Manufacturer Info

Marine Depot was started in 1998 by a self-professed reef geek and pre-med student Ken Wong. Ken envisioned a one-stop shop where customers could find everything they needed, from technical product specifications, reef aquarium information, expert advice on the hobby and friendly one-on-one customer support. Having grown from a one-man crew to being one of the world’s largest suppliers of reef and marine aquarium products, this very core philosophy still lives strong in the Marine Depot culture 20 years later.

Bad Unit? Cheaper Elsewhere
reviewerbadge
PROS
Easy to return, quick shipping, customer service
CONS
Couldn't calibrate, crooked line, cheaper other places
REVIEW
It's possible that I had a bad unit, but the line was completely crooked and it would not calibrate properly when turning the knob. I ordered an identical unit from somewhere else (literally had the same typo in the instruction manual) for half the price and it worked perfectly.

REVIEW
I spent a few hours looking up reviews on refractometers and finally settled on this one. The product itself is great and my reading matches my local pet store so that is a good thing.
