Oase Sedox Max Lake Therapy Water Treatment

Oase SeDox Max Lake Therapy Water Treatment

Advanced Phosphate Binding and Nutrient Locking for Persistent Algae and Blanketweed

Oase SeDox Max is a high capacity phosphate removal treatment developed for lakes, ponds, reservoirs, fisheries, and restoration projects suffering from long term nutrient enrichment. In established systems, even moderate phosphate concentrations can sustain algae blooms, fuel blanketweed growth, reduce water clarity, and destabilise ecological balance.

Phosphate typically enters a water body through fish waste, uneaten feed, decomposing organic matter, fertiliser run off, sediment release, and natural nutrient cycling. Once concentrations rise above 0.035 milligrams per litre, algae and filamentous blanketweed can multiply rapidly. In many mature lakes, phosphate is not only present in the water column but is also continuously released from deep sludge layers.

SeDox Max has been engineered to control both sources. It works as an advanced phosphate binding product that captures dissolved orthophosphate in the water column while also locking nutrients released from sediment. As soon as the treatment is applied, binding begins within hours. At the same time, its multi component mineral formulation continues immobilising phosphate over an extended period, delivering reliable long term nutrient control.

Unlike short term reactive algae treatments, SeDox Max tackles the root cause of recurring blooms. It converts free phosphate into a stable insoluble mineral form that algae and blanketweed cannot absorb. Because this conversion occurs at both sediment level and throughout the water column, nutrient pressure is reduced comprehensively rather than temporarily masked.

With a high binding capacity of 30 grams of phosphorus per kilogram of product, SeDox Max performs effectively even in heavily loaded systems. This makes it particularly suitable for large lakes, commercial fisheries, golf course water bodies, estate lakes, and restoration schemes where sustained phosphate reduction is essential.

As phosphate availability decreases, algae reproduction slows and blanketweed weakens. Consequently, water clarity improves, oxygen levels stabilise, and organic sludge accumulation reduces. Over time, this creates a healthier and more resilient aquatic environment for fish, plants, and beneficial micro organisms.

SeDox Max is environmentally safe, mineral based, and easy to apply. It delivers fast initial results while supporting several months of continued phosphate immobilisation, making it one of the most powerful nutrient management tools within the Oase Lake Therapy range.

Dosage and Coverage

Oase SeDox Max is dosed by water volume.

• 5 kg treats up to 100,000 litres
• 10 kg treats up to 200,000 litres
• 25 kg treats up to 500,000 litres

Selecting the correct pack size ensures effective phosphate binding without overdosing and allows the treatment to perform at optimum efficiency.

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.
