Water perimeters are wacko?

My situation:
I recently lost my cleaner shrimp, don't know how or why, all my tests at the time were normal. So, for my step-son's birthday, we ordered him a horseshoe crab. We had at the time a scarlet hermit, a cerith snail, and 2 other unidentified hermits in our 2.5 gallon nano. We ordered the horseshoe crab, a nassarius snail, and 3 more cerith snails. After the ordeal with them, (long story short, the lady I ordered them from never checked her email in the 3 days before she sent them, and we left for vacation. I had emailed her for 3 days telling her to wait to ship them, but she did...they sat at the post office for a week. And when I picked them up, everything was alive.)
She sent 2 horseshoes, 4 or 5 nassarius snails, and about 10 cerith snails. There are 2 others that I think are astreas, but I am not sure.
Now my water tests are messed up...any ideas?

Could it be from the Cleaner Shrimp that died?

no, he was eaten by the crabs rather quickly, and it was about 2 weeks between the death of "Shimp" and the acquisition of these new critters and the water perimeters changing.

That's a lot of inverts for a 2.5 gallon .... don't forget, they generate waste also.

I know that it is, I only wanted 4 more snails and the horseshoe...that is all that I was putting in there. She sent more than I paid for, which would have been great if my tank wasn't so small. I have no where else to put them. blah
