Is that the same green water from your turtle Dennis?

Is that growing in hard water?

Have you ever done an ammonia measurement on it?
Zebrafish have been shown to tolerate stand high ammonia levels when they are larvae.

I remember when I was a kid in Maryland, we had fairly hard water and I could easily grow great green water there.
Not so much in Oregon (soft water).

Is that the same green water from your turtle Dennis?

Yes it is.  I currently have two 40 breeders with green water.  The turtle moves from one tank to the other about every 2 weeks.  There are also a handful of Gambusia holbrooki in each tank.

Is that growing in hard water?

It is mainly water change water from my other tanks, so it's not really hard.  I do add a bit of well water to it, mainly for the benifit of the daphnia cultures.

Have you ever done an ammonia measurement on it?

I have not.  The green water tanks get a +33% water change every other day when I remove 10+ gallons of green water and replace it with old water change water from my fish tanks.

As the tanks basically get 100% water changes weekly, and watching the health of the Gambusia along with high ammonia levels drastically impairing Daphnia reproduction, I would be very surprised to find that the water had much ammonia in it.  I'll see if I can locate my test kits and give it a test.  I've been wanting to test some of my water softener water to see if it tests at 0 GH too.
