Constant CO2 for a fish tank has a price the question is in what way you pay it!! , it will be wrong to state that constant PPM cannot be achieved by DIY CO2. It is possible to achieve this by doing combination of bottles and also keeping constant eye on CO2 production ( the price in this case is time one need to spend and effort one need to take) for X this will be cheaper and for Y this may be costly considering his work etc. So it is for the individual to choose between these two. For me spending time for replacing bottles and keeping constant watch became expensive than the amount that I need to spend on a pressurized setup. So I decided to replace my DIY to pressurized. There are several earlier posts where people explained use of multiple bottles to achieve the required CO2 levels depending on the size of the tank....

It is not safe, the bottles used in diy co2 are not built to withstand pressure.
The production of Co2 cannot be controlled.
There is a danger of Bottle exploding or tubes popping out.
It is better to use diy systems without stop valves.
However a simple check value can be used to stop back flow of aquarium water in the bottle when gas production stops, but even this should be cleaned on a monthly basis.
