Great, thanks for the info!

I recently learned a friend of mine had an ID shark in a 35 gallon community tank, which was already overstocked. The cat is 2.5 years old and is only about 6 inches. He looks perfectly healthy, but obviously he's been severely stunted. He was visibly stressed and very jittery. My friend also said ...

Great, thank you both very much. I'm just going to leave the pH at the stable 7.8. I really appreciate the help and so do my cats!

The tank is fully cycled if that's what you mean, I know pH swings during cycling are normal. It's been running for about 2 months now. The RTC x TSN hybrid has been in the tank 2 weeks, the TSN has been in for about a week. The pH of my tap is 7.8, same as the tank.

I haven't been using pH ...

Everything I find says that their ideal pH is around 6.8-7. I've seen that they will be fine up to 7.8, but thrive at 6.8-7. I love ...
