AquaMaxx ConeS CO-1 In-Sump Protein Skimmer fit check
AquaMaxx ConeS CO-1 In-Sump Protein Skimmer is an in-sump cone protein skimmer rated up to 90 gallons. Box ratings assume light stocking, so ReefCrafter scales them by bioload: about 60 gallons lightly stocked, 45 gallons medium, or 35 gallons for a heavily fed fish tank.
AquaMaxx ConeS CO-1 In-Sump Protein Skimmer: fits roughly 50-175 gallon systems. Specs, compatibility math, sizing risks, and alternatives before you buy.
Who it is for
Good fit for
- ✓ 50-175 gallon systems, per the catalog fit range.
- ✓ Heavily fed tanks up to about 35 gallons, or lightly stocked tanks up to about 60 gallons.
Not a fit for
- ✕ Tanks under about 50 gallons; it is sized above them.
- ✕ Systems over about 175 gallons without adding capacity elsewhere.
- ✕ Heavy-bioload tanks above about 35 gallons; the box rating assumes light stocking.
- ✕ Hang-on-back or AIO setups without a sump chamber deep enough for it.
Compatibility math
Bioload headroom
Example: On a 75g mixed reef, ReefCrafter wants about 150g of skimmer rating for medium bioload.
AquaMaxx ConeS CO-1 In-Sump Protein Skimmer is rated around 90g, 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.
- AquaMaxx ConeS CO-1 In-Sump Protein Skimmer fits roughly 50-175 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.
