Yes, you should remove the cartridge. See if the instructions here work for your system - Nature2 Fusion - Further Reading

I will do that this weekend. I think, when I opened it I didn’t have a cap so I left it. I will follow these instructions. Thank you for that link

I guess I have been concerned with how the ph will affect swimmers. I was shooting for the 7.4 which I read is the natural ph of our eyes. But if up to 8 is acceptable, I can definitely see saving some cash and time spent on MA

Your tears do not have a TA of 80. You cannot maintain a pH of 7.4 in many pools due to the TA. Any pH in the 7's is equally good.

What is the pH and TA of your fill water?

Do you have an autofill on your pool?

Low pH bothers swimmers. pH of 8 will not be noticed.

Thanks for these articles. They seem to be written specifically for me lol. Looks like my pool seems to want to be at 7.6-7.7. I will keep that in mind and aim for those.

Don’t know that. I haven’t had to fill except when I exchanged water. I will test my water to find out. I do not have an auto fill.

The bottom line is: 7.8 is good. The more you try to control by knocking it down the more it'll play. With the TA of 80 your good in the mid to high 7s and will remain ther longer too. If you're not a SWCG then you don't want a massively high CYA either.
