Sorry but I don't agree with this sentence!
Yes, a Co2 controller give you a more stable PH/Co2,
but the circulation of water is essential for a good co2 distribution,
you can have dead/hot spots with or without the controller!
In my opinion, the controller, if correctly calibrated/used, will give you less fluctuation of PH/Co2
and the co2 bottle will last longer, but it's not essential!
The drop checker is a visual aid..... it will give you a visual alert if the controller "go mad"!
