frag tank questions

[mfinn]

I am going to be setting up a 20 gallon tank that might be a future frag tank.
The immediate purpose is just a holding tank for a few months for some LPS and zoanthid colonies.
I'm moving them out of my 66 gallon tank and moving it a file fish.
I only have a few lbs of live rock I can add for biological filtration.

So how much in the way of water changes would I figure I should do?

There will be no fish, just corals.
2- King Spawns
2- Torch Corals.
3- Frogspawns
A duncan colony with about 20 heads
3 zoanthid colonies.

I'm not planning on doing any feeding during this time.

I have a fairly new 20 AIO that holds about 17 gallons. I do 2 gal water changes per week, but the tank is still going through the uglies (dry rock) I have 2 small bengai cardinals and a sally light foot crab in it. when it gets stable I will probably drop back to 1 gal per week
