Voonline Top-Off Water Tank for Stable Levels

This acrylic reservoir clips onto the rim of your main tank and uses atmospheric pressure to automatically top up evaporated water, keeping the level steady without electronics or floats. In Singapore’s warm 27-29C rooms, open-top tanks lose water to evaporation noticeably faster than in cooler climates, so a passive refill like this saves you constant manual top-ups and keeps parameters from drifting between water changes.

It suits main tanks with glass up to about 16mm thick. Fill it with dechlorinated water, since our tap supply is chloraminated and refilling with untreated water defeats the purpose. Keep the main tank level at or above the marked logo line on the clamps so the system primes correctly. It tops up evaporated water only; you still need regular water changes to export waste and refresh minerals.
