i use a charcoal and silver dual cartridge filter to treat any water that goes into my vans water tanks or if i am directly using water such as good bore water for immediate use, question..... if i was to filter tank water(Bat/bird poop ect) what would you add to vans tanks to keep it safe.there seems to be a lot of high priced commercial additives which appear to be mostly chlorine .is the pool stuff safe or do you need to pay the big $ for the stuff from the RV shop

If you suspect the tank water has bird/bat/rat poo in it don't use it ... the water would need to be sterilized, tank cleaning agents are for cleaning tanks/lines not for drinking... I have used sterlizing tabs in a past life to make safe some suspect drinking water we had and its not nice at all....

I sometimes just use a normal filter but mostly just straight from tap, as for tank water it really depends the environment its collected from, city can have just as a toxic roof as rural, possibly more so, we lived off tank water for near 30 years and our tanks just had a charcoal filter to filter out any wrigglers, topping tanks with our bore meant the CO2 released killed off the wrigglers and frogs which got flushed out, certainly needed as skeeta larvae could be prolific in times of no rain .
Used to fill the van from my tank at this place but the ash from the bush fires years back and so much pollen here I just use town water and keep the tank for car washing and garden ................... dogs water bucket goes green quicker with tank water than town water ............

I leave my tanks full when parked up, drain every few months and give them a vinegar flush when we get back and a week before a trip .... about 2 litre of vinegar per tank, refill tanks, run the taps furthest away from tanks and leave it for about 2 hours then flush tanks twice and run taps to clear lines, seems to work ..........
Do not leave it in overnight, trust me .... you'll do some flushing then..

Household liquid bleach is good I think its has more hit than vinegar and about 10 or 15ml per tank I seem to recall but I always worry about seals getting a bit iffy if I use it, flush tanks after about an hour ? ............ Either one make sure they don't have any smelly stuff added...

I think the RV shop cleaners are mostly some version of chlorine ....

I also pour vinegar down the drains regularly, keeps them clean as well as the GW tank...

I have found that if tanks are left empty they dry out and the water scale which builds up over time in tanks and lines flakes off and then when filled up again can block things, just like the plumbing in the house lines, though the degree of scale depends on the type of water ........

mostly along the lines of what i already do.any rainwater tank on costal queensland had bat and bird poo in them and you are correct metro tanks also have industrial pollution,acid rain, a lot a people think tank water is pure but if you have ever got into one to clean it out you would gagg, on what is in there
