High pH and low KH.
There is a not-so-accurate way to determine CO2 levels based on pH and KH levels.
Here’s one page that explains it and has a chart. This is based on accurate test results of pH and KH so it’s important to be consistent when testing at a certain time of day and keep track of your own numbers. http://www.thekrib.com/Plants/CO2/kh-ph-co2-chart.html
Chuck’s Plant Pages also has a page about this and has a calculator built into the page rather than a chart. http://www.csd.net/~cgadd/aqua/art_plant_co2chart.htm
Here’s a page on how much Baking Soda to add per gallon to raise the KH a certain level including a calculator. http://dataguru.org/misc/aquarium/calKH.asp

PS - As far as Bill’s assertion… “There are still idiots out there who preach that water changes are the answer because “DILUTION IS THE SOLUTION TO POLLUTION!” Not true if your incoming “water” is a problem and you are not diluting, but adding to the problem.”…
I guess I’m one of them idiots. LOL I’m sorry but even if your source water isn’t perfect, you still have to rely on “Dilution is the solution to pollution”. It’s just a little rhyme supporting PWC’s (partial water changes). You may have to add dechlorinator and possibly other water treatments to make your source water better but you still MUST do PWC’s so unless you are going to drill your own well and have it regularly monitored, then most people are forced with using their own tap water for their own “Dilution is the solution to pollution” (aka partial water changes).
PPS - Bill… they ship the styrofoam safely packed in corrugated fiberboard… aka a box. LOL
