💡 Always install a check valve between pump and tank — prevents water siphoning back into pump during power cuts. Required regardless of tubing material.
🧵 Installation Keys
Cut square with sharp scissors: Square cut = airtight connection. Angled cut reduces sealing surface and causes air leaks.
Cable tie if connections feel loose: Silicone grips most fittings firmly; if slightly loose on worn fittings, small cable tie seals it immediately.
Flush before first use: Rinse with clean water before connecting to established tanks; removes manufacturing residue.
Best value: 10m at ₹179 = ₹17.9/m; 1m at ₹29 = ₹29/m. For fish rooms and multi-tank setups, 10m always best per-meter cost. Unused silicone stores indefinitely — buy the longer length.
