Keraxis February 22, 2016 Share February 22, 2016 Just ordered an Eheim compact pump from Marine Depot. This will fit in the back chamber of the Fluval spec 3 replacing the stock pump and flows 80gph. Just thought I would share since it took me a while to figure out a pump that would. Dimensions are 2.1" x 1.4" x 2".... Gotta love those germans Link to comment Share on other sites More sharing options...
AlanM February 22, 2016 Share February 22, 2016 Nice, I'm using a Sicce Nano on mine that I bought from Avast. Same one they use on their smallest spyglass reactor. It also fits in the back. Link to comment Share on other sites More sharing options...
20LogR February 22, 2016 Share February 22, 2016 I really like the Sicce pumps, They are pretty much the only brand i'll use for the small pumps now. Link to comment Share on other sites More sharing options...
matt February 22, 2016 Share February 22, 2016 I have used larger versions of eheim compacts on my 46 and 90. I have found them bulletproof. Link to comment Share on other sites More sharing options...

What heater did you go with. I was trying to see if I even needed one but I am starting to think I will. Link to comment Share on other sites More sharing options...
AlanM February 22, 2016 Share February 22, 2016 I have some kind of little constant on heater that is a few inches long. Not sure the brand, but it might be an aqueon. I assume it's constant on because I have never seen it turn off, heh. It runs the tank at about 74 degrees and cooler at night, but it might do better if it was in a warmer part of the house.

Rosco's Reefs November 11, 2016 Share November 11, 2016 What specific pump model did you buy? I have a need for a really small pump. Thx in advance Just ordered an Eheim compact pump from Marine Depot. This will fit in the back chamber of the Fluval spec 3 replacing the stock pump and flows 80gph.

Brucenemours August 10, 2017 Share August 10, 2017 To add onto small pumps, I upgraded my pump in the Fluval Sea Evo XII. If anyone else has the same tank they know that the pump will do the job but doesn't have the best flow rate and fits very snug into the back chamber. The "factory pump" is rated at 134 gph I believe, or something around that. I upgraded to a Hydor Centrifugal pump. It is about half the size, quiet, and pushes 300gph. I am able to control the flow rate as well. The pump paired with a hydor nano powerhead pushing 240gph allows me to turn over the tank at most 40 times an hour. If anyone has a tank around the same size, and is looking to save a considerable amount of space, I highly recommend this pump. The dimensions are 2 3/4"L x 1 1/2"W x 3 1/4"H Link to comment Share on other sites More sharing options...
