pH Lower - Natural Pond pH Decreaser
UltraClear® pH Lower is a safe, natural way to lower high pH in ponds and water gardens, helping restore balance and improve overall water quality.
When pond water becomes too alkaline, fish and plants can become stressed and biological processes may slow down. pH Lower gently reduces pH levels to a more stable range, promoting a healthier pond environment.
Formulated with fast-dissolving ingredients, UltraClear® pH Lower works quickly and leaves no residue, making it simple to use during pond startups, seasonal adjustments, or regular maintenance.
Safe, eco-friendly, and non-toxic, UltraClear® pH Lower contains no harsh chemicals. It’s completely safe for koi, goldfish, aquatic plants, pets, and pond wildlife.
For best results, adjust pH gradually — never more than 0.5 units in 24 hours. Pair with UltraClear® BufferBlock™ and UltraClear® pH Higher for complete, balanced pond water management.
