Cable: 15' (5m) with standard alligator clips (special plug-ins for most of our applications), 6.5' (only on 30W/40W/50W)
Removable filter on 2W/6W/10W/20W
* Optional: Flow stabilizing unit (Capacitor unit which boosts water pressure, steady flow in case of momentarily sunlight shortage or too weak) $10
Accessories: 5 different spray pattern heads for 2W & 6W, 6 heads for 30W/40W/50w; 2 heads for 10W/20W 
For clear and salt water use applications only. These pumps' performance will be reduced if being used with lower wattage panels. Ex: 6W pump can be used with 5w panel
