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.

Q
The bulkhead has a drain diameter over 1",but it was supposed to come with a 3/4" drain. I'd need to plumb it to a return hose, but the threads are too fine for almost all adapters. What should I use ?

Q
So.......even though the bulkhead appears larger than 3/4", that must describe the ID of the PVC pipe that needs to be glued into it....plumbing gets easier after that ( I had thought it required a piece you screwed onto it)

Not enough adjustment to keep a high enough water level
REVIEW
I ordered this for my standard 29g reef tank and it works flawlessly. Very easy to set up and never loses syphon. I turn off flow daily for feeding and it starts right back up every time. I can truly say I have no worries about flooding my floor due to failure.

REVIEW
I bought this for a ten gallon nano I put together with a 5.5 gallon sump/ fuge. It's been running strong for just over 8 years. The only time I've had an issue is when I let algae grow up in the U tube. It never breaks siphon unless I cause it. It's never not started when the return pump is energiz...Read More

No instructions
REVIEW
I recently purchased the nano overflow box. So far its worked perfect for my DIY sump I did. The only reason I did not give it a 5 was due to lack of instructions and I did not have any tubing included to suck out the air on the bend. Other then that it has been a positive experience!
