I am looking for information on how fast I should re-add co2 to my tank? 
My tank went from 6.7-7.6PH before I had a chance to buy a replacement Co2 bottle. 

Last time this happened I dropped 0.2PH each day to get back down. Is there any information or a standard to go by for the "correct rate"? 

Cheers 
Cameron.

In general, that sort of drop (less than 1 ph point) is not much for most fish - particularly if they have already been in an aquarium with CO2 injection before. But to be safe, go down to neutral first for a day, then go further the following day.
The danger is not so much the actual pH, but the amount of dissolved CO2 that causes issues with some fish.
