I would take well water over a town or city water anytime to drink, but municipal water has the advantage when it is going to sit for any extended period of time. That chlorination should keep things from growing in a camper fresh water tank.

One of the last things we do, when packing up to go home after a camping trip, is open the pit cock drain valve on the water tank. We leave it open to drain all the way home. The water sloshes around and pretty much completely drains out. If you are traveling a ways to get home, when you make your first "pit stop" it should be finished draining. You can close the valve at that time and be done with it.

Well water is notorious for that slimy stuff after sitting in a holding tank for extended length of time. As "mtnguy" stated, the chlorine in "city" water helps to prevent it.

Please go easy on the bleach. That stuff is surprisingly strong and a little goes a really looong way.

as many pool owners know ... green algie is ok and workable, but black is definately a problem situation. House bleach is not as concentrated as pool shock, and this definately sounds like you will have to shock your tank. Add to this some liquid algicide, mix up the concoction before you pour it in, drive around a bit like everyone says, but then continue to leave it in your tank for a few good hours, allowing the chemicals to work, and to kill off the bacteria. Its most likely that the water that has gone bad in your tank was just a small amount of residual water left there over the winter, or from the previous owner. Once this is all done ... rinse, rinse rinse, by filling and draining your tank numberous times .. making sure not to run the chemicals through the rest of the plumbing in your trailer. This should solve your problem.
Before you do all this tho ... make sure you are dealing with an algie problem .. not some dirt that just got into the tank from some campsite well that was overtaxed ... and was pushing dirt and guck out through the fresh water fillup hose.

hope this helps .. d-mo

Thanks everyone for the recommendations.I put about 3 oz of bleach in with some water in the tank yesterday.I filled the tank and let it sit for a few hours.Then drained it somewhat and added more water as I was afraid I might had the bleach mix too strong.I let it sit overnight and went out and checked it again.It looks like the bottom of the tank is almost free of the black material.I would guess there are only two or three spots showing on the bottom of the tank now and none arent any bigger than a quarter.I drained the tank empty and those spots are still there.I also filled the tank again and ran fresh water from the hose through it.I havent hooked the camper up and driven it around yet as I havent had time to do that.I plan on closing the valve back and adding more bleach and water and letting it sit overnight again.I will more than likely drive it around tomorrow some just to make sure all tank parts get covered and to loosen the remaining stuff up.I think my tank is about 26 gallon so I plan on adding about 2 ozs. of bleach and filling the tank about 3/4 full for an overnight sit.Then more than likely driving it around tomorrow some time.
Once I do this would it be best for me to just drain the tank completely and let it sit empty until I plann on using it again?

Drain the bleach mix. Then fill again with fresh water and drain again. If I don't plan to use the trailer for a couple of weeks, I leave the fresh water tank empty.

Household ultra bleach is 6% calcium hypochlorite. Liquid pool shock will be 10 or 12%. If u choose liquid pool shock make sure that it doesn't have any other additives such as copper sulfate or other algecides. I personally think algecide is unnecessary for sanitizing and killing any algae.

You won't hurt your plastic tank even with full strength 12% calhypo. The rubber seals, washers etc in your plumbing (and hot water heater) however are another story. If any of the 'shocked' water gets pumped through your system be sure to flush with straight water thoroughly.

For a typical swimming pool, 3 quarts of 6% bleach will supply about 5 parts per million of free chlorine in 18000 gallons of water. Enough to maintain clean water for 24 hours. I used to use 6% bleach for my pool until Katrina shot bleach prices up. I shock (to kill algae) with 15-20 parts per million of chlorine. What I'm trying to say is that 1/2 cup, 1 cup or even more will kill any algae and nasties with a a short soak. Some agitation of the tank will loose thing up to drain away.

Now I'm even more eager to get my A126 out and give it a good going over. The tank is something else to check out.
