Mini PVC Overflow and Sump for 2.5 Gallon Marine

Postby gminor » Mon Dec 05, 2011 2:43 pm

This mini pvc overflow and sump were made from 1/2 inch and 1 1/4 inch diameter pvc, a 16 oz food container, and some traditional aquarium hardware.

- 1 16 oz Rubbermaid food container
- 1 Marineland 10w submersible heater
- 1 Maxi-jet 400 powerhead with 12oz Dasani water bottle. Filter floss inserted thru opening cut in bottom of bottle.
- A few feet of airline tubing
- pvc overflow and return assemblies improvised to fit the aquarium
- 1 inch of 3/16 inch rigid tubing installed in pvc elbow to draw air from overflow.
- 1 Aqueon 2.5 gallon aquarium

The blue line in the food container indicates ideal water level while system is in operation to avoid flooding in the event of a power failure.


Output from the powerhead is pointing straight up on purpose.


Inserting the pvc return. The straight tube loosly sits on top of the powerhead return.

Still looking a little cloudy from installing the overflow.

Water is looking much cleaner after just a few minutes.

Here's a short video of the aquarium with a pair of green chromis damsels, a few reef crabs and a some green star polyps settling in to their new space.
