can't maintain alkalinity

[Jason McK]

It's going to be very difficult to bring ALK up with your Reactor. I would get a large box of Bakeing soda and Boraxo mix it 2 parts Bakeing Soda to 1 part Boraxo and dose that to get your ALK back in line.

I would also check your salt in a fresh mixed batch of Water measure the ALK there to ensure you are starting off right.

You should use your Reactor to maintain CA and ALK not to raise it

yup...that's the truth i guess! get my parameters straight in my tank and in my change water then i suppose the reactor will be able to maintain...

Having a low magnesium level will likely affect this as well, try keeping magnesium at 1350-1400.
