This ISTA Twin Gauge CO2 Controller pairs a German-made solenoid and precision needle valve for stable, accurate, rust-resistant CO2 delivery.
Cautions

What ISTA publish for the I-580 Twin Gauge CO2 Controller:
Type twin gauge, pressure-reduced CO2 controller with solenoid
Gauges two: one reads the pressure remaining inside the cylinder, the other reads the reduced output pressure
Solenoid German-made, with safety valve
Needle valve precision, for stable and accurate CO2 output
Body stainless steel, anti-rust
Connection hand air-tighten, no tool required
Cylinder type face-up CO2 aluminium cylinders
What ISTA do not publish for this model:
Those rows are simply not on ISTA’s specification sheet or in their catalogue, and we would rather leave them blank than print a number we cannot source. If one of them decides your purchase, ask us and we will measure the stock item before you order.
What the second gauge actually buys you. The cylinder-pressure gauge is the one that tells you how much gas is left, and on a CO2 cylinder that reading stays almost flat until the liquid CO2 is gone and then falls off a cliff. It is an end-of-life warning rather than a fuel gauge, which is precisely what you want, because the alternative is discovering the cylinder is empty by watching the plants.
Face-up cylinders. ISTA build this model for CO2 aluminium cylinders that stand upright with the valve on top. Their face-side range is a different fitting for cylinders mounted on their side, and the two do not swap.
The solenoid is the whole point, and a timer is what makes it worth having. ISTA’s own instruction is to connect the controller to a timer, which gives you automatic CO2 injection: gas on an hour before the lights, off an hour before they go out. Without a timer you are turning a needle valve twice a day by hand, and plants respond to consistency more than to any particular bubble rate.
ISTA state it works with their bubble counter and check valve series: that is their own wording, and it covers the 2-in-1 metal bubble counter and check valve as well as the 2-in-1 diffusers.
Confirm the solenoid voltage with us before you order. The solenoid is a mains-powered valve and ISTA publish no operating voltage for it: not on the product page and not in the catalogue. That is a real gap for a device you are going to plug into an Indian socket and drive from a timer, so ask us and we will check the unit in stock rather than have you find out on the bench.
The cylinder, timer, check valve, CO2 hose and diffuser are all separate purchases. A first CO2 setup needs at least a cylinder, a check valve and a diffuser alongside this unit.
ISTA publish no itemised scope of delivery for this product; the list above is assembled from their own product page and catalogue entry. If something is short in the carton, tell us inside the 7-day return window and we will sort it out.

Fits perfectly to the ista co2 face-up cylinder. It’s hand tightened you don’t need tools for this. Looks pretty convincing. And I must say nice, punctual & quality delivery by Indiefur as always.

This is a fantastic cylinder. Looks so stunning. My planted aquarium is placed in the drawing room. This beautiful cylinder gives a different look. This cylinder is full & of best quality. I recommend this cylinder to planted aquarium owners. This will last in my opinion for around 10 months with 2 bubbles per second.

The gauge is of best quality & the precision valve works very well. I am having a local pressure gauge. There is no comparison with that & the ISTA one. The quality is excellent.
