Adding Phytoplankton to Ponds & Lakes In The Spring: A Natural Solution to Help Combat Summer Time Nuisance Algae and Toxic Algae Blooms

When spring breathes new life into our aquatic ecosystems, pond and lake owners face a familiar challenge: excess nutrients and the potential onslaught of nuisance algae blooms in the summer months. These blooms, particularly filamentous algae and/or toxic cyanobacteria, can turn a serene water body into an eyesore or sometimes even a dangerous environment for animals and people.

There is a proactive, ecological approach to combat this issue. By boosting the concentration of phytoplankton in your water in the spring time, you are essentially using good algae to compete for the same nutrients undesirable algae thrive off of. This method is modeled for environmentally conscious water managers and Hydralife Institute provides bulk phytoplankton for water managers to utilize.

Understanding the Algae Problem

Before diving into the solution, it's crucial to understand the problem. Algae blooms occur when there's an excess of nutrients in the water, the main two being phosphorus and nitrogen from runoff, effluent waters, or decomposing organic matter from the fall and winter season vegetative die off. When summer temperatures rise, these nutrients fuel rapid algae growth, leading

Potential fish kills
Toxic conditions (in the case of harmful toxic algae blooms)
Unsightly, less healthy waters
Less productive food chains
Undesirable and abundant filamentous algae both in the water oron the surface
Reduced oxygen levels

The Phytoplankton Solution

Phytoplankton, microscopic single celled algae, form the base of the aquatic food chain and are our allies in this battle. By inoculating your pond or lake with beneficial phytoplankton species in the spring, you're essentially giving the "good guys" a head start. Here's how it works:

Nutrient Competition: Beneficial phytoplankton consume the same nutrients that fuel problematic algae including NH3/NH4 (ammonia), NO2 (nitrite), NO3 (nitrate) and PO4 (phosphate). By establishing a strong population early, good phytoplankton can consume and outcompete nuisance algae for these resources.
Ecosystem Balance: A diverse phytoplankton community supports a healthier, more balanced ecosystem. Phytoplankton is one of the main food sources for zooplankton and therefore your zooplankton populations will flourish, in turn, providing abundant food sources for small fish and crustaceans.
Water Quality Improvement: Many beneficial phytoplankton species will increase dissolved oxygen levels, which is particularly important for fish in the hotter months of summer. Phytoplankton can also increase your water's turbidity which can limit the sunlight penetration to nuisance algae and reduce evaporation.

The Inoculation Process

Healthy lake with beneficial phytoplankton

Inoculating your pond or lake is a relatively simple process:

Timing: Aim for early spring to early summer, just as water temperatures begin to rise.
Selection: The team at Hydralife would love to help you through the best option, to discuss algae, quantity and delivery, contact us.
Application: Acclimate the phytoplankton to the temperature of the water and add it directly to a water stream where it can be carried into the pond or lake.
Monitor: Regular water quality testing can help track the success of the inoculation and inform the water manager of any necessary follow-up treatments. Hydralife Solutions will provide nutrient analysis for any of our customers.

Benefits Beyond Algae Control

Spring phytoplankton inoculation offers benefits that extend beyond algae control:

Improved Fish Health: A robust phytoplankton community supports higher trophic levels, potentially leading to healthier and more abundant fish populations.
Natural Water Treatment: Beneficial phytoplankton can help process excess nutrients, acting as a natural water treatment system.
Reduced Chemical Dependence: By promoting natural ecosystem balance, you may reduce the need for chemical algaecides throughout the summer.
Complete Food Chain: By utilizing beneficial phytoplankton, you are providing zooplankton with a nutritious and abundant food source. Zooplankton will consume and help manage phytoplankton while providing a food source for fish fry and other organisms that reproduce in your body of water. Therefore, you will have a vibrant and lively aquatic ecosystem.

A Word of Caution

While phytoplankton inoculation is a promising technique, it's not a silver bullet. It works best as part of a comprehensive lake management strategy that includes:

Proper aeration and circulation
Regular monitoring and maintenance

Conclusion

As we seek more sustainable solutions to environmental challenges, spring phytoplankton inoculation stands out as a promising tool in the fight against nuisance summer algae blooms. By working with nature in a traditional manner, we can foster healthier, more resilient aquatic ecosystems that remain vibrant and manageable throughout the warm summer months.
