Thank you all!
To catch up a little, I do have a DI
unit on the way. I also tend to be a bit of a geek about this stuff and it just feels like I want/need one.
I do plan on using aragonite sand and was reading that this should help the pH, so that makes me feel better.
With fresh water I have always subscribed to the "stable is more important than numbers" method, but this all fells so different and most of what I have read tends to put a little more weight on pH for SW
As long as the water I have made is going to work for curing the rock I'm happy.
