The Oase OptiMax is a compact, quiet, energy-efficient water pump for circulation and powering aquarium equipment — driving canister returns, sumps, reactors, or simply adding flow. German-engineered for reliability, it runs quietly with adjustable flow control built in, so you can tune output to your setup. Multiple sizes (85i through 560) cover everything from nano circulation to larger systems.
Good to Know: Good water movement is important in a planted tank — it distributes CO₂ and nutrients evenly and prevents stagnant "dead spots" where detritus and algae accumulate. The adjustable flow lets you match the current to your livestock (gentler for nano fish and shrimp, stronger for flow-loving species). The "i" models are designed for fully-submerged in-tank use.
How to Use: Choose the size for your application and tank volume, position it for good circulation, and set the flow. Keep the intake clear and rinse the impeller periodically for quiet, reliable running.
