My design should be up once I get my stupid line running at home. Phone company wants 10 days. I might just go cable and say forget the phone line altogether.

Subscribers will get the external version diagram and pics in a few weeks.

Sure, I see no reason why not.
I don't use CO2 at night personally, I really don't suggest others to do that either. Amano is in the same camp on this.
We both have our reasons.
Mine is mainly so I can dose high levekls only when it's needed. This allows me to add higher levels than anyone using a 24/7 method of dosing with much less risk and fish issues.
Since most of the 12-14 hour dark peroid has no CO2 additions, the O2 is still there(and quite high most of the time) the CO2 levels drop off and are a non issue most of the 24 hour cycle.
I can handle being hot for 6 hours a day but I'd hate being hot 24/7.
The higher CO2 also reduces O2 use by other organisms. So adding it only when you need it, allowijng the O2 to stay at a high level till it's all used up seems the best method.
