The major advantage of this style reactor, 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
Note: For people with higher flow filters which use 1″ tubing such as the fluval fx5/fx6 filters, I would highly suggest choosing the 24″ long reactor. People using the fx4 would still be best choosing the 24″ version but can get by with the 22″. The reason being the longer reactor can handle higher flow.
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
*Shipping for Rex Grigg reactors is via FedEx or USPS ground shipping
*Because the Rex Grigg reactor is a custom build piece there is a 1 week lead time before these will ship.
