75g to 125g Build.. What to do?

[Rogerscody17]

Remodeling the house, setting up a 125g tank with a 50g sump, aprx. 170g of water..

75g tank has no sump or skimmer. 5 gallon canister. Aprx 75g of water.

Moving time: 2 weeks.

I was thinking, keep the sump under with everything not plumbed for the first month. So it's only a 125g tank with a fx6 canister.

Questions.
1) what is the best way to add the extra water?
2) should I do big water changes for the next 2 weeks to fill up the 125?
3) should I use my friends water waste to fill it up faster?
4) how long before safe to all fish, coral(sps,lps, softies), and ivtb.?
5) if this doesn't work out and my tank crashes, who would like to pick it up for free? Lol jk...

But on a serious note.. This 125 is going just across the room from my 75g.. I have almost 2.5 grand worth of JUST coral... I want this the SAFEST, and Fastest.

Thank you everybody!

If you're just increasing the volume, you can do that with water that matches the parameters of your current tank. You can use your existing water and just supply the needed additional volume. Moving substrate is a different story and generally not recommended unless thoroughly rinsed with seawater that again, matches your tank parameters, in order to preserve some of the biology. You more than likely will still get a cycle.

Not knowing whether you'll be adding more rock and whether it will be live rock or dry rock, you might want to cycle the new tank. Since you'll need to have a holding vessel for the livestock to accomplish most of this, and it appears you can move them at your convenience, cycling the new tank probably isn't a bad idea, especially if you are going to be adding more rock. You can add your existing rock, if any, sometime later in the cycle to help it along. This is how I upgraded from a 50g to a 200g.

I've moved livestock from a 110g to a 150g. I've heard and agree that the most success comes from moving everything quickly. If you have a setup that is running well and transfer everything to another setup that is up and running well, your survival rate will be greater than if you temporarily store livestock in a moderately run container/sump/tank. Use all the water you can from the old tank into the new tank. This will help stabilize and acclimate livestock, especially if you transfer them from tank to tank immediately.

Be very careful, going to get a cycle moving the crude all around.

Could he move the sand from the existing tank to the new tank (full of fresh salt water) and let the sand cycle the tank, then move the rock, fish and remaining water over?
