The Marina Betta Waste Remover is a 29 cm hand siphon holding 30 ml, used to lift waste and uneaten food off the bottom of a small tank without disturbing the whole thing.

Key Features

• 29 cm long, which reaches the bottom of any of the Marina betta kits
• Holds 30 ml a go — enough to lift the waste from one spot before emptying
• Point and squeeze. There is no priming and no hose
• Sized for small tanks, where a full gravel vacuum is unusable
• Made by Marina, Rolf C. Hagen's entry-level aquatics brand and a sister brand to Fluval

Using It

• Squeeze the bulb, put the tip next to the waste, and release. The suction lifts the debris
• Do it every few days in an unfiltered tank. Waste left on the bottom is where the ammonia comes from
• It is not a substitute for water changes. A small unfiltered tank still needs a partial change every few days
• Rinse it in plain water after use and let it dry. Never wash it with detergent
• Watch where the tip is. A betta's fins tear easily

Good To Know

• In a tank with no filter, physically removing waste is the main thing keeping the water safe. This is a job, not a chore to skip
• 30 ml is small. A few squeezes is a spot clean, not a water change
• For anything bigger than about 10 litres, a proper gravel vacuum is quicker and does more
• Tap water must be dechlorinated before it goes back in
