Hi all, I'm currently researching and asking questions ready to start my first real planted tank. Some of you will know already ;-). My problem is this. I'm reading so much on water parameters, KH,DH, CO2 to be added, buffers etc etc.. I just can't seem to make light of things. I've read items on the area here and on Tom barrs chats also. My water reads as this using a tetra 6-1 strip: GH- 8*d Kh-15-20*d Ph- 8.0 Now I know following ph/co2 chart will give me a given ppm of co2 to add to optimise growth in plants etc is it as simple as that(not likely) ? Should I buy a liquid testing kit to get exact readings? I will be using pressurised co2 and have been advised to crank the co2 right up whilst plants start off as I won't be adding livestock for few months at least. It's been stated by Tom Barr that a change of 0.2 in ph will massively increase the amount of co2 il have added and that it poses a problem the higher the kh reading is to start with as the amount of co2 will need to be higher thus, gassing the fish to death. The more reading I do folks the more muddled the area comes. Maybe I'm reading too many opinions on the matter? I just need some help understanding It better.. Ask away any questions as I'm sure your probably just as confused as I am after reading my story.. I just can't think of a better way to put things I'm afraid.
