Well Water for Carnivorous Plants: Testing and Filtration Options

A grower's husband claims their well water contains only silica and is safe for carnivorous plants. The grower sees bathroom deposits and is skeptical.

Silica vs. Hard Water Minerals

Silica (silicon dioxide) doesn't dissolve well in water. Bathroom deposits are typically calcium, magnesium, and iron – hard water minerals that harm carnivorous plants over time. Even if silica is present, it's often bound as magnesium/calcium silicates, still harmful.

Solution: ZeroWater Filter

A ZeroWater pitcher uses deionization to remove virtually all dissolved solids (TDS). It includes a TDS meter. If your water reads ≤50 ppm, it's safe. Costs ~$0.40/gallon with bulk filters. Available at Target and Bi-Mart.

Test your water first – don't assume it's safe.
