Heppy, depending on your goals and abilty to move it... some cedar is better left whole and others cut and bundled. If you've seen the recommendations be sure to add fluffy cover and dense. I cut the big stuff up and bundle it to make dense cover. Lessons learned, use nylon cord to tie it together. I used galvanized fence wire and in less than a year am seeing it rust through. My water is pretty saline though. Just go with nylon. Much easier to work with! My tank was full so we used a drag line, boat, truck and quickish release to move it in place.
Now, put on the long sleeves and get busy!
Here is a pic of my tank with some initial cover. More has been added and more will be. This was the "easy" stuff.
