He's doing much better today. When I got home with his medicine he started swimming around to greet me. He's resting atm, so I don't want to push him. He keeps swimming around every so often which is much better than the last 2 days.

The nitrites today after the water change were 0ppm, I think that was what it was on friday, the trouble I had was the nitrates though.

If I use a cuttlebone to soften the water, will it bring down the pH and reduce the alkalinity, it's still high today and I did another 1/2 water change.
