Should I use the Med Trio?

[lmhicks101]

I got 5 CPDs and 4 guppies from Petsmart and ended up losing 2 CPDs and 3 guppies.  I got some more fish and now I’m considering doing the med trio. All water perimeters are stable and all the guppies were active and eating. They were in a different tank than the cpds. One was a bit skinny but eating and active. Came down stairs to 2 dead and then a 3rd the next day. The 4th is fine though. That was 2-3 days ago. 
 

Is the med trio still recommended and if so then is this article still accurate on dosing and instructions? Sorry it’s been a while since I got new fish. Been obsessed with shrimp the last year so wanting to double check. Also I have maracyn and maracyn 2 so which would you do?

If they are showing no signs of illness. I would use paracleanse to clean out their internal worms.
