Foam coming out of fresh water vents

[nautibake]

I always add about 3/4 cup of household bleach when we fill fresh water tanks. 300 gallons is the water capacity. Sometimes white foam bubbles out of the vents as the approach full. Anything to be concerned with? We do drink the stuff daily after 2 levels of charcoal filters.

I noticed this also with the "new" no splash bleach and no we do not drink it .....Pat

We have now and have had on previous boats the charcoal filters. In addition, i have a SeaGull water filter (that removes bacteria and viruses) through its own separate tap in the galley for drinking water, cooking and another line to the ice maker.

Short of reverse osmosis, the water coming from the SeaGull is about as clean as you can get.

Use Liquid Pool shock, has no perfumes and is true chlorine bleach, not hydrogen peroxide.

Chlorine is not good. Pool chlorine is just higher a concentration. No splash has been thickened with an additive to increase viscosity. Usually a soap.

Bleach is caustic, causes eye irritation, gastric burns, is corrosive to metals in high concentration or long exposure. Its not necessary unless you have a contamination in your water tank.

Thank you good to know, i will not use it anymore.

Thanks everyone, really appreciate the inputs! Sounds like I am okay at these concentrations and maybe just dilute in advance of pouring in to potentially lessen the foaming. We were in fact using the low-splash variety and that definitely sounds like a no no. we live aboard and go through 200 gallons / week on average. Unless of course my boys and their girlfriends are on board, in which case it is 200 gallons/day!!

I would probably feel better if I just open up one or both of the tanks at the flange and have a look inside. Of course the extra measure of protection with preferred vodka (safety first!) is a must... :-)

Found this online:

Disinfect water using household bleach, if you can’t boil water. Only use regular, unscented chlorine bleach products that are suitable for disinfection and sanitization as indicated on the label. The label may say that the active ingredient contains 6 or 8.25% of sodium hypochlorite. Do not use scented, color safe, or bleaches with added cleaners.If water is cloudy, let it settle and filter it through a clean cloth, paper towel, or coffee filter.
Locate a clean dropper from your medicine cabinet or emergency supply kit.
Locate a fresh liquid chlorine bleach or liquid chlorine bleach that is stored at room temperatures for less than one year.
Use the table below as a guide to decide the amount of bleach you should add to the water, for example, 8 drops of 6% bleach, or 6 drops of 8.25% bleach, to each gallon of water. Double the amount of bleach if the water is cloudy, colored, or very cold.Glass containers with droppers
Stir and let stand for 30 minutes. The water should have a slight chlorine odor. If it doesn’t, repeat the dosage and let stand for another 15 minutes before use.
If the chlorine taste is too strong, pour the water from one clean container to another and let it stand for a few hours before use.

Volume of Water Amount of 6% Bleach to Add* Amount of 8.25% Bleach to Add*
1 quart/liter 2 drops 2 drops
1 gallon 8 drops 6 drops
2 gallons 16 drops (1/4 tsp) 12 drops (1/8 teaspoon)
4 gallons 1/3 teaspoon 1/4 teaspoon
8 gallons 2/3 teaspoon 1/2 teaspoon

*Bleach may contain 6 or 8.25% sodium hypochlorite.

What about the ice?

Ingesting chlorine bleach in any form is not a good idea.
