Is this scale in the pot?

It's pretty safe. It's in flea and tick product I use on my cats. Just be prudent.

Which one do you recommend and any ideas of where to buy it?

Bayer 3-in-1. You should be able to find it online.

Should be at any big box store too. Also consider adding Azamax to your stockpile. It's organic and does a great job. Probably not on hard shell scale though.

Just an observation, Bayer has changed the names of its products, and you really have to look at the ingredients and percentages of ingredient to know what you are getting. When I go to hardware stores and even in plant nurseries, I now find Bayer products more tailored to outdoor plants, with the insecticide combined with fertilizer and designed to be rain-resistant.

As a follow-up...I did clear up my pots using Bayer and Azamax and am now dealing with what looks to be a persistent mite issue (Bayer is of little use for that). So if it isn't one thing, it's another!
