Sanitising Water system

These Steramine Quaternary sanitizing tablets looks like a better sanitizer than using bleach and is inexpensive. It's use extensively in the restaurant industry.

We do carry a few bottles plus some cans of sparkling flavored (unsweetened) water. For coffee and tea, the water comes from the tank. We also fill reusable stainless steel bottles for drinking. For the most part, we limit showers and have had access to places to both dump the gray and black tanks as needed and to refill the fresh tank as needed. We learned to take very quick, low water use showers on our first trip and to use campground showers if we are at a place without hook-ups (such as Vermont state parks). I carried a water container (Hydroller) when we were dry camping in freezing weather. It is still water carried in a container that is of similar material to the fresh water tank so I treat it the same way.

I have a 178 that was winterized by an RV dealer last October and then stored in a covered barn. Went to clean out the tank and fill with fresh water only to find what I assume is algae in the tank. Green leafy things came out when I first flushed it. Any tips on how to get rid of it? I thought about using bleach in the tank with water but am open to suggestions, advice, ideas. Thanks.

Sure. I use my garden hose to fill mine. If I was drinking out of it (which I'm not) I guess I might pour some diluted bleach through the hose if its been sitting around awhile first and I was really worried about it. 

Yeah just flush water thru that garden hose for a minute before you insert it into the fill port.
