Thanks for the posts. I used salt in cups, placed it in the tank and let the salt slowly disolve. I've been told to do this by a number of people as it's slow.

I had the water tested at Pisces in Calgary.

I'm not sure about oxygen but there's a air pump attached to a blue ball that does tons of little bubbles, I've got a Eheim pro filtering the water and getting good flow and we bought a powerhead a month or so ago to have good flow. I thought that was all enough to keep the oxygen levels up.

Thanks again for the reply.

One GSP left, he actually ate some snails today and bloodworms, but he looks grey and unhappy and the one mono, laboured breathing and not eating still.

Gotta go, will give more feedback on water changes, my ride is here.
