High-quality complete CO2 set with night shutdown

This is a very high-quality CO2 set.
The set consists of: a 2.1 L CO2 bottle (which is half full and has a valid pressure test for another 9 years), a professional, very precise regulator from the brand Strideways (this brand definitely needs no introduction), a metal/glass bubble counter, the necessary high-pressure tubing, and a stainless steel diffuser. Everything is fully functional.
With this set, your plants in the aquarium will grow literally before your eyes.

The current price for everything is approximately 3,800 CZK.
I am selling it at a very advantageous price.
I am happy to answer any questions, and I can also help/advice with the setup.
