Drain Your Tank in 5 Minutes — Standing Up
Squeeze the bulb twice. The siphon starts on its own — pulling fish waste, leftover food, and mulm out of the gravel without sucking up substrate, stirring up clouds, or stressing your fish.
How One Squeeze Starts the Whole Siphon
No mouth-priming. No shaking the tube for five minutes hoping flow kicks in. A manual bulb pump handles the start so you can stay focused on the gunk, not the gymnastics.
➤ Manual Bulb Pump — Two Squeezes and It's Running: No mouth on the hose, no plunging the tube. Just press, pull, and water flows on its own.
➤ Fry Protection Net — Keeps Babies and Shrimp Safe: Built-in mesh on the intake stops fry, amano shrimp, and curious tetras from getting pulled up the tube.
➤ Precision Flow Valve — Slow Near Sand, Fast Over Gravel: Twist the valve to dial in the pull, or pause flow completely without lifting the nozzle out of the tank.
Vacuum About 30L in 5 Minutes
The 14mm hose moves real water — roughly 30 liters in five minutes once the siphon's going. Stand by the tank, watch the mulm leave the gravel, and let gravity do the heavy lifting.
Pick the length that fits your setup: 1.7m for a tank stand with the bucket nearby, or 2.6m for taller stands or a bucket across the room.
Surface Algae or Gravel Gunk? Switch Nozzles
Why Fishkeepers Switch to Flexora™
✓ Squeeze-Start Bulb: No more mouth-priming, no more shaking the tube hoping it catches.
✓ Fry-Safe Intake Mesh: Babies and shrimp stay where they belong — in the tank.
✓ Two-Nozzle Versatility: Duckbill for surface and corners, cylinder for deep gravel cleaning.
Water Change Day, Way Less Annoying
The hose is long enough that you can stand the whole time. Your knees, your lower back, and your Sunday afternoon will all thank you.
"Used the cheap plastic vac for two years and lost three neons to it. Switched to this and I haven't lost a fish to the siphon since. The bulb works first try every time." — Mark P.
It's the difference between dreading water changes and getting one done in the time it takes to brew coffee.

What You're Really Getting
Squeeze-Start Siphon
Two squeezes of the bulb and water starts flowing on its own. No mouth-priming, no shaking, no soaked sleeves.
Fry-Safe Intake Mesh
The cylinder nozzle's built-in net catches anything you don't want pulled into the bucket — fry, amano shrimp, gravel pieces.
Adjustable Flow Valve
Twist the valve to slow the pull over sand, speed it up over gravel, or pause flow without unhooking the hose.
Duckbill + Cylinder Nozzles
The flat duckbill skims algae from the surface and reaches into corners. The cylinder digs into gravel to lift detritus and leftover food.
175cm of Working Reach
Long enough to keep the bucket on the floor while the intake stays at tank level — no awkward angles, no spills.
