Project overview
A science-led nutrient management strategy
As part of its Town Center development, the City of Early, Texas set out to transform a former agricultural pond into a 7-acre recreational fishing lake designed to serve as a long-term community asset.
Shortly after construction and refill, the lake experienced significant water quality challenges driven by elevated nutrient levels and rapid algae growth.
Oase Water Technology, working alongside Texas Pro Lake Management, was engaged to design and deliver a science-led nutrient management strategy focused on long-term system stability.
We wanted to do something different than just build another park. We envisioned turning this into a fishing lake that could really become the heart of the community.

The challenge
Although the lake itself was newly constructed, it was filled using existing river water. This introduced high nutrient loads into a system without an established biological foundation, creating ideal conditions for algae growth.
Key challenges included:
Elevated phosphorus concentrations
Imbalanced nitrogen dynamics
Rapid algae development and poor water clarity
Limited microbial activity in newly formed sediments
A requirement for solutions safe for public use
We brought old water into a new pond. That meant high nutrients, but without the sediment bacteria needed to process them. And we needed something that could actually control the phosphorus. That was the missing piece.
– Steven Bardin, Texas Pro Lake Management
Early stabilization measures such as aeration and sonic control helped, but phosphorus remained the critical limiting factor.
The solution
Following water sampling and nutrient analysis, Oase and Texas Pro Lake Management implemented a targeted nutrient management approach designed to address root causes rather than suppress symptoms.
At the centre of the solution was SeDox Max, a calcium peroxide-based treatment engineered to:
Permanently bind bioavailable phosphorus
Release oxygen during activation rather than depleting it
Support beneficial microbial processes
Improve nitrogen cycling and overall system stability
SeDox Max was applied using a controlled, boat-based method to ensure even distribution across the lake, alongside beneficial bacteria to support biological balance.
Importantly, application was non-disruptive, allowing normal recreational use of the lake to continue.
With most of the issue being in the water column, we were able to treat the lake with SeDox Max to bind the phosphorus and support nitrogen balance.

The results
Results were rapid, visible and sustained.
One of the first things we noticed was the water becoming visibly clearer during application.
– Steven Bardin, Texas Pro Lake Management
During application, water clarity improved immediately, with filamentous algae visibly declining. In the weeks that followed, the lake transitioned from eutrophic conditions to a clear, stable system aligned with regional expectations.
Instead of green soup, you could start to see down into the water again. It looked natural.
– Tony Aaron, City Administrator, City of Early
Key outcomes included:
Significant reduction in phosphorus availability
Rapid improvement in water clarity
Suppression of nuisance algae growth
Improved oxygen conditions
Stabilized nutrient dynamics
These improvements have been maintained into subsequent seasons, demonstrating long-term effectiveness.
Community impact
The restored lake now functions as a central feature of the City of Early’s Town Center, supporting recreational fishing, walking, and everyday community use.
From a municipal perspective, improved water quality has increased the usability, perception, and long-term value of the site, supporting broader development and placemaking goals.
Instead of just having a body of water, we now have a pristine opportunity for people to enjoy, fish, and spend time together.
– Tony Aaron, City Administrator, City of Early
Product validation
This project provides strong third-party validation for SeDox Max as a solution for new or renovated water bodies where nutrient imbalance and biological immaturity present high risk.
Validated performance outcomes include:
Effective phosphorus control in a high-load system
Visible improvement during application
Safe use in publicly accessible environments
Compatibility with aeration and biological strategies
Long-term stabilization rather than short-term algae suppression.
Ongoing partnership
The City of Early continues to work with Oase Water Technology and Texas Pro Lake Management as part of a preventative, long-term water quality strategy, ensuring the lake remains a sustainable community asset.
The City of Early has been one of those partners you dream of. They’re doing something for their community we wish we could replicate across the state.
