I have stuck with the same salt. The last batch created a white film in my RO storage container. I thought it was salt residue but it isn't. I have no idea what it is but am concerned. Therefore I would say no guarantees
- Pick one brand of salt and stick with it, when you need to dose only dose to match the parameters of the salt - don't alter the salt to the parameters.
- Test regularly and with the same procedure/protocols each time to minimize variance in test results
- Resist the urge to change things like water parameters, light settings (schedule/intensity)
