean all the other sluge like eg algee etc but not working for decalcifying.
I before used each individually on my old ketch but never in series....
Question is just which way is best, first clean a tank and decalcify or super tank cleaner clean out the other sludge and then decalcify...
