cleaning water tanks

oh your actual question, water conditioners. personaly i doint like them mainly becouse you doint know whats in the water to start with and what you actualy need to treat it so adding stuff willy nilly i doint beleve in.

good clean dry tanks, town supply water, no light = 1 week. after that i would and do boil

We remove the filters from the bowls, vacuum seal them in bags and stick them in the fridge between uses. Also replace every 12 months regardless of how often they are used.

Darkside is correct about carbon filters

Recent studies in Adelaide show no difference in infection rates between those using rainwater and those using town water. Most rural residents use rainwater without filtering and without ill effects. These facts suggest that the risk is overrated.

The amount of particulate material needed to nucleate rain drops is so small as to be almost unmeasurable. Much more comes off the roof than falls in the rain - hence the devices that discard the first few litres, but as a general rule, while not as sterile as town water, rainwater presents little risk unless there is some form of overt contamination such as birds nesting on the roof.

I'm glad Ron didn't see that one:TIC:

All corrected now;)

Been raining all afternoon, if this is climate change ,bring it on.
Water tanks nearly full . Two 10,000 gal tanks, never had filters untill the possum population grew and use the roof as a racetrack. Cockatoos roost on it and frogs live in the downpipes. With all that poo, I decided to put a 10 " carbon filter in the supply to the kitchen sink and icemaker water dispenser fridge. Not the whole house. Filters to 1 micron and I change it when the output from the sink tap drops off. Maybe 4 to 6 months.

No problems so far.

To be honest, most people are not affected by bacteria in the rainwater (except in extreme contamination situations), but to filter it out effectively, you'll need at least 0.4 micron.

Davey Water Products have an item called Acquasafe (I think). Essentially it's an oxidising agent that you add to the tank (similar to hydrogen peroxide)than burns (kills) the bacteria, and converts to water in the process. Also contains a silver colloid in trace amounts too. Highly recommended but the water companies, and used by B&B's, and food production facilities that use rainwater.

Another effective method is UV. Not cheap either, and not exactly portable.

Surely a T piece in the line with a bung in it is easier than removing the tank to put a drain in????

I'd be sure your tinfoil hat has a brim, so as no rainwater gets on your skin:D

If it smells and tastes fine, its fine;)
