Re: [Amel Yacht Owners] Climma A/C saltwater plumbing - Using barnacle buster.
I have done this as a regular part of maintenance every 6 month for the past 5 years. It is perfectly fine to use phosphoric acid or barnacle buster on the AC units. I don’t use BB anymore. I just buy phosphoric acid in the paint department of a hardware store or Sherman Williams for about ¼ of the BB price.
I use a set up just as you describe to re-circulate the acid. Be sure to use a filter in the bucket to catch the junk. I put a mesh balloon over the hose dumping into the bucket so the junk is not re-circulated.
If you use the concentrated BB which is about 17% phosphoric acid, use a solution of 30% acid 70% water in the bucket. There is a lot of water in the pipeline to add to the dilution.
With best regards,

Are we speaking about the AC cooling line?
My plan was you use the Barnacle buster circulating tank and hook it up to the input of the engine room
Manifold, then run a garden hose from the output seacock and back to the circulating bucket.
They suggested to use it for 4-6 hours.
Did you dilute the barnacle buster and if so what ratio?
I will also do so with the engine and genset. I plan on disconnecting the water input to the watermaker while doing this.

I just flush with B.B. and let it sit i the lines over night once a year. So far all lines and manifold are free of any growth or scale.
