Using Pond Water for Carnivorous Plant Bogs: Testing and Reverse Osmosis Options

Using Pond Water for Carnivorous Plant Bogs: Testing and Reverse Osmosis Options

Pond water can work if mineral levels stay below 50 ppm and nitrogen is negligible. However, fish waste and decaying organics often raise these levels, causing nutrient buildup in bog soil.

Testing

Use aquarium test kits (hardness, nitrite, nitrate) from a local aquarium supply store. If levels are high, use pond water sparingly or invest in an RO unit.

RO Unit Recommendation

The Merlin by GE (350 GPD, ~$350) is the most cost-effective high-capacity unit we've found. Similar units from other brands cost $700–$900. Search online for a distributor near you.

Good growing!
