CrystalClear Thrive Pond Plant Food Tablets — 200 Slow‑Release, Fish‑Safe Fertilizer for Lush Foliage & More Blooms

CrystalClear Thrive is a fish-safe, slow-release pond fertilizer in tablet form that delivers balanced nutrients to container and planted pond species for stronger roots, fuller foliage, and more abundant blooms.

Designed for water gardeners, Thrive comes as convenient tablets that release essential elements over time so aquatic plants receive steady feeding without frequent dosing. The formula combines nitrogen, phosphate and potash in a measured ratio to support leaf growth, flowering and root strength. Because the tablets are formulated for aquatic settings, they can be used around koi, goldfish, frogs and other pond life when applied as directed.

How does Thrive help pond plants perform better?

Thrive supplies a trio of key macronutrients—in proportions targeted for pond-grown plants—so they get the building blocks needed for lush foliage and prolific blooms. Regular insertions of tablets keep nutrients available at the root zone rather than diluted in open water.

• Contains 10% nitrogen, 14% phosphate and 8% potash for balanced nutrition
• Slow-release pellet form delivers steady feeding over weeks
• Targets roots in container and potted pond plants for efficient uptake

Is this fertilizer safe to use around fish and other pond life?

Thrive is formulated for aquatic environments and labeled for use with fish, amphibians and invertebrates when you follow dosing instructions. It’s intended to feed plants at the root zone so nutrients won’t spike in open water under normal recommended use.

• Designed to be safe for koi, goldfish, frogs, snails, and similar species
• Place tablets into soil or planting media, not free-floating in the pond
• Follow application frequency and tablet counts to minimize water nutrient shocks

How often and how many tablets should I use for common pond plants?

Application frequency and tablet count depend on pot size, plant type and water temperature. Thrive is intended for monthly or every-2–4-week placement when water temperatures support active growth.

• Use 1–2 tablets per gallon of planting media for general potted pond plants
• Water lilies: 1–2 tablets per plant placed in the root zone
• Lotus: approximately 4 tablets per plant for larger tuberous root systems
• Apply when water temperature is above 75°F for active uptake

How do I apply the tablets safely and effectively?

Place tablets directly into the aquatic potting mix or planting media and press them in so they remain anchored. Reapply at the recommended intervals and avoid adding extra tablets beyond guideline to prevent nutrient imbalance in the pond.

• Push tablets into soil at the base of the plant to target the roots
• Replace every 2–4 weeks during the growing season or monthly as directed
• Measure by gallons of planting media to keep dosing consistent

Who this is for: CrystalClear Thrive is for water gardeners who cultivate containerized pond plants, hobbyist koi keepers who want to improve plant health without stressing aquatic animals, and anyone creating water-feature displays with lilies, lotuses and marginal plants. It’s especially useful for those who prefer a low-maintenance, root-targeted feeding method that avoids frequent liquid dosing. Use the tablet counts and timing provided to maintain a balanced aquatic environment while encouraging vigorous growth and abundant flowering.
