Using the Marina Flexible Tube Brush in Your SG Tank
We keep this brush on hand because the parts most people forget are the ones that quietly choke flow: filter intake pipes, lily pipes, spray bars and the corrugated hosing on canisters and hang-on-back units. In Singapore’s warm tanks, biofilm and algae build inside tubing fast, and a narrowing pipe drops your turnover before you notice. The long flexible shaft pushes through bends a rigid brush can’t reach, scrubbing the inner wall clean.
For best results we run it during a water change, after the filter is off, so loosened gunk doesn’t blast back into the display. Push the brush through from both ends of a hose, then rinse in old tank water rather than under chlorinated tap to spare your bacteria colony. It suits 12-19mm tubing common on most SG hobby filters, and a quick monthly pass keeps inflow and outflow consistent.
Pair it with the rest of your kit in our cleaning & maintenance range, and slot pipe cleaning into a routine using our aquarium maintenance schedule. For inflow and outflow specifics, our glass inflow/outflow cleaning tools guide pairs well.
