Using my sandbed from old to new tank?

[Reef Pilot]

I'm sure most here would disagree with me, but I say reuse your old sand. I would rinse in "used" salt water (stored from a water change). You don't want to kill the "life", just rinse out the detritus. I did that years ago, when I set up my downstairs tank, and the cycle just continued with no ammonia or nitrite appearing. You will get some cloudiness, but a bit of MB7 clears that up pretty fast.

Personally, I think (again contrary to popular opinion) new sand is more risky. There is no "life" in it, and may even contain dead organics which could cause a cycle. And will take some time before it can grow enough life to "digest" detritus.

Nah, I'd agree with you I would simply rinse it as you said in tank water, preserving a lot of the bacteria.

I agree with you as well. I rinse rinse rinse. I find that with new sand I rinse just as much. But as Myka said keep a bit to seed the rinsed or new sand.
Those that suggest all new sand, what do you do with your old sand? Throw it out?

When I used to have sand beds in my tanks I would always use some of the old sand bed to seed the new and the rinsed sand that I was using in the new set up.

I was under the impression that seeding the new set up with sand and live rock from a running system would always speed up or eliminate the time to cycle the new set up.

Good luck Laurie

I rinsed and saved most of my old sand from my last tank to use on my current tank as well as bleaching all my liverock and dried it because I wasn't setting up my new tank for almost 2 years . Now its set up nitrates seem to be an issue that ive never had before and im inclined to think its the sand and rock , even though I cleaned everything as much as I could I had nitrates with no fish in the tank for months and still do .

I always reuse sand. Having moved my garden eel tank I had well over 300lbs of sand I wasn't going to just throw away. That being said I treat old sand exactly the same as new sand. New sand is hell to rinse. Old sand is no different. I rinse it in the sink or outside with the hose if the weather is nice. Lots and lots and lots of tap water. Then rinsed in ro then salt water then in the tank and cloudy like new sand despite the massive rinsing it's rarely enough. If you want to seed the sand keep a cup before you rinse it and add that to the top but imo it's not needed.

New sand, maybe add some old. If you really feel like rinsing then go ahead, I wouldn't bother dealing with. If it's a deep sand bed then it's just going to be a dirty mess. I wanted to go BB but I added a .5 inch of new sand when I started my new tank just for looks.

What about new bagged live sand, has anyone used it?
Yes -No comments please.

Ya Bill that's kinda what I was thinking as well, I think I'm just going to use some of the sand out of the 90 g. I'm using about 50 lbs of live rock from my 90 g and put the sand in last all around the rocks approx. 1/2- 1" deep I'll just do a bit of a rinse with some old tank water before it goes in. I'm hoping to give the new tank a few days and then transfer the livestock. thoughts anyone.
