How do I choose the right size aquarium filter for my tank?

Match the filter's rated flow (LPH or GPH) to your tank volume. A common guideline is a filter that cycles the full tank volume roughly 4 or more times per hour. For a heavily stocked tank, choose a filter rated for a slightly larger volume to keep water clear. The OASE CrystalSkim 600 is suitable for tanks up to 160 gallons (600 L).

What is the difference between mechanical, biological, and chemical filtration in these units?

Mechanical filtration traps debris using sponges or floss, biological filtration hosts beneficial bacteria on bio-media to break down waste, and chemical filtration uses activated carbon to remove discoloration and odours. The OASE CrystalSkim 600 primarily focuses on mechanical surface filtration to remove film and debris.

Is the OASE CrystalSkim 600 safe for small fish and shrimp?

Yes, the OASE CrystalSkim 600 features a removable collection basket with fine intake slots designed to protect delicate livestock like shrimp and small fish while effectively capturing surface particles.

How does the OASE CrystalSkim 600 improve water circulation?

In addition to surface skimming, the CrystalSkim 600 has a built-in bottom outlet that creates gentle flow in low-circulation zones where debris tends to collect. This helps reduce dead spots and supports overall tank health.

What is the flow rate of the OASE CrystalSkim 600?
