tank change

also, when Im doing the change in subtrate, when my rocks are already out I just put enough water to fill up the bucket for the fish and rocks and then what do I do with the rest of the water in the tank? keep it in the tank or siphon it out and put new water in?
 
I changed a 40 long aquarium that I'd inherited care of for a 50 Long last winter. The 40 turned out not to be an aquarium, but a reptile tank and the plastic bottom was sagging ominously. Here's the proceedure I used:

1. Mix 25 gal of clean saltwater the night before.

2. Fill my 10 gal with tank water, and start filter for circulation. Corals were tranfered to the 10 gal.

3. Fill rubbermaid tote with water and move live rock to it.

4. Remove fish from now half empty tank with nothing but gravel subtrate (made them easy to catch). Transfer to 10 gal tank with corals.

5. Finish draining old tank and remove with old crushed coral substrate.

6. Set new tank on stand, move live rock to new tank, and partially fill with water that the live rock was in.

7. Add new clean sand for shallow sand bed and finish filling with clean salt water. Let filters run for a couple hours to clean cloudyness from sand.

8. Aclimate corals and fish and return to tank.

Took about 6 hours total, didn't loose a thing and no ammonia or nitrate spikes afterwards.

i have a 10 gal. and a 20. gal tank not in use right now so I would fill the 10 gallon with corals and fish, fill the 20 gal. AND a bucket or 2 with rocks because the rocks are too big to fit all into a 20 gal. then I would still be left over with some water in the tank so I would leave the extra water in the tank, switch substrates, add rocks. Now when I add the fish again, should I acclimate them like i was buying them? (put in bag, sit for an hour). After fish and corals were added I would put the water from 10 gallon and 20 gal. that i filled earlier with the 75 gal. tank water and put it back into the 75. Does that sound about right or did i mess something up??
