Oase Algoshield Lake Therapy Water Treatment

Oase AlgoShield Lake Therapy Water Treatment

Effective Algae Control Without Chemicals

Oase AlgoShield is an advanced, chemical free algae control treatment developed for lakes, ponds, reservoirs and natural biotopes where environmental sensitivity and long term stability are essential. Excessive algae growth usually signals biological imbalance. Elevated nutrient levels from fertiliser run off, plant decay, fish waste or poor circulation allow algae to multiply rapidly. As a result, water clarity declines, oxygen levels fluctuate and pH can become unstable.

In severe cases, blue green algae may develop and release toxins that threaten fish, wildlife and recreational users. Therefore, preventing algae growth before blooms form is critical in high value or sensitive water bodies.

How AlgoShield Controls Algae Naturally

AlgoShield provides a modern alternative to traditional algae treatments. Rather than using biocides, heavy metals or oxidising agents, it relies on innovative SpectroSorb technology. SpectroSorb particles selectively block specific ultraviolet wavelengths required for algal photosynthesis. Without access to this light spectrum, algae cannot grow or reproduce efficiently.

Because AlgoShield prevents photosynthesis rather than killing algae aggressively, it avoids sudden die off events that can destabilise water chemistry. Consequently, water clarity improves gradually and biological balance recovers naturally.

AlgoShield is effective against both green algae and blue green algae. Green algae typically cause cloudy or discoloured water. In contrast, blue green algae can produce harmful toxins and create serious risks in lakes and natural swimming areas. By limiting photosynthesis at the source, AlgoShield reduces the likelihood of dangerous blooms developing.

In addition, reducing excessive algae growth helps stabilise carbonate hardness and prevent sudden pH swings. Stable pH and kH values are essential for fish health, plant growth and long term clarity. Therefore, AlgoShield is particularly well suited to sensitive ecosystems and conservation waters.

AlgoShield works gently and continuously throughout the growing season. It is safe for fish, aquatic plants, wildlife and natural swimming environments when used correctly. Because it contains no harsh chemicals, it supports ecological balance rather than disrupting it.

For best results, use AlgoShield as part of a structured lake management strategy. While AlgoShield limits algae growth through light control, underlying nutrients such as phosphate should also be managed where necessary using phosphate binding treatments.

Oase Lake Therapy Range Overview

The Oase Lake Therapy range is designed to work as a complete, long term water management system rather than a collection of standalone treatments. Each product targets a specific underlying issue, and when used together, they help maintain clear, balanced, and healthy ponds and lakes throughout the year.

OptiLake
Forms the foundation of long term water management by stabilising pH and carbonate hardness. OptiLake creates ideal conditions for fish health, plant growth, and beneficial micro organisms, and is widely regarded as one of the most important products in the range for ongoing water stability.

Clearlake
A natural biological water treatment designed to clear cloudy water, reduce organic sludge and restore ecological balance in ponds and lakes. It strengthens beneficial bacteria, improves filtration efficiency and supports long term water clarity.

SchlixX
Targets organic sludge at the sediment layer by releasing oxygen and activating natural micro organisms. SchlixX reduces internal nutrient release, improves water clarity, and significantly reduces the need for mechanical dredging.

SchlixX Plus
An advanced sludge reduction treatment containing specially cultivated aquatic micro organisms. SchlixX Plus accelerates sludge digestion, binds released phosphate, and delivers long lasting sediment improvement, making it ideal for heavily impacted lakes and ponds.

SchlixX OxySpeed
Provides rapid oxygen enrichment across large surface areas while also supporting sludge stabilisation at the sediment level. Ideal for emergency oxygen depletion events, summer stress periods, and proactive lake restoration.

SeDox
A long term phosphate binding treatment that removes the primary nutrient responsible for algae and blanketweed growth. SeDox helps maintain clear water and prevents recurring algae problems by addressing nutrient levels at their source.

SeDox Speed
A fast acting phosphate binder designed for rapid response situations. SeDox Speed delivers immediate phosphate reduction within hours and is ideal for sudden nutrient spikes or active algae and blanketweed outbreaks.

SeDox Max
A highly concentrated phosphate treatment engineered for persistent nutrient overload and sediment related phosphate release. SeDox Max provides both rapid and long lasting phosphate immobilisation, supporting long term lake restoration projects.

AlgoLon
A fast acting blanketweed and thread algae treatment that uses active oxygen to break down filamentous algae within hours. For best long term results, AlgoLon should always be followed by phosphate control using SeDox or SeDox Speed.

AlgoShield
A chemical free algae prevention treatment that blocks photosynthesis using SpectroSorb technology. AlgoShield is ideal for sensitive environments and long term algae control without biocides or heavy metals.

CyanoClear
An emergency treatment designed to remove blue green algae and neutralise cyanobacteria toxins within 48 hours. CyanoClear is used when water safety is critical and should be followed by nutrient management to prevent recurrence.

PeriDox
A fast acting parasite control and oxygen enrichment treatment for fish stocked ponds and lakes. PeriDox reduces parasite pressure while rapidly increasing dissolved oxygen during high risk periods.
