Rescaping saltwater tank

Hi, I want to rescape my reef tank now that I can actually get the rocks I wanted since the beginning, I'm also tired of the current look and want something new.

The fish in the tank currently is:
2 Blue green Chromis
2 Snowflake clowns
2 Bangai Cardinals
1 Fire shrimp
And a few coral.

I was thinking of taking water and the filter media from my 300l tank and temporarily place the fish in my 60 cm 60 litre tank which also has a protein skimmer. My question is, is this tank gonna be big enough for my fish for a week or two?

You might get a few more answers on the marine version of TASA, Marine Aquariums SA (link).

Why would your rescape take a week or two? The shorter time your fish and inverts spend in the smaller tank, the better.

60L is a bit of a tight squeeze for all those fish IMO, a little less so if they're all young. Using the water and filter media (and maybe some substrate, too?) will help in establishing a mature biological colony in the new setup, but do bear in mind that you have the same biomass of fish polluting a smaller volume of water. Not only will nitrogenous compounds more rapidly accumulate, but you may have trouble regulating your other water parameters as well.

If you go ahead with this, you'd need to be on top of your maintenance game, so include more regular water changes where you can, check out your protein skimmer cup regularly, and try to check on your water parameters regularly to make sure you're not dealing with too much fluctuation.

Ideally, you could remove your livestock to this temporary tank (still using the filter media/water/etc. transfer), and rescape your tank over the space of a day or two, and then get the fish back into more comfortable accommodations.

Regards,

 

Probably won't take a week, but wanted to be sure that they would be fine so I said a week to be safe. Thanks for all the advice.
