Congrats. I added a double tank setup on mine and then any regular double cover will work. However, I didn't like it and ended up getting these and I like them because they stay on the tanks full time, even if I use them at home.
...and WELCOME TO JOF!!! The members here are GREAT!!! There is a lot of GREAT information to be found here. I am sure that you will have information and pictures to share with us... so please do!!
