DIY RO Unit (inexpensive option?)

[lastlight]

Further reading suggest the starter filter makes a few gallons and the replacement about 10 gallons. If you plan to be in this hobby long-term an actual ro/di unit is a great investment. If that requires saving up I'd still use ro water as a temporary solution as these things have been discontinued.

Thanks for your opinions guys, I am not sure if I will try this or not. I know that you can get this system at Walmart (so it must not be discontinued). I have thought about a used RO system....

Mostly I would like to know where I can buy RO water for $1 dollar per 5 gallons......cause then I will just buy it with only one water change every 2 weeks to a month that will be a cheap option!! (sphelps??)

Thanks to globaldesigns for the info about Calgary water!

Obviously the most important thing for my small system is not introducing Phosphates via my water changes...this could be detrimental to my system....so I definitely need to use good water!

I think a product still being available and being announced as discontinued are two different things was just mentioning that as I read it in the original thread you posted =)
