   Hi, you need to proof read your articles. There are contradictions around co2 and ph levels. Also the grammar could flow a lot better with some refinement.
   
   Still, very informative, thank you.

   Hi Ryan just read your article and found it very easy to understand and informative, no doubt like me it as helped lots of people understand KH/GH values.
   Thanks for taking the time to compile this article
   Thanks Richie

   Hey! Just wanted to let you know your first paragraph doesn’t make sense. There’s a whole lot of increases in those sentences :). Otherwise good

   Hello Ryan,
   Ryan I found that since I dose CO2...I actually have the timer come on and off through out the night to keep my pH steady...since I am dosing at levels that result in CO2 in the water at higher levels than what would be in equilibrium with the air...the CO2 degasses during the evening and my pH would rise...
   I also run my tanks with pretty much zero KH (amazon biotope tanks) and the shrimp are breeding quite frequently....
   Your article is one of the better ones I have read regarding KH and pH. One edit, 3rd paragraph near the end, you state the plants stop utilizing CO2 and this makes your pH increase....which you correctly restate later that it should make your pH decrease.
   Regards
