SC135 – hand pump for water changes

This hand pump is designed for aquarists who change water often in smaller tanks and find hoses and buckets too time-consuming for routine maintenance. Its syringe-like body lets one person remove and refill up to 0.9 L of water in a single stroke cycle, without setting up a siphon.

Why it matters

• Draws up to 0.9 L of water from the tank directly into the chamber, so no hose or bucket is needed.
• The same device is used to add fresh water, so one tool handles both steps of a change.
• The whole operation takes up to 5 seconds, which makes small partial changes practical on a daily basis.
• The manufacturer's guidance gives a clear routine: one full pump every third day for a 20 L tank, every second day for 30 L, and daily for 50 L.

What it works with

The pump is intended for routine partial water changes in aquariums, with the manufacturer's dosing guidance covering tanks from 20 L to 50 L. Its 0.9 L capacity is matched to a single pump per change at those volumes, so it fits best in small and medium tanks rather than large systems.
