The Phosphate Absorption Rates of Hydralife's Phytoplankton: To Inhibit the Development Of Toxic Algae / Cyanobacteria / Harmful Algae Blooms / HABs / Blue-Green Algae
Updated: Sep 2
The following includes phosphate consumption for some of our phytoplanktons. These phytoplanktons were selected because they are safe and healthy for your aquatic ecosystem, excellent food for zooplankton and have high consumption rates of phosphate including the ability to utilize luxury uptake which impedes the development of toxic algae and other nuisance algae. Phosphate is the primary fertilizer to facilitate a toxic algae bloom (cyanobacteria). With beneficial phytoplankton, you can fight bad algae by utilizing good algae instead of algaecides or chemicals.
Our Fastest-Dividing Species
Phosphorus Removal
Phosphorus, often the limiting nutrient in freshwater ecosystems, is a strong target for this species' efficient uptake mechanisms. This species absorbs phosphorus primarily as orthophosphate (PO₄³⁻), incorporating it into cellular components including nucleic acids, phospholipids, and ATP.
Our fastest-dividing species can remove phosphorus at rates of 1-10 mg per gram of biomass per day, depending on initial phosphorus concentrations and growth conditions. Studies have documented removal efficiencies of 70-90% of total phosphorus from wastewater and agricultural runoff within several days of exposure to cultures of this species.
Our fastest-dividing species also has the ability to consume and store more phosphate than it needs to grow through polyphosphate chains. This ability is commonly referred to as luxury uptake.

Our Most Adaptable Species
Phosphorus Removal Rates: This species can remove 80-95% of available phosphorus from water under optimal conditions, with uptake rates typically ranging from 5-15 mg/L/day. The algae stores phosphorus as polyphosphate granules, which can constitute up to 3-4% of its dry weight.
Luxury Uptake: This species exhibits "luxury uptake" of phosphorus, meaning it can absorb and store more phosphorus than immediately needed for growth. This characteristic enhances its effectiveness as a bioremediator, as it continues removing phosphorus even when cellular requirements are met.
Our Highest-Value Forage Species
Phosphorus Consumption
Phosphorus is essential to the growth of this species, needed for DNA, RNA, ATP, and phospholipid synthesis. The alga demonstrates efficient phosphorus uptake:
Orthophosphate (PO₄³⁻): This species can remove 1-5 mg/L of phosphate-phosphorus per day under optimal growth conditions. At low phosphorus concentrations, the algae exhibits luxury uptake, storing excess phosphorus as polyphosphate granules for future use.
Nitrogen-to-Phosphorus Ratios: This species typically maintains cellular N:P ratios between 10:1 and 20:1 by mass, though this can vary with environmental conditions. This means that for every gram of phosphorus removed, the alga simultaneously removes approximately 10-20 grams of nitrogen.
Our Highest Phosphate-Uptake Species
Phosphorus Uptake
Phosphorus uptake rates typically range from 0.1 to 1 mg PO₄³⁻-P per gram of algae per hour under nutrient-sufficient conditions. During exponential growth, phosphorus can comprise 1-3% of the algae's dry weight. Importantly, this species can also store excess phosphorus in polyphosphate granules, a process called "luxury uptake," allowing it to remove phosphorus beyond its immediate growth requirements.
This phosphorus removal capability is particularly valuable because excess phosphorus is a primary driver of eutrophication and harmful algal blooms in freshwater bodies. By effectively sequestering phosphorus, this species helps maintain balanced aquatic ecosystems.
Our Highest Omega-3 Species
Phosphorus Uptake
Uptake Rates: Related species typically demonstrate phosphorus uptake rates of 0.01-0.03 grams per gram of biomass per day. While this may seem modest compared to nitrogen, it's important to remember that phosphorus requirements for algae growth are significantly lower, with typical N:P ratios around 16:1 (the Redfield ratio).
Luxury Uptake: This species can engage in luxury consumption of phosphorus, storing excess phosphate in cellular compartments as polyphosphate granules when concentrations are high. This stored phosphorus can then support growth during periods of phosphorus limitation.
Our Most Digestible Species
Phosphorus Removal
Phosphorus is the critical nutrient that this species removes from water efficiently. This is important because phosphorus is the limiting nutrient to toxic algae blooms and nuisance algae. Therefore, when phosphorous is utilized by a good algae instead of a toxic cyanobacteria we can essentially feed zooplankton while inhibiting the development of harmful algae blooms. These phytoplankton require phosphorus for energy metabolism, DNA synthesis, and cell membrane structure. This species typically contains 0.5% to 1% phosphorus by dry weight and can achieve phosphorus removal rates of 0.01 to 0.05 mg per billion cells per hour under favorable conditions.
The algae's ability to store excess phosphorus as polyphosphate granules allows them to remove more phosphorus than immediately needed, providing a buffer against future scarcity and enhancing their water purification capacity.
