what do you mean you "paid for a guide"? on here? the only thing I have ever paid for on this site was a donation. That is the only thing I can think of.
Regardless, Im not sure why you would want to buy a guide to a build a planted tank. There is a plethora of information on the web about doing this. Heck, you can go to any LFS and they will explain stuff to you
