You may want to put in some shells in the tank. That may keep the PH

I learned my lesson the harrd way. I was trying to lower the PH in my
tank and it kept bouncing back. Finally some people told me about the
shells I kept in the tank. I took them out and the PH came down
without any big effort.


No, have not injected CO2. KH is around 170-180. GH is about 100.

Thanks,
