And im stumped about what to do with the sand. Some say you must use old sand for bacteria etc... some say use new sand to keep from creating toxins in new tank. I just wanted to see what everyone would do. Happy Reefing!
With new sand you need to cycle. If you decide to reuse the old sand, it has already the bacteria and stuff to produce ammonia for cycling. I don't think you need to rinse it. Either way, you have to wait until the sand is stabilized and cycled. The thing is, you need to have the new tank ready before disturbing the old tank. With that said, it is a common sense to use new sand to the new tank seeded with old sand to facilitate cycling.
Did you say you already moved all the tank inhabitants to the new tank and seeded with sand from old tank?Ended up buying new sand and just seeding with old. But, I treated old water like liquid gold and got every drop I could. 72 hours in now, fish are happy corals are happy, and im happy. The only thing I worry about is my sea cuc. he seems to be having a hard time finding detritus, and I dont want him to starve.
