Reliable. The Fog Fluid That Handles Everything. Nebula™ Core is the all-purpose fog fluid in the SurgeFX lineup — a clean, balanced formula that delivers consistent, professional-quality fog for any standard application. Medium hang time, dense white output, universal machine compatibility, and the lowest price point in the Nebula line. If you need fog and you're not sure which formula to buy, this is the one. Core doesn't specialize in any one behavior. It doesn't dissipate as fast as Mirage, doesn't hang as long as Eternal, doesn't resist wind like Endure, and doesn't hug the ground like Liquid Gravity. What it does is handle everything well — the versatile workhorse that covers the vast majority of fog applications without compromise. Water-based, residue-free, ready to use. Compatible with all standard heated fog machines from 700W to 3000W. Made in the USA. 1 gallon (3.78 liters). 🌫️ Overview 🔄 Fog Fluid Comparison ❓ FAQ 💡 Tips The All-Purpose Standard Most fog applications don't need a specialty formula. They need good fog that works reliably — dense enough to see, persistent enough to build atmosphere, clean enough to leave no residue, and compatible with whatever machine you own. That's Core. Nebula™ Core produces thick white fog with medium hang time — long enough to create atmosphere and enhance lighting, short enough that it doesn't overwhelm the space or require active management. It's the balanced center point of the Nebula line, and it's the formula most operators will use for most shows. The specialty formulas exist for specific problems: when you need fog that clears faster, hangs longer, fights wind, or stays on the ground. Core exists for everything else — which is the vast majority of fog applications. And at the lowest price in the line, there's no premium for versatility. Feature Nebula™ Core Size 1 Gallon (3.78 Liters) Fluid Type Water-based, all-purpose fog Hang Time Medium — balanced persistence Output Character Dense, clean, consistent white fog Residue None Scent Neutral Machine Compatibility All standard heated fog machines (700W–3000W) Made In USA Applications DJ & Club Performances — Reliable atmosphere that enhances lighting without overwhelming the room or requiring constant management. Stage Productions & Theater — General-purpose fog for scenes, transitions, and atmospheric effects that don't need specialty timing. Haunted Attractions & Halloween Events — Room-filling fog for indoor haunts, escape rooms, and themed environments. Laser Shows & Lighting Enhancement — Medium-hang fog that makes beams visible and maintains density across a performance. Wedding Entrances & Event Effects — Clean, dramatic fog for grand entrances, first dances (rising fog), and reception atmosphere. Film & Video Production — Consistent, controllable atmosphere for studio and location shoots. School Events, Dances & Proms — Safe, residue-free fog that works with any machine and cleans up with zero effort. The Core Advantage: Most operators don't need the most specialized fog — they need the most reliable fog. Core delivers professional results across every standard application, works in any machine, and costs less than the specialty formulas. When in doubt, start here. Nebula™ Fog Fluid Line — Which Formula Do You Need? SurgeFX offers five fog fluid formulas. Core is the center of the lineup — the balanced all-purpose fluid that handles the widest range of applications. The specialty formulas exist for situations where standard performance isn't enough. Formula Hang Time Best For Price Nebula™ Mirage Short — clears fast Timed cues, laser bursts, dance reveals $33.99 Nebula™ Core ← This Product Medium — balanced General use, all-purpose $27.99 Nebula™ Eternal Long — lingers Sustained scenes, immersive environments $33.99 Nebula™ Endure Long — wind-resistant Outdoor events, open-air stages $33.99 Nebula™ Liquid Gravity Ground-level only Weddings, theater, haunts (requires chiller) $38.00 Do You Actually Need a Specialty Formula? The specialty formulas solve specific problems. If you don't have those specific problems, Core is the right answer — and the most affordable one. Here's a quick decision guide: Your Situation Use Core? Or Switch To... General indoor fog for a club, stage, haunt, or event ✓ Yes — Core handles this — Fog needs to clear in seconds for tight cues Core is too slow Mirage Fog must stay for hours without constant refiring Core fades too fast Eternal Outdoor event with wind and open air Core scatters in wind Endure Fog that hugs the floor (walking on clouds) Core rises — wrong effect Liquid Gravity Not sure / first time buying fog fluid ✓ Start with Core — Bottom Line: Core covers about 80% of fog applications. The specialty formulas exist for the other 20% — specific situations where timing, persistence, wind resistance, or ground-level effects matter enough to justify the price difference. If you're not sure, Core is the right starting point. You can always add specialty fluids later for specific needs. Frequently Asked Questions Q: What machines does Core work with? Any standard heated fog machine from 700W to 3000W. Fully universal — compatible with Chauvet, ADJ, Antari, and all other major brands. If your machine uses standard fog fluid, Core runs in it. No special equipment or adapters required. Q: How long does the fog last? Medium hang time — long enough to create visible atmosphere and enhance lighting, short enough that it naturally clears without requiring active ventilation. In a typical indoor space, you'll get several minutes of visible fog from a burst, with gentle dissipation rather than sudden disappearance. Exact duration depends on room size, temperature, humidity, and air movement. For significantly longer persistence, consider Eternal. For significantly faster clearing, consider Mirage. Q: Is Core good enough for professional use? Yes. Core is a professional-grade fog fluid — it's the same quality as the specialty formulas, just with balanced rather than specialized behavior. Professional DJs, production companies, haunted attractions, and theater operators use Core as their primary fog fluid. The specialty formulas aren't "better" — they're optimized for narrower use cases. Core is optimized for the widest possible range of applications. Q: Will it trigger smoke detectors? Any fog fluid can trigger smoke detectors. Core's medium hang time puts it in the middle of the risk spectrum — less likely