Equipment and dry goods ship at their own rate. Free overnight shipping begins at $349 in qualifying livestock, so this item does not count toward that threshold and never receives the $10 livestock packing fee. Dry-goods shipping is calculated at checkout from the configured carrier rates.

We ship within the continental U.S. Alaska needs a shipping quote before you order, and we cannot ship to Hawaii — get in touch first.

Description

Neptune’s optical level sensor: no floats, no moving parts, nothing to stick — it sees water level and tells your FMM. The building block of reliable ATO and auto-water-change logic.

We standardized on optical sensors in the shop years ago and floods stopped being a category of problem. Pair two for run + failsafe; we’ll share the programming.

Shipping & Returns

Equipment and dry goods ship at their own rate. Free shipping at $349 or more applies to qualifying livestock only — corals, fish, inverts and live copepods. The $10 box & handling fee is a livestock packing fee and does not apply to dry-goods orders.
All sales are final on equipment and dry goods. We are a retail store, not the manufacturer.
Register your product with the manufacturer and keep your receipt — their warranty is how a faulty unit gets replaced, and they are faster at it than a shop could be.
Not sure who to contact for a warranty claim? Call us and we will point you to the right place.
