[Sentoa] Fresh Water Tank Treatment

[bshap72181 at aol.com]

Elliot,

If your tanks are aluminum, you really do not want to add any extra chlorine (bleach) to the them. On a previous boat, an Island Packet, the prior owner added Bleach regularly to the tank. After some time, the tanks developed pinholes at the seams and could not be repaired, They needed to be replaced. Not something I wish on anyone. Very expensive and very disruptive to the boat. When we took the tanks out, there was a thick white flakey layer of that I beleive was Aluminum Chloride.

What is supposed to be safe is the use of  Hydrogen Peroxide. I would suggest checking with a druggist for a formula for disinfecting.

Also, the following is for another peroxide type product that came from the Island Packet List.

Strange name, but it is for a product called Purogene that is used as a disinfectant.

I use a prefilter on all the water that goes into our tanks. It is nothing more than a small water filter made up with garden hose ends on it. One end attaches to the water source hose (marina) the other end goes into the tank. I flush the filter and marina hose for a couple minutes before allowing water into the tank.

Good luck...

I have discovered that our 50 gallon fresh water tank had developed some
ind of thin membrane growth which breaks up and floats out of the deck
illing when we refill the tank.  It is clogging our fresh water pump filter
ith a thin brownish film.  Whatever it is, I would like to clear it up and
hought about adding Clorox to the tank and letting it sit for a day or two
efore flushing.  Has anyone experienced a similar problem and how was it
reated?  Thanks in advance for any advise. Elliot Kocen, Canvasback, NT
