ammonia-0.25ppm
nitrate-80ppm
nitrite-0ppm
temp-81

Thanks Kristian.

The new rock has thrown off the balance of your tank.
It's started a mini cycle, I'd say your best off on judt doind water changes until it comes back down.

is there anything to speed this proces up?

The water changes are about all you can do.

Do water changes with RO or RODI water, you are definately getting die off from the new rock, you should always cure rock before adding to an existing system, or add dry rock that won't spike your tank.

If anyone can hold your livestock for you, (ask here, and your LFS) that would be a good idea, because ammonia and nitrates that high are going to kill your stuff off.

Water changes are best, but if you are really worried there are amonia sponges you can get that will absorb some of it.

how often (water changes ) is too much?

Take your livestock out of that tank and into a quarantine/temporary tank with new clean water, and let your tank cycle properly.

Depending on your livestock, you might also consider pulling some of that new rock out to some rubbermaids and cycle it on its own. You can slowly add it back to your main tank without a cycle if you add it slowly.

With the new rock out and more water changes, the ammonia should settle. Then you can sort out things separately with no risk to your livestock.

Along with the water changes, you could also trying putting some synthetic absorbent, such as Seachem's Purigen, in your sump or a canister filter (of some sort) attached to your tank.
