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 on a magnet mount: reads water level with no moving parts to stick, and repositions in seconds when you change your sump. Pair two with an FMM for the gold-standard ATO — one to run it, one to catch a failure.

Magnet-mounted optics are all we use for top-off in the shop. Ask us for the two-sensor failsafe layout — cheap insurance against the classic flood.

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.
