Tank upgrade

[hentie]

Hi All,

i need some advice.

I am planning on upgrading my Red Sea 240L to a Red Sea 425L.

The 425L is going to stand in the exact place as the 240L (no cycle then in new tank), also because I am using most of the equipment (lights, pump, wavemakers) in the new tank.

I will be using all of the current rock in the new tank, but a new sand (maybe a cup of the current sand).

Livestock:

• Yellow tang
• Striped wrasse
• Diamond goby
• Damsel
• 2xCardinal
• Clown
• Dart fish
• Anthea

Huge nem that has split and now occupies various rocks (taking over tank)
Couple of leathers
Couple of LPS

Any pointers on how I go about this.

Thanks

Add some stability when you move everything over to help settle the tank

Use the old tank water to set up the new tank.
The water is full of beneficial bacteria and micro organisms that help to break down waste, thus maintaining water quality and prevent ammonia spikes.
You can use a filter sock mounted on a large bucket to filter the water (to remove detritus) before adding to the new tank.
Using a product such as Aqua Vitro seed or Seachem Stability will also help to prevent Ammonia spikes.
Get the circulation going as soon as possible.
Some pre-planning will help a lot to get the change over done quickly. Don't try to do it on the fly.
