I don't remember measuring the pH of LFS water before so I'm afraid I don't know what the pH levels are.

It appears that the cause could be increasing pH rapidly over a short period of time. pH runs on a logarithmic scale, meaning an increase from pH7.0 to pH8.0 is a ten time increase. So even a seemingly small increase of 7.4 to 8.1 is a very large change to the tank inhabitants.

Generally, I would advise dosing less first and ideally spend some time to monitor water parameters as you dose to gauge how much the tank actually requires. I find some of the guidelines on these type of products to be somewhat generic and not necessarily applicable to all types of tanks.

When your tank crash(OS crash), its time to cleanup(reformat hard drive) and setup(install OS) again and add new livestock(re-install software).
