This is new 110vt kit with adding 2nd danco. please go to our how to video's to see how to install them.
Option for 30 gal and 50 gal tank. This kit will allow you to add 110 volt pump to any 30 or 50 gal tank of our.
If your going to add 110 pump to your tank we suggest you upgrade your 12v pump to a 700 or 800 pump. Reason behind it you will have issue with 500 once your battery starts to get low. With 700 or 800 you will get more time out of it with battery being low but will eventually also stop pushing hard enough to draw air when battery gets to low.
