What is Lake Therapy by Oase?
Lake Therapy is a professional, environmentally sustainable treatment system by the German brand Oase, designed to restore natural balance in lakes, ponds, and large bodies of water.
Using specially developed biological and mineral-based products, this therapy digests organic sludge, binds excess phosphorus, balances the pH, and improves oxygen levels — without invasive dredging or the use of chemicals.

-
What is Oase Lake Therapy?Oase Lake Therapy is a professional, eco-friendly treatment system that uses biological and mineral-based products to naturally restore lakes and ponds by reducing sludge, binding excess phosphorus, and improving water clarity and health.
-
Is Lake Therapy safe for fish, birds, and other wildlife?Yes. All Oase products are designed to be completely safe for aquatic life, pets, and surrounding wildlife. No harmful chemicals are used.
-
Can Lake Therapy replace dredging?In many cases, yes. Products like SchlixX Plus can significantly reduce or eliminate the need for costly and disruptive dredging by breaking down organic sludge biologically.
-
How long does it take to see results?Most ponds and lakes begin showing improvement within 2–6 weeks of treatment. Full restoration depends on water conditions, but major gains are often seen over one season.
-
How much does Oase Lake Therapy cost?Costs vary depending on the size of your lake and the severity of the problem. We offer a free site visit and water analysis to create a tailored quote.
-
How often does the treatment need to be repeated?This depends on the condition of your water body. Some treatments are annual (like OptiLake), while others may be needed more regularly at the start, then maintained seasonally.
-
What causes sludge and algae in lakes and ponds?Sludge builds up from organic matter like leaves, fish waste, and runoff. Algae blooms are typically caused by excess nutrients, especially phosphorus. Oase products target these root causes.
-
Is Lake Therapy suitable for large lakes or reservoirs?Yes. The treatment is scalable for small garden ponds to large estate lakes, golf course water features, and even farm reservoirs.
-
Can I swim in the lake after treatment?Yes, once the product has been applied and settled (usually 24–48 hours), the water is safe for recreational use including swimming and fishing.
-
Do you offer ongoing maintenance or support?Absolutely. FishLife provides seasonal service plans to monitor water health, reapply treatments when needed, and keep your lake in peak condition year-round.
