Rex Grigg Style Co2 Reactor | Advanced Version With By-Pass Valve
This style reactor is one of the most efficient methods for diffusing co2. The advanced reactor with bypass is efficient for tanks well over 100 gallons and high flow filters such as fluval fx5/fx6. The reactor is designed to be used between the canister filter and the tank on the output side of the filter. It should be mounted under the tank and needs 18-24" of vertical space. Water should enter the top of the reactor and exit out the bottom. If you have any questions about the use of this style reactor please make sure to contact me prior to purchasing.
The major advantage of the Rex Grigg style reactors, other than near 100% dissolution of co2, is that they require almost zero maintenance and nothing visible in the tank.
When ordering please choose the tallest size that you can fit under the tank, the taller/longer the reactor is the more co2 it can efficiently dissolve. Also make sure you confirm the inside diameter of the output tubing on your filter.
*****The actual length of the reactor will be +/- 0.5", if you have a very tight fit please let me know prior to ordering*****
Color of the reactor: The standard color is black. I can paint it other colors for an additional cost. If you would like a different color be sure to check that option above. Then please include the color which you would like it painted in the comments section while checking out. Please only standard colors, I will do my best to match the color that you want but I can only guarantee that it will be close.
-Mount the reactor vertically(long side up)
-The water should enter the top and exit the bottom
-Start with the valve closed(parallel to the ground)
-When all the hoses are connected(filter and co2) run the reactor for 24 hours before making any changes
-If after 24 hours you are getting co2 bubbles out of the return pipe, open the valve slightly, then wait for 24 hours
-Repeat the previous step until you are no longer getting co2 bubbles pushed out of the reactor
