Green water and stringy algae are usually a nutrient problem more than a chemistry problem. Nualgi Ponds is built to work on that principle. It's a nano silica based treatment carrying a patented formula of 12 essential elements, and instead of poisoning the algae directly, it feeds a bloom of diatoms that out-compete nuisance algae for the same food source. Once the diatoms win that race, the algae runs out of what it needs to grow and dies back on its own.

The bottle has a 3 year shelf life, so it will keep through a winter in the garage without going bad.

What's Actually In The Bottle

Nualgi Ponds is built on a nano silica base combined with a patented formula of 12 essential elements. Silica is the ingredient most algae treatments skip, and it happens to be exactly what diatoms need to multiply. Feed the diatoms and the algae gets starved out. That's the whole mechanism in one sentence.

What You'll Actually Notice

Algae Starves On Its Own

The diatom population that grows after dosing consumes the excess nutrients sitting in the water column, the same nutrients that would otherwise feed nuisance algae. With nothing left to eat, the algae dies back without scrubbing or a chemical treatment.

A Cleaner, More Oxygenated Habitat

Diatoms release oxygen as they grow, and that oxygen goes straight to your fish and to your biological filter. Zooplankton feed on the diatoms, and fish feed on the zooplankton, so you end up with a small working food chain in the pond instead of a stagnant one.

Noticeably Better Water Quality

More oxygen means the aerobic bacteria living in your filter multiply faster and break down fish waste and leftover food quicker. Cloudy or smelly water tends to clear up as that bacteria population catches up to the workload.

Healthier, More Vibrant Plants

The same 12 elements that feed the diatoms also feed your aquatic plants directly. Color and growth on marginals and lilies usually pick up once that micronutrient gap gets filled.

Fewer Water Changes

Better biological filtration combined with less algae pressure means the water holds up longer between changes. It won't get you out of water changes entirely, but it takes some of the load off your regular maintenance schedule.

How Nualgi Ponds Works In The Water

Dose the pond and a diatom bloom typically shows up within 3 to 5 hours. The diatoms compete with nuisance algae for carbon dioxide, nitrogen, phosphorus, and other nutrients, and they win that competition fast enough that the algae starts dying off. Some of those nutrients get locked into diatom biomass, which then becomes live food for fish and zooplankton instead of fuel for more algae. The oxygen the diatoms produce feeds your bacteria colony, which cleans up waste faster and helps knock down odor along with the green water.

Coverage Per Size

Nualgi Ponds comes in five sizes. Here's how far each one goes.

Bottle Size Gallons Treated
60 ml 60,000
125 ml 125,000
250 ml 250,000
500 ml 500,000
1 L 1,000,000

Smaller bottles make sense if you're trying Nualgi on a small backyard pond for the first time. Larger bottles make more sense if you're running a bigger koi pond or dosing all season long.

How To Dose Nualgi Ponds

Know your pond's volume before you dose. That's the one step people skip, and it throws off everything after it. Nualgi Ponds is dosed at 1 ml per 1,000 gallons per week in ponds carrying algae, ideally applied early in the morning. For ponds under 5,000 gallons with decent flow, pour it straight into the skimmer, the waterfall, or another area with good circulation. In larger ponds, dilute the dose in a jar of pond water first and walk it around the perimeter so it spreads out evenly.

Heavier Algae Buildup

If algae covers about 20% of your pond, dose every 5 days instead of every 7 until coverage drops to around 10%. Once it's down to that level, go back to the standard weekly schedule.

Cold Weather Adjustments

Bacteria slow down as the water cools, and your dosing schedule should slow down with it.

Water Temperature Dosing Frequency
Above 50°F Every 7 days
40°F to 50°F Every 14 days
Below 40°F Once a month
Below freezing Hold off until water warms

If your pond freezes over, Nualgi Ponds won't do much until the water temperature climbs back above freezing.

One more thing worth knowing: turn off any UV clarifier or Iongen ionizer while you're dosing. Both will interfere with the diatom bloom you're trying to grow, so switch them back on only after the dosing window has passed.

Bottle Size Gallons of Water Treated Cost to treat 5,000 Gallons

125 ml 125,000 $1.80
250 ml 250,000 $1.50
500 ml 500,000 $1.20
