Couldn't phone the Vet, so the fecal may have to wait a little unfortunately.

However, I'm going to conduct some tests. I'm going to see if I can get the water clear again, by avoiding disturbing the gravel/filter. Also, I'm going to stop handling the toads (Aleksis in particular) during feedings, and avoid stressing them as well. During feeding I tend to handle them (after washing my hands with soap and water, and then dechlorinated water) to ensure they all eat enough and others don't steal others crickets (I feed them individually) but now I'm going to just try and feed them without any handling.
