Well keeping on topic and reef related, I haven't shopped in the US yet except for chloroquine phosphate. I have now got a local vet to write a prescription so I can purchase locally. I would like to travel south for fish food IF I can find a way to get it across the border without ending up in jail. It seems the Canadian government had now made mixed frozen fish foods virtually impossible or unprofitable to import. Specifically I've been looking for Pro-Salt's Angel Diet. I have used this successfully for very finicky new fish as a first food where everything else has failed. Now I can not get it anywhere
The new rules also seem to apply to Ocean Nutritions Angel Blend as well.
So yes, I will cross border shop if I can find a way to import for personal use.
