The GEX Master Clear S for Nano and Small Tanks
The Master Clear S is the compact member of the range, sized for the nano and small tanks that fit a study desk or a narrow HDB shelf. Its smaller footprint glides into tighter corners and around aquascape hardscape where a larger magnet would knock rocks or crush carpet plants. We find it ideal for shrimp bowls and betta cubes where you want spot algae control without disturbing the whole layout.
Warm SG room temperatures push fast film growth on small volumes of water, and small tanks show smear and dust algae prominently because the viewer sits close. A short pass every couple of days keeps the front pane crisp. Keep the cleaning face clear of substrate to avoid dragging grit, and rinse then air-dry the pad afterwards so our humidity does not breed mould inside a closed cabinet.
For best results, treat it as part of a wider routine rather than a fix on its own. See the full cleaning-maintenance selection, and combine it with our glass cleaning guide and weekly maintenance checklist.
