Thumbs up on Salttanker's book suggestion. The book by Fenner is a great starting place. Also, I've had the stressful experience of moving an established 55 gallon tank from one residence to another. Can be done, but you'll need to get creative with trash cans and have plenty of lifting help hehe. Hopefully you won't be moving it too far. With SW
, bigger generally equates to better, but with your portability requirement that makes things tough. I don't think I would want to try moving anything bigger than a 55, especially knowing that I had to move it again in a couple of months.
