Sick Molly

[An t-iasg]

You are certainly not an idiot! You are very dedicated to the well-being of your fish.

Your water changes look like they are getting things back on track. It's great that the molly is doing better.

Joann has a great idea - squeeze the old cartridge onto the new to save some bacteria when you change it out. Old carbon no longer functions as it should when new, but it can become a reservoir for good bacteria. That's probably what happened in your case. It doesn't absorb ammonia either (like J. said, there's some specific ammonia-removing media for that, which a cycled tank doesn't need). The carbon cartridge with no other media for bacteria to reside is a reason I'm not fond of Eclipse filters. The bio-wheel holds bacteria, but I think a sponge-type media is better. I tried to use floss and a sponge in place of the carbon cartridge but the sponge blocked the bio-wheel flow and the floss got pulled into the bio-wheel. If you're handy, you could rig up some media in the carbon cartridge tray area. Maybe try a little pantyhose toe with bio-stars. Or just continue to use the carbon cartridge as you have been doing but try to save some of the bacteria from the old to new.

Thanks again, I will squeeze the old filter in the future.

Also, thanks again for the feedback, I did a recent test after the second 75% water change and the colour of the test dropped about two shades, so I think I got it to 0.50ppm.

I will do another WC tonight, let them relax a bit after the one I did 2-3 hours ago. Don't want the pregnant Guppy to abort or have complications, she's starting to hover near the surface.

After the third 75% water change, I got the Ammonia down to 0.25ppm.

The Molly is doing fine still, definately looking like his normal self again. But noticed my Guppy has her tail nipped up a bit, one of the baby Mollies seems to be picking on her at times. Might have to QT her when I get this water down to 0 Ammonia so I can transfer water to the QT.
