Vertex Omega 180i Protein Skimmer fit check
Vertex Omega 180i Protein Skimmer is an in-sump internal protein skimmer rated up to 184 gallons. Box ratings assume light stocking, so ReefCrafter scales them by bioload: about 125 gallons lightly stocked, 90 gallons medium, or 75 gallons for a heavily fed fish tank.
Vertex Omega 180i Protein Skimmer: fits roughly 90-184 gallon systems. Specs, compatibility math, sizing risks, and alternatives before you buy.

Compatibility math
Bioload headroom
Example: On a 75g mixed reef, ReefCrafter wants about 150g of skimmer rating for medium bioload.
Vertex Omega 180i Protein Skimmer is rated around 184g, so the useful question is whether that clears the fish load with margin.
Risk notes
- A skimmer can be fine for a light reef and thin for the same tank once feeding and fish load increase.
- Price is marked as estimated, so verify current vendor pricing before treating the budget as final.
Professional fit context
- Compare rated maximum gallons, physical fit, cup clearance, noise, and bioload margin.
- Vertex Omega 180i Protein Skimmer fits roughly 90-184 gallon systems; confirm that range against the final display volume, sump volume, and livestock plan.
- Treat the displayed price as a budget placeholder until a reviewed vendor page confirms current pricing.
