Which is more important? RO or DI?

First.....relax

Best option - not allowed to say

Alternatives - Friend or neighbor with a RO, local store that sells RO (i.e. supermarket) look in the phone book, often water treatment companies sell RO water.

The best long term option is the unmentionable.

Have you tested your water? - TDS? Although not a best practice, there are many that have thriving reef systems using tap or well water. I was amazed to learn the Tropicorium supports their entire operation using many thousands of untreated Detroit city water weekly. If you're not having nutrient/silica/phosphate problems (i.e. algea, cyano, diatoms...) then just keep doing what you're doing and save your nickels for an RO/DI.

You said it!!! then just keep doing what you're doing and save your nickels for an RO/DI. Lol
