Neptune magnetic Optical Sensor mobius Did you know that LED's

Did you know that LED's lose around 22% of light and therefore PAR emission over years of constant use

and creates a smooth broad stream of ocean-like current

and shells in subtle shades

We developed our Calcium Reactor 1 & 2 supplements to provide these additional trace elements in the ratio required

coralline and calcareous algae

Neptune magnetic Optical Sensor mobius Did you know that LED'sOPTICAL SENSOR This sensor plugs into your FMM and, using reflected infrared light, will signal your Apex when it changes state from being wet to dry or dry to wet. This sensor can be used for constructing your own ATO (auto top off), as a high level warning sensor in your sump, water storage level sensor, and much more. Included are a fastening nut and silicone washer. These sensors are sold individually.
