I can dose a planted tank without using a pH/KH test method also, so can Amano.

As long as I have some way to see the rate of dosing, say a bubble rate, I can get a rough target and then tweak without ever using a kit.

Sort of EI for CO2.

The important steps are:

1. Add CO2 only when you need it
2. Add it slowly over the course of several days between each bubble rate increase,watch fish etc.
3. BACK OFF when fish are at the surface in the AM.
4. Make sure there is moderate surface movement.
5. Make sure there is high plant biomass

Tom, you brought up the EI method for CO2 dosing at APC which got me thinking. Isn't it a tad too late if the critters were at the surface gasping for air when we should have notice heavy breathing of fish before that?

Re: EI for CO2

Yep, but it's easy enough to back off, I've never lost a fish, but I've had them gasping at the surface, but not for long and only when I have less surface turbulance.

You just need to watch the fish for the first day, and then watch the weeds for that week.

Then add a tad more the following week till things look good, you do not need to have the fish gasping to get good growth, no BBA etc, quite a bit before that, but folks do need some surface movement and not add it during the day, I'm telling folks, you can add more gas this way with less chance of killing the fish.

Are you referring to not adding the surface movement during the day? or something else?
