RO...RO/DI choices

[Bartman]

Howdy Canreefers,

I have enough small fresh and salt tanks in the house it's time I looked at an RO or RO/DI solution. Especially as our Langley water has taken to creeping up over 7.6pH within hours of going in a tank at 6.8pH and buying RO for the reef is getting $$$.

What have you folks found as an efficient, inexpensive solution? Is RO good enough or should I add DI? I probably only use 20G a week now but I will be adding a larger reef tank (aren't we all ) in the not too distant future. I appreciate any feedback.
