- The siphon is designed for media beds where the maximum water level would be 9". The stand pipe can be adjusted about 2" for different water levels. For greater water depth the standpipe should be cut higher and the bell with hang properly on the standpipe but the bed will retain more water when fully drained.
- The included funnel is designed to fit on a 3/4" PVC standpipe (not included). The outside diameter of your standpipe will measure approximately 1".
- The siphon will tightly fit in a 4" gravel guard if the guard is carefully placed around the drain. We strongly recommend using a 6" gravel guard. (Not Included)
- Acrylic monitor window allows for easy viewing of the water flow!
- The normal color is WHITE. If you want it printed in black, please leave a comment while checking out.
- We have made our best effort to design this siphon to operate in most conditions. If the siphon doesn't start, try adding a 90 degree elbow under the grow bed (or a U-trap) or increase the water supply flow. If the siphon doesn't stop, try reducing the water supply flow.
- This is a 3D printed product so it doesn't look perfect but it's functional! Printed with PLA plastic.
- These are printed to-order so please allow a few days for delivery.
