- PROFESSIONAL DIY KIT! A complete system in 2.5L size bottle, that includes SUS304 stainless bottle, regulator, precision needle valve, and easy adjustable bubble counter
- SAFE! The bottle body is made of 1.5mm thick SUS304 stainless steel (25% thicker than normal 1.2mm bottle). It can sustain pressure up to 80kg/cm2(or 1137 PSI). Safety valve will open automatically when the inside pressure exceeds the safety threshold
- NEEDLE VALVE WITH BUBBLE COUNTER! High precision, aquarium specific needle valve provides accurate fine-tuning. Steady 1 bps is achievable. Bubble counter with check valve built-in. It stops water from back flowing into your CO2 tank (protects your CO2 tanks from rust and corrosion)
- OPTIONAL: 12V DC SOLENOID! Having the solenoid on a timer, you can specify when you want CO2 injection ON and for how long
- ATTENTIONS: Solenoid NOT included, need order separately. Citric acid and sodium bicarbonate NOT included
- ✔ INCLUDES EQUIPMENT NEEDED TO DO IT YOURSELF --- In order to build an effective and efficient pressurized CO2 system, there are a few pieces of equipment that are absolutely necessary. The SunGrow DIY CO2 Generator Set includes two caps (that perfectly fit common PET plastic bottles), needle valve, check valve, a pressure gauge, a 3-way connector and 6 feet of 6mm tubing. You simply have to use 2 carbonated beverage bottles, a reaction material and connect it to a diffuser.
- ✔ GENERATES ESSENTIAL CO2 FOR A HEALTHY HABITAT --- Fish and aquatic pets release cO2 when they take in the dissolved oxygen from the aquarium water and plants absorb that co2. Carbon dioxide is essential to the photosynthesis process and sometimes fish alone do not generate enough Co2. A pressurized DIY CO2 system adds the needed gas to your water.
- ✔ COST-EFFECTIVE & SAFE TO USE --- Instead of spending hundreds of dollars on expensive CO2 diffuser set-ups, save money by creating your own do-it-yourself CO2 generator. The basic principle behind the pressurized CO2 diffuser kit is to create a continuous supply of pure carbon dioxide by causing two different liquids to create with one another. The DIY solution is a cost-effective and satisfying way to add essential CO2 into your aquarium water.
- ✔ EASY TO READ, SPECIALIZED PRESSURE GAUGE --- The SunGrow DIY CO2 Generator Set comes complete with a high-quality, specialized pressure gauge. The metal pressure gauge clearly shows the level of CO2 gas on a scale which indicates a safe area. An accurate CO2 reading gives you the chance to make adjustments or relieve pressure before there are any negative effects on your aquarium inhabitants.
- ✔ CREATE HOMEMADE DRINKS AS AN ADDED BONUS --- Obviously the DIY Pressurized CO2 Kit is designed to add and control the amount of CO2 available to your fish and plants, but there is a bonus to creating your own CO2 generator. Instead of using baking soda or vinegar as your reaction material, use yeast and grape juice (or yeast and malted barley) to create homemade wine and beer.
- The CO2 DIY kit is with ABS engineering plastic cover, with locking pipe device to ensure non-deformation, non-loose, non-slip wire when working.And it's with professional metal material gas adjusting valve to ensure pure CO2 DIY
- According to the pressure principle,to push the acid liquid into the small soda liquid,the two liquids reacting to produce continuous PURE carbon dioxide
