Hi all,
Six months into our new hobby we have decided to upgrade our Red Sea Max 130D (34 gallon) to a 90 gallon megaflow aquarium. The Red Sea is a plug n play tank and the 90 gallon is a custom build.
Few questions:
1. What is the best way to transfer our livestock from the old tank into the new tank?
2. We were told we can literally dump the old tank into the new and will hopefully only have a small cycle. Is this okay for inverts and corals?
3. How are we supposed to efficiently put 60 gallons of new saltwater into the new tank (with the old live sand and the large amount of new live sand) without stranding our fish?

This is very stressful at the moment, thanks for all your help- it is much appreciated! :thumbup:

firt off dont just jump and hope, i would set up most of your new lr and new sand and let that cycle first, you can seed the sand with a little bit of your old live sand or use new live sand i wouldnt use the old sand though, than add your other lr if you want it, than your corals and fish, use new water though in the tank and let it cycle before transferring, also use the same water you mix up for the new tank for water changes with your old one, that way the sg, ph, and other parameters are the same so you dont shock the fish, you can always re trip acclimate them from the old to you new, as always taking your time is better
if you just dump, you dont let the new lr cycle and that would kill off everything else when it does

All you need to do is fill the new tank after you have it all plumbed and equipment running and tested. Then add your current stock and water.

1. freshwater test the system
2. add NEW sand
3. Fill tank with salt water (closely matching your current parameters)
4. let it run over night to reach desired temp etc (leave enough room for your 25ish gallons of water)
5. Next day, put rock in new tank
6. Put livestock in new tank
7. Add the water from your old tank
8. Sit back, relax and let the tank do its thing for the next month or so

Doing it this way, you should have little cycle. if you add base rock, cook it first. If you add live rock, cure it first...

Thanks for responding- just to clarify,
Should we be seeding the new sand bed with some old sand? Or should we just toss it all?
And if the tank does go through a cycle, is this going to be okay for the corals we need to transfer (open brain, sun coral, tree coral, torches and candy canes)
I guess I dont understand how the new tank wont go through a big cycle. Since the volume is tripling, wont the old rock/water/sand have minimal affect on the new parameters? This is equivalent of a 2/3 water change with new sand...right?
(Btw all of our rock is pre cured)
