Clyde. You may want to use what comes with the Aquapod for start-up then change things as you go along. The Aquapod comes with a filter block that many hobbyists change out for LR. There are also several mods that can be made to make the 'pod better.
As for white LS and LR, do you have a LFS that you can shop and buy these things from? If you are an internet shopper then
www.marinedepot.com or many of our sponsors can supply these things. Our sponsors are located at the bottom of the forums page, just click on any of the banners. BTW, Happy early Birthday!
