Thanks for the description. I did buy the book. Honest! I couldn't find it and I waited till the very last minute to build the dome in a panic. I knew I was making it a little big when I cut 10 foot pieces in half but I couldn't remember the 57 inches. My error of three inches was multiplied by 8 causing the dome to be two feet larger in circumference. I didn't even bother to measure the 162 inch cross members so I have no idea how far off I was. I'm sure they were way too long. Maybe by as much as a foot. I don't think it really matters as long as it is covered. It just looks really funny and too big.

Do you think it was a mistake in putting the plastic over the filters too? I thought it would help in keeping them extra warm but I suppose it cuts down on the amount of oxygen the fish get.

I was sure that book was going to turn up after I finished the dome but so far it hasn't surfaced.
