Transfering tanks.

[Madreefer]

I started out with a 30G to 50G to 72G to another 72G due to a leak than a 90G to now a 144G. Each time I used all of the water from the old tank and half of the sand. I've never lost a thing. If your fast everything should go well but expect alot of water on the floor. If your using dry macro you wont have any spikes at all. Be prepared with lots of rubbermaid storage containers or buckets and have your new sand well rinsed beforehand. You'll be adding alot of new water so in my mind it's considered as a "big water change". I've helped a couple of freinds by doing it the same way and the results were good as well. Good luck and have fun.
