How would you acclimate any corals for a tank that small? Sorry for the noobish question but I am thinking about setting up a 5g reef only tank and have been trying to figure this out.
This is taken from another post of mine from earlier. This will work for your 5g tank fairly well. For a .75 gal tank all your corals will be very small frags anyway so I'd try to do the same just on a smaller scale.
Now let's talk about acclimation procedures....Lots of folks make the switch from fresh water to salt water, and so they have the idea that floating a bag for 20mins-hour and then releasing the new critter is the correct way to acclimate them. This may work 90% of the time for freshwater, but you've got more chemical balances to worry about with saltwater, and it's simply not an acceptable way to acclimate your new purchases. When you do a float and release, all you're acclimating your new critter to is temp. What about salinity, and ph for critters? Big swings in these can kill them very quickly. If it doesn't kill them immediately it can add to their stress levels, which are already high from being caught out of the tank in the LFS and put in a bag, etc... When you're talking about corals, you have salinty, ph, calcium, lighting, etc.. to consider as well. This is why some corals don't open for a day or so when they're added to a new tank. I will tell you that I HAVE floated and released corals and even fish/inverts when I was in a hurry, but at least I knew I was running a risk.
So here's what you do. Get a length of airline tubing that's long enough to go from the top of your nano to a bowl big enough for your new purchase sitting next to it, but lower than the surface. You put the airline in the tank, the other end should have a small plastic valve on it like these.

You can ususually find these anywhere that carries fish or airline tubing.
You dump your new critter, and as little water as will cover it in the bowl.
Start a siphon from your tank dripping through the airline tubing into the bowl. Use the valve to adjust the flow so that you're getting at most a couple drops per second.
That's it. You may want to nearly fill the bowl, empty most of it back into the nano and repeat the process again before dumping the new guy into the tank. I usually do the first batch of water pretty slowly, then do the 2nd run at a much faster drip rate. This will give the new addition time to acclimate to ALL of your tanks parameters.
