how big should ro reservoir?

[Bigair]

in other words how often would you fill your ro reservoir

someone says the big the better, but how would you deal with bacteria problem, dose sth. in the reservoir to restrict them from existing or you think it can be ignored ?

small one should also work combined with auto refill system, but it needs to be reliable


so what is your solution?

Mine is 150 gallons, with 0-4tdc there should be no bacteria in it. That's what ro is for to get rid of everything in water

That is likely due to air contemplating water. 0tdc water that is sealed should have no bacteria of any kind, also 0 tds water is like a sponge for polutens that are in the air.
