Sorry that it took so long for a new video to come. I have neglected my aquariums a lot, just like my Instagram. But today I refilled my Co2 system from @co2art and now it can really start again.

I also hung the hooks on the ceiling and hung the hyperbar led lamp by @skylightaquarium.
I would also like to thank my other partners:
@baqubrindisi for hardscape material and more.
@iac_crew_ for all the advice I've received.
Soon the tank will be filled and I will proceed to planting.

I always like to try different equipment setups and learn from the different combinations , but I always re-use my @co2art system!

Pro tip: for each scape I have dedicated @co2art system that I set and never touch - it always hits the golden point - so I don’t have to set it up again and again :) what works I don’t change 😂😂

The new generation of our most popular dual-stage CO2 regulator, redesigned with a new pressure-stabilising construction: much larger internal springs give safety and precision at the highest level.
The dual-stage design keeps the output pressure steady as the pressure in the cylinder drops and prevents an end-of-cylinder dump, so your livestock stays safe and the CO2 level constant.
Features
- Safe 12 V DC integrated solenoid valve
- Power adapter with universal voltage, 100–240 V
- Adjustable working pressure up to about 3 bar (40 psi) — right for tropical and marine aquariums alike
- Needle valve and bubble counter with a built-in check valve included
- Dual gauges: cylinder contents and working pressure
- Compatible with any size of CO2 cylinder, thanks to the two-stage construction
- Thread to the UK, European, Japanese and Taiwanese standard (BS341 / DIN477 / W21.8) or CGA320 for North America
The product manual is in our help centre.
Shipping and delivery
Free delivery on orders over €200; otherwise €9.99 in Europe and €14.99 for the rest of the world. Orders placed before 2 PM CET are usually processed the same day — a regulator may need a little longer, because every one is assembled and tested before it ships. Delivery is fully tracked with FedEx: 1–2 business days in Europe, 3–5 worldwide. Customs or import duties outside the EU are charged on arrival. Shipping policy · Returns
