## Description

MagTool 2.5-4L Aquarium CO2 Generator System Carbon Dioxide Reactor Kit with Regulator and Needle Valve

Review: This is a very solid setup. I have a couple similar products from different manufacturers/sellers and in comparison this product is of better quality. But the thing that really stands out is the two outlet design.
Review: Ordered the 4L kit with 2x outlets. Kit looks very well made, however it came with the wrong plug/no plug adapter so that you cannot plug into an electrical socket. Ordered a replacement - will update. Update - 7/21/2023 Replacement received. Unfortunately, only one of the power plug/solenoid boxes contained an adapter to fit into an electrical socket. Seems like there is an issue with making sure these are provided.

## Features

- 4 Liter Capacity. That is 2x larger than the size of our compeors’ CO2 generator systems. Holds 600g-800g of citric acid and sodium bicarbonate, aka baker soda powders.
- Professional 2x outletCO2 Kit with all accessories need, DC mini solenoid x2 / Precision needle valve x2/ Bubble counter x2/ CO2 diffuser x2/ CO2-graded tubing / Plastic funnel and measuring cup.
- Safety! The wall of the bottle meets the safety requirement - 1.5mm thick SUS304 stainless steel. It can sustain pressure up to 1137 PSI (80kg/cm2). The built-in safety valve will open automatically when the inside pressure exceeds the safety threshold.
- 12V DC Instead of AC Power. DC solenoid runs on very low voltage and generates almost no heat. The solenoid is warm to touch and is super quiet. No humming noises.
- Attentions: The required powders to generate CO2 gas are NOT included! You will need citric acid and sodium bicarbonate powders.