to trigger detectors than long-lasting Eternal (which accumulates near ceiling sensors), more likely than quick-dissipating Mirage (which clears before reaching ceiling level). Always coordinate with venue management before any fog use, and be aware of detector placement in your space. Q: Can I use Core outdoors? It works outdoors in calm conditions, but it's not designed for it. Even a light breeze will dissipate Core quickly in open air. If outdoor fog is your primary use case, Nebula™ Endure is specifically formulated for wind resistance. Core is best suited for indoor environments or very sheltered outdoor spaces. Q: Will Core make fog that stays on the ground? No. Core produces standard rising fog that fills the room. For ground-hugging, low-lying fog (the "walking on clouds" effect), you need Nebula™ Liquid Gravity paired with a low-lying fog machine or fog chiller. Core in a standard fog machine will always produce fog that rises. Q: Can I mix Core with other Nebula fluids? We don't recommend mixing fluids in the same tank. Each formula is calibrated for specific behavior, and mixing changes the characteristics unpredictably. If you want different fog behaviors during the same event, run separate machines loaded with different fluids. Q: What's the difference between fog and haze? Fog produces thick, visible clouds you can see. Haze produces a nearly invisible atmospheric layer that makes light beams visible without creating visible clouds. Core is fog. If you want haze for subtle beam enhancement, check the Aurà™ haze fluid line. Q: Is it safe? Yes. Water-based, non-toxic, residue-free, neutral scent. Safe for performers, audiences, equipment, and venues. No oil, no glycol residue on surfaces. Suitable for all ages and environments, including schools and family events. Getting the Most From Core 🎯 Start with Core, specialize later. If you're new to fog effects or building out your fluid inventory, Core is the right first purchase. It handles the majority of applications well, and you'll learn what your specific shows actually need. Once you identify situations where Core's behavior isn't quite right — fog lingers too long for your cues, or dissipates too fast for your haunt — that tells you exactly which specialty formula to add. Most operators end up keeping Core as their primary fluid and adding one or two specialty formulas for specific use cases. 🎯 Match your machine output to the room. Core's medium hang time means your machine wattage and output setting determine how much fog stays in the space at any given time. In a small club or escape room, a 700W machine on moderate output builds atmosphere quickly. In a large theater or arena, you'll need higher-wattage machines or multiple machines to create visible density across the full space. Let the room size guide your hardware decision — Core's formulation handles the rest. 🎯 Use lighting to amplify the effect. Fog without light is just fog. Fog with proper lighting is an effect. Colored beams cut through Core beautifully, lasers pop against the medium-density background, and moving lights create dynamic patterns through the fog. Plan your lighting around your fog — even moderate fog density looks spectacular when well-lit. 🎯 Manage airflow for your desired effect. Core's medium hang time makes it responsive to ventilation. Want fog to linger longer? Reduce air movement — close doors, lower HVAC during fogged scenes. Want fog to clear faster? Open a door or increase airflow. Core gives you a natural middle ground that you can push in either direction by managing the room environment. 🎯 Fog in bursts, not continuous. For most indoor applications, periodic bursts with pauses between them produce the best results with Core. Fire a burst to build the atmosphere, let the fog distribute, then fire again when density drops below your desired level. Continuous output tends to over-fog the room and waste fluid. The exception is large-volume spaces where you need sustained output to build density in the first place. 🎯 Keep your machine clean. Core is residue-free and gentle on fog machine heat exchangers, but regular maintenance still matters. Flush your machine after extended use, clean the tank periodically, and follow the manufacturer's maintenance schedule. A well-maintained machine produces better fog output and lasts longer regardless of which fluid you run. 🎯 Know when Core isn't enough. Core is the right answer for most situations, but recognizing its limits will make you a better operator. If you're constantly fighting fog that hangs too long for theatrical cues — that's a Mirage problem. If you're refiring every few minutes to maintain haunt atmosphere — that's an Eternal problem. If wind is destroying your outdoor fog — that's an Endure problem. Core tells you when to upgrade by showing you where it falls short.

Safe for all ages, including school events and family environments. 💡 Tips Getting the Most From Core 🎯 Start with Core, specialize later. Learn what your shows actually need. When Core falls short in specific ways — too slow to clear, too fast to hold — that tells you exactly which specialty formula to add. Most operators keep Core as primary and add one or two specialty fluids. 🎯 Match machine to room. Core's medium hang time means output determines density. Small room = 700W works great. Large venue = go higher wattage or multiple machines. Let room size guide hardware; Core handles the rest. 🎯 Light the fog. Fog without light is just fog. Colored beams, lasers, and movers through Core create spectacular effects. Plan lighting around your fog density. 🎯 Manage airflow. Core's balanced hang time responds to ventilation. Want more persistence? Reduce air movement. Want faster clearing? Increase airflow. You can push it either direction by managing the room. 🎯 Burst, don't flood. For most indoor use, periodic bursts with pauses produce better results than continuous output. Build atmosphere, let it distribute, top up when it fades. Exception: large-volume spaces that need sustained output to reach density. 🎯 Keep your machine clean. Core is residue-free and gentle on hardware, but regular maintenance still matters. Flush after extended use, clean the tank, follow manufacturer specs. 🎯 Know when to upgrade. Core tells you when it's not enough: constantly fighting lingering fog? → Mirage. Refiring every few minutes? → Eternal. Wind destroying your outdoor fog? → Endure.
