SG Question

[Rich_Fray]

What would cause my SG to increase over time? My evap water is replaced with RO/DI. I would think that due to salt creep, if anything, SG would go lower over time.

accumulation from additives, other processes-

How much has it gone up? How are you measuring it?

additives are kalkwasser, some Pro DKH Alk supplement, some SeaChem Reef Advantage Calcium.

What did you mean by processes?

[Randy Holmes-Farley]

The alkalinity supplement and reef advantage calcium bring in sodium, chloride, and other ions that will slowly raise salinity.

Do you really mean 1.04 to 1.026??? If so, why did you have it so low to begin with?
