I used to lug water back and forth and many told me to get an RO
system and I thought it was not worth it.
I caved in and bought a 5 stage RO
system on e-bay for $100 including shipping.
Do the math....even if you only do 1 mth water changes and top ups, the system will pay for itself after 1 year.
I won't even talk about the water lugging factor
