I just did my normal H2O change and after I got done, most of my fish started showing distress coloration and 1 of my Rummies died. I use a Python,
and have been for about the last 10 H2O changes or so. At first I thought maybe it was oxygen depletion as they were all up near the surface and the Python
doesn't aerate the H2O. One of my Indian Glass fish has a little white stuff on a fin, so I have been dosing Melafix
for about a week, and just started Pimafix
for the first time yesterday. I have never had a problem with Melafix
in the past. I did just under 50%, and checked temperature before I refilled. The only other change in routine was I used Prime
instead of AmQuel.
Since there's no way to pre-treat the tap water when using a Python,
I put the Prime
directly into the tank before I refill. All my other parameters were good- 0 Ammonia, 0 Nitrite, 20 Nitrate, 0 degrees GH, 8 degrees KH. I don't normally check these before a H2O change anymore as I'm doing weekly 50% changes. The Ph out of the tap was 7.6, and as my tank is normally about that high when the CO2 is off, I didn't check it. (I know, bad move.
) When I checked the tank after I noticed the problem, the Ph was 6.8. It had to be even lower than that to start. Does it make sense that I Ph shocked my fish, rather than it being a problem with any of the products? It's just wierd that some fish didn't react at all, and others did. I did an emergency 6 gallon aerated tap water with Ph and temperature adjusted to the tank, but didn't use any Melafix
All of the fish seem to be bouncing back.
