What's the volume of your tank? Which salt are you using?

For example; IO is around 1100 ppm, so every time you do a water change you're going backwards unless you add Mg to the freshly mixed saltwater.

My system has a total volume of 40gallons.
I use reef crystal for my salt!
I used to use reefers best salt,best salt I've ever used but now I'm on a tight budget.

When I make saltwater for a w/c I test it for alk, Cal, and mg. If anything is out of whack, I just top it up using a reef calculator and chems from my dosing containers.

IO is only 1100ppm still? based on my test it's around 1200ppm, based on my expired Salifert anyway.

My tank sat at 1140 for years with IO, so somewhere in that range.
