The AQL-CHEM2 is a 120VAC CO2 dispense kit designed for use with a Goldline Aqua Rite Pro chlorinator or Pro Logic pool control. When used with the AQL-CHEM sensing kit, the AQL-CHEM2 solves the problem of how to provide low cost pH control for backyard pools without having to handle acid. The AQL-CHEM2 is designed to install on a standard CO2 tank and wire directly to the Aqua Rite Pro or Pro Logic. Using the AQL-CHEM sensing kit, the Aqua Rite Pro or Pro Logic will sense the pH level and if needed, the AQL-CHEM2 will inject CO2 into the pool water. CO2 is mildly acidic when dissolved in water and will lower the pool's pH slowly without the safety or health concerns normally associated with harsher acids.
The AQL-CHEM2 includes:
- Pressure reducing regulator preset at 50 psi output
- 110 VAC solenoid valve with 6' power cord
- Nylon washer and spare (only use one)
- 15' of black UV resistant flexible tubing
- PVC check valve injector
CO2 information and availability
The AQL-CHEM2 kit requires the use of CO2 which is supplied in cylinders that are readily available from various sources. CO2 cylinders are offered in a variety of sizes. Goldline recommends the use of 20 pound cylinders for most residential pool applications. The AQL-CHEM2 uses a standard fitting for these tanks. CO2 can be easily found at local and national welding supply or beverage companies. A quick search on the web with the keywords "CO2 supply" will yield many companies, some with hundreds of branch/store locations nationwide.
