What it is, and who it is for.

Neptune DOS Dosing Pump

QUESTIONS 07

Asked before checkout

The questions our support inbox actually gets.

Does it ship quickly?+

Orders placed before 2 PM ET on a business day leave the same day. Tracking is emailed the moment the label prints.

What if it's the wrong fit for my tank?+

Return it. 30 days, no restocking fee, refund to the original payment method. Better: tell us your tank first and we'll spec the system for free — half of all returns are sizing problems.

Who handles the warranty?+

We do. Everything carries the manufacturer's warranty and we run the claim for you — one email to us instead of a ticket queue.

How does the bundle discount work?+

Add items in the bundle builder: 2+ items saves 5%, 3+ saves 8%, 4+ saves 12%, and 5+ saves 15% off the whole system, applied at checkout.
