Most of us trust our tap water without thinking twice. It looks clear, tastes fine, and boils up just like any other liquid. But what if we told you there’s more in your glass than meets the eye?
One of the simplest ways to see what’s hidden in your tap water is through an electrolysis test. It’s a striking demonstration that exposes the dissolved solids you normally can’t see.
What Is Electrolysis?
Electrolysis is a process that passes a small electrical current through water. Instead of changing the water itself, it causes the dissolved solids, metals, and minerals inside it to react and separate out.
In other words: what was once invisible becomes visible.
What It Shows in Tap Water
When you run electrolysis on tap water, you often see the liquid turn yellow, green, or even brown. This cloudy discolouration comes from the total dissolved solids (TDS) — things like calcium, magnesium, heavy metals, and chemical residues.
- Green or brown colours can point to metal ions or chemical byproducts.
- Cloudy or muddy textures usually mean higher concentrations of dissolved minerals and sediments.
- Black flakes can indicate iron, rust, or other oxidised materials.
These substances are typically present in tiny amounts, so you don’t notice them when drinking. But electrolysis makes them impossible to ignore.
In our own test, we used tap water that had been boiled through a Morphy Richards kettle, filled with Manchester tap water. When exposed to electrolysis, the sample quickly turned murky and discoloured, revealing the residues and dissolved solids left behind.
The glass on the right, however, contained hot water dispensed through a reverse osmosis system — in this case, Sküma’s MY Station. Even under electrolysis, the water remained crystal clear, demonstrating the effectiveness of RO purification in removing impurities.
Why This Matters
Not all dissolved solids are harmful. Some minerals, like calcium and magnesium, are essential for health. The problem is that tap water can also contain unwanted intruders: industrial residues, chlorine byproducts, or heavy metals from old pipework.
Electrolysis doesn’t tell you exactly which compounds are in your water, but it does highlight the overall impurity load. And once you’ve seen the difference, it’s hard to go back to drinking blind.
How to Ensure Cleaner Water
That’s where reverse osmosis (RO) purification steps in. RO filtration is one of the most effective methods to strip away unwanted dissolved solids, leaving water that’s clear, fresh, and far closer to pure H₂O.
At Sküma, we’ve taken this technology and built it into the MY Station, a countertop system that not only removes impurities with medical-grade RO, but also lets you personalise your hydration with functional infusions.
So, the next time you wonder what’s in your glass, remember: electrolysis shows you the problem. Sküma shows you the solution.
