Storing water

[maestro]

I use a nitrate filter as my tap levels are 50-70ppm sometimes

Is it ok to store the filtered water up to a week without aereation? its a pain to keep filtering the water everyday for water changes

How big is your tank? Is your tank sealed? I don't know how much bacteria would grow in a tank of nonchlorined water over a weeks time.

I will use a 25 litre drum with a screw lid (this is for my ram tank) Its the ones that people use to buy RO from shops with

It is chlorinated as its just filtered tap water,the filter only gets rid of nitrate and phosphate.

I want to filter of 25 litres at the wkend and store it im my room for use during the week

I dont want to use an airpump as 1) i dont have a spare and 2) there too noisy for my room, even the quiet ones keep me awake.

Do you think it will be ok?
