Overview
An auto top-off system is only as safe as its weakest point, and an unprotected gravity siphon is one of the more overlooked risks in a reef plumbing setup. The Neptune Systems ATK Siphon Break is a genuine replacement part for the Neptune Systems ATK Automatic Top-Off Kit, designed to prevent an unintended siphon from draining your reservoir into the tank.
It's a small, inexpensive part, but one that plays a real role in your ATO's overall safety.
Key features
- Genuine Neptune Systems replacement part for the ATK Automatic Top-Off Kit
- Helps prevent unintended gravity siphoning in certain equipment failure scenarios
- Simple installation as part of the standard ATK setup
Who it's for
Anyone running a Neptune Systems ATK who needs a replacement siphon break, or is setting up a new ATK and wants a spare on hand.
Setup & tips
- Install exactly as shown in Neptune's ATK installation guide for correct function
- Always keep your ATO reservoir positioned below the ATK module itself, as an extra layer of siphon protection
- Keep ATK tubing just above the waterline rather than submerged, reducing the risk of gravity siphoning
- Check the siphon break periodically as part of routine ATO maintenance
