Dupla Marin calibrated hydrometer reads specific gravity in high resolution
It’s been a looooong time since Dupla made waves in the reef hobby outside of Europe but its new Dupla Marin Hydrometer, a new high-precision and accurate hydrometer, might get them back on the map. You may be asking yourself “why…
5 Tips for Maintaining Stable Salinity in a Saltwater Tank
