Neptune A3 Apex Pro Base Unit

A3 Apex Pro Base Unit

Maybe your original base unit was damaged, or you’re upgrading an older setup to the A3 platform. Either way, this A3 Apex Pro Base Unit is exactly what you need. Plug all of your current Neptune Systems accessories into it like the EB832 Energy Bar, Apex modules, or pH and temperature probes. If your tank already runs on Apex, this is the easiest way to upgrade or get everything back up and running without having to buy the full controller kit.

Warranty & Support

This product carries a 1-year manufacturer warranty on hardware from the date of purchase. Probes are consumable items and carry a 90-day warranty.

Warranty support is handled by us directly. Message our WhatsApp support with your order number and we will diagnose the fault first. Most cases are solved by replacing a single part, so you rarely need to send the whole unit. If the item does need to come back, it ships to our Delhi warehouse, and courier cost in both directions is borne by the customer. Your GST invoice is valid proof of purchase for the claim.

Backorder & Dispatch Timeline

This item is stocked to order. Back-orders are consolidated and placed with our overseas suppliers once a month, on the last day of the month, and all such orders are shipped before the 15th of the following month.

Back-orders cannot be cancelled once they have been placed with the supplier. If you cancel before that, payment-gateway charges of 2% plus GST are deducted and the balance refunded. In the rare case a supplier cannot fulfil the item, we will offer you an alternative first, and refund in full with no deduction if you would rather not take it.

Setup & Use

This replacement A3 Apex Pro base unit comes with pH 7 and pH 10 and salinity 53,000 calibration solutions. Use it to upgrade from an out-of-warranty A1, A2 or A3 base, or to keep a spare. Plug your current Neptune modules and probes into it.

Returns & Replacement

Returns are accepted within 7 days of delivery, provided the item is unused and in its original packaging. Manufacturer-sealed items cannot be returned once the seal is broken, and sale-priced items are not refundable.

If your item arrives defective or damaged, message us on WhatsApp with your order number, or email us if you would rather, and we will replace it. Approved replacements are delivered within 3 to 5 business days. Transit damage is covered by insurance on every shipment. If tracking shows delivered but nothing reached you, tell us within 48 hours, which is the reporting window Indian couriers allow. Damage caused during installation or use is not covered; replacement spares for such cases are chargeable.
