I'm just doing the WC right now...I put my new HM in the breeding trap because as I was cleaning the tank out and started pouring new water in, I noticed it was cloudy...and sort of yellow-brown coloured.
I thought maybe it was dust or debris from the gravel I hadn't washed away, though i had taken the gravel from the 5 gal and put a bit into Claude's tank and had no trouble with it.
And when I finished filling the 5 gal, it's SO cloudy and discoloured. It looks almost like muddy water. :/
So now I did about a 30% WC in the 10 gal, when I go to fill the bucket I notice the same thing. I washed the bucket with hot water before I filled it, but when I poured the water into the 10 gal it looks cloudy.
What do you guys reckon? I don't know if it's safe to put them back in, but they're kinda stuck in little cups right now...
