Is spring water safe for opae ula?

Hi, wondering if I can use, Crystal Geyser natural alpine spring water, to top off my opae ula.

The answer is No.

Extract from Mustafa article:

"It is important to top off with distilled/reverse osmosis (RO) freshwater periodically to replace water lost to evaporation."

The issues with spring water is it will contain minerals which includes sodium, calcium, magnesium, and potassium. What you get from using a marine salt mix is all you need. Stick with distilled or RO.

Oh, ok thanks! also, Do you know which brand is good and do I need to use anything before or after topping off?

[Jim177y]

Depend on your country super mart, brand doesn't matter as long as it's distilled water (zero content).

Use a hydrometer to measure the salinity level a few hours after you top up, ideal range is from 1.010 to 1.012

Am I able to use a refractometer?

[Jim177y]

Yes but not recomended.
