your PH is alittle low there ...you need to get it up to about 8.2

Hello SGH
Sorry to hear that your Cardinal isn't feeling up to par.

When you have the chance if you would be so kind as to update your profile aquarium information it will be a great help.
Thanks!

Sorry for your loss Sadly it does happen. How are the rest of your fish? G Don is right your at a neutral level needs to be around 8.0 -8.4 as a safe zone whats your alkalinity level?

It's kind of hard to say what natural is for cardinals...i have 2 healthy specimens that spend most of their time just floating in the back of the tank until evening. They are nocturnal so it's hard to see when they're happy....sorry he passed.

Between 9 and a 11 is good 12 is okay but don't let it get any higher.
