Can anyone suggest any good reads on....... CO2, Ferts, and Water Parameters? I am looking to try and compile somewhat of a quick reference beginners guide from many sources to help me sort out all of this. It seems to me the hobby is a lot more complex now than it was when I was a kid. I thought if I could compile a quick guide to these topics it would be very helpful not only to me but many others that are new to the hobby or getting back into it after years away like myself. I am not trying to re invent the wheel so if there is already a complete read on these topics, please let me know where to find it. I have looked at some but wanted suggestions from you.
