Oase PeriDox Lake Therapy Water Treatment
Comprehensive Parasite Control and Oxygen Enrichment
Oase PeriDox is a fast acting treatment developed for fish stocked ponds and lakes that require reliable parasite control alongside rapid oxygen enrichment. During warm periods and under high stocking densities, parasite pressure can increase quickly. As a result, fish may suffer from gill irritation, excess mucus production, reduced oxygen uptake and weakened immune response. In severe cases, untreated outbreaks can lead to widespread fish losses.
PeriDox provides an immediate and effective response while supporting overall water stability. As soon as the product is applied, an oxidation process begins. This process destroys the cell structure of parasites and their larvae on contact. Under normal conditions, parasite larvae can survive in water for 33 to 48 hours. However, when the correct PeriDox dosage is used, larvae are eliminated within approximately 3 hours.
Because adult parasites continue releasing new larvae, a single treatment is not sufficient to break the lifecycle. Therefore, PeriDox should be applied 3 to 4 times at the recommended interval to fully reduce parasite pressure and prevent reinfestation.
In addition to parasite control, PeriDox delivers immediate oxygen enrichment. During oxidation, oxygen is released directly into the water column. Consequently, dissolved oxygen levels rise rapidly. This makes PeriDox particularly valuable during warm weather, high organic loading, or when fish show signs of oxygen stress such as gasping at the surface.
Furthermore, PeriDox supports carbonate hardness, helping maintain more stable water chemistry during treatment. Stable parameters are essential when fish are already stressed, as sudden changes can worsen health issues and delay recovery.
PeriDox is classified as a non prescription biocide and leaves no harmful residues once the oxidation reaction is complete. When used correctly, it does not endanger fish or disrupt the wider ecosystem. However, it must only be used in isolated and self contained water bodies to ensure treatment remains controlled and effective.
PeriDox is particularly suited to fisheries, commercial ponds, heavily stocked lakes and managed aquatic systems where both parasite control and oxygen stability are critical.

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.
