Hi there,

I've been kind of lurking here for a couple of weeks, but I now have a
question.

With some help from the greatest LFS that I've ever known, I put
together a DIY CO2 unit today. It's the most basic one, a 2 litre pop
bottle, a checkvalve, some airline tubing, a rubber stopper, and an
airstone.

I've had the solution ready for about 1.5 hours, and hooked up to the
tank for about 1.25 hours. I'm already seeing fizzing through the
wooden airstone, so it seems to be working REALLY well!

My only remaining question is - what should I be looking for in
changes for water chemistry?

My current water is:

pH 7.8
No2 0.1
No3 0.0
kH 100
GH 200


Thanks!
