Water-thyme is a fully submerged aquatic plant that grows vigorously in ponds, water features, and aquariums, helping to oxygenate the water and reduce algae. Plant bundles weighted at the bottom in 1-3 feet of still or slow-moving water with access to moderate sunlight. Monitor growth carefully, as it spreads quickly and may require thinning to prevent overcrowding.
