Only a week ago I transferred my two red eared sliders to a preformed pond enclosure, cleaned the filter, added common goldfish from the pet store to the water -- Not adding the water they came in into the pond obviously. I noticed both had a dull white smudge/blotch on their plastron and tiny white hard bumps on their carapace, and I can't manage to pick them off. No dents or bad smells, clear eyes, clean water. Same diet besides one night of goldfish binging. Could they be calcium deposits?

If you have exceptionally "hard" water, it could be calcium deposits, but you would likely have noticed it prior to or during the transfer. Have the water tested to be sure. Dry dock them for 2-3 hours a day for the next few days and see if that makes a difference. You can use a soft bristled brush and some diluted chlorhexidine (Hibiclens) to gently scrub the shells before dry docking. Continue to monitor for lethargy, decreased appetite and softness or pitting on the shells. See your veterinarian or a vet experienced in treating reptiles for a physical exam if necessary.
