O-Zone

[MichaelReefer]

Good evening. I am thinking about running Ozone however my RSK300 isnt O-Zone rated. I know some people use a small skimmer that is Ozone rated to run it. How small can you go? Like would a tiny hang on the back work? Or do you need substantial size?

Yes—you can use a smaller ozone-rated skimmer, even something like a compact hang-on-back (HOB) model. However, its effectiveness will depend on a few key factors:
Key considerations:

1. Contact Time & Reaction Volume​

• Ozone needs adequate contact time with water to oxidize organics effectively. This usually happens in the skimmer body.
• A tiny skimmer might not provide enough dwell time unless it's specifically designed to handle ozone safely and efficiently.
• You might also lose a lot of ozone as gas quickly if the body is too small and not sealed well.

2. Ozone Injection Control​

• You'll want very precise control over how much ozone is being injected—generally no more than 5–15 mg/hr per 50 gallons of water.
• With a smaller skimmer, stay on the lower end of ozone dosing to avoid over-oxidation or excess ozone leaking into the room.

3. Air Handling & Off-Gassing​

• Small skimmers often don't handle ozone off-gassing well.
• You'll need to run the skimmer air output through carbon (like a carbon sock or air dryer tower) to neutralize excess ozone.
• Similarly, skimmer cup overflow or reactor exhaust must pass through carbon to avoid ozone release into your home. If you're looking for a compact, ozone-safe skimmer, consider these:
  
  • Reef Octopus Classic 100-HOB – HOB, solid construction, ozone-safe.
  • Deltec MCE600 – Excellent build, ozone-compatible, quiet and efficient.
  • AquaMaxx HOB 1.5 or HOB-S – Some models are ozone-resistant (confirm materials).
  • Nyos Quantum 120 – If you want something small-footprint and sump-ready.

Thank you for your response!

Would something small like this work?

Why yes most likely. It is ozone rated!

Trying to find something comapact I can fit in the sump.
