SeDox Max – Find out more about this revolutionary product in this follow-up after the webinar
In our latest Maxed Out webinar, we explored how nutrients drive water quality issues and discussed how SeDox Max is revolutionizing the industry. While we covered many of your questions during and after the session, our experts have compiled this follow-up to address the most frequently asked questions.
Dosing & Cost
Q: What are the recommended use rates and application methods? How do we calculate dosage from TP/SRP and sediment P levels?
A: SeDox Max is dosed based on Total Phosphorus (TP), since all of it eventually cycles into Soluble Reactive Phosphorus (SRP). The best time to apply is when SRP makes up the highest percentage of TP—typically in early spring, post-biocide treatments, or late season. Costs vary by site and phosphorus load, but it’s most accurate to calculate cost per pound of phosphorus removed.
Product Comparisons
Q: How do Oase solutions like SeDox Max compare with lanthanum-based products in performance, longevity, safety, and cost?
A: SeDox Max blends lanthanum with the original SeDox formulation, giving it two permanent binding mechanisms: forming hydroxyapatite and rhabdophane. With a capacity of 1.5 lbs (450 g) of phosphorus per 50 lb bag (30g P/kg), it outperforms most lanthanum-only products. Phosphorus is locked in a mineral form, permanently removing it from the cycle.
Unlike many alternatives, all components in SeDox Max are active—delivering alkalinity, oxygen release, microbial support, and overall water quality improvements. There are no inert fillers.
Scaling & Implementation
Q: How should operators managing multiple lakes integrate these products into their plans?
A: There are two common approaches:
1. Pond Reset: Apply the full required dose in one treatment to immediately bind available phosphorus.
2. Seasonal Maintenance: Divide the dose into smaller applications throughout the year to gradually reduce nutrient loads.

Effectiveness, Ingredients & Longevity
Q: How effective are Oase Lake Therapy products, how do they work, and how long do results last?
A: Oase lake therapy products: SeDox, SeDox Max, SchlixX, and SchlixX Plus are mineral-based solutions that bind nutrients, boost oxygen, and accelerate sediment cleanup.
Active Ingredients: All products use calcium peroxide, which releases oxygen for up to 8 weeks and is able to bind SRP in the insoluble mineral hydroxyapatite. SeDox Max adds lanthanum to enhance phosphate binding, forming the stable mineral rhabdophane. SchlixX Plus also contains eight strains of beneficial bacteria to speed up organic matter breakdown.
How They Work: Oxygen release stimulates aerobic bacteria in sediments, binds phosphorus, breaks down hydrogen sulfide (reducing odors), and improves water clarity by degrading organics.
Real-World Results:
Immediate increase in dissolved oxygen
• Up to 99% reduction in phosphate and >85% reduction in total phosphorus (TP)
• Average 15% sediment organic matter reduction (up to 35%)
• Sediment depth declines 15 cm, or 6 in, per dose (up to 79 cm, or 31 in)
Longevity: Results typically last several years, depending on external nutrient inputs; with proactive maintenance dosing, benefits can extend up to 8 years
Best Practices to Reduce Muck, Control Nutrients, and Maintain Lake Health (Including Timing)
Q: What are the best practices to reduce muck, control nutrients, and maintain overall lake health—including optimal timing of treatments?
A: Mechanical dredging often increases turbidity, disturbs seedbanks, and exposes nutrient-rich sediments—while also being costly. Oase products achieve the same goals more effectively and with fewer drawbacks:
Product Selection:
• SchlixX Plus - Breaks down organic matter and binds phosphorus released in the process.
• SeDox and SeDox Max - controls nutrients in the water column and from sediments, while adding inorganic carbon to balance C:N:P ratios, reduce excess phosphorus, and aid nitrification.
Timing: For recurring spring/summer algal blooms (often sediment-driven), apply SeDox Max in fall through early spring—when phosphorus is mostly concentrated at the sediment layer—to prevent release before the growing season.
