View Full Version : Nano overflow box - up and running update

09-02-2011, 03:39 AM
I have a 5 gallon standard hagen non drilled nano. its been running for 6 years and this summer i have had heating swings , probably due to the higher humidity from all my other tanks. I have a frag tank running off my main display right beside the 5 gal and thought it be nice to connect the nano to this system. Because its not drilled can i use a small overflow system to do this? Im not sure how overflow boxes work. Id need some way to ensure no overflow. The drain off could be plumbed into my main sump no problem but would need a pump to add water from the frag tank.

anyone done something like this.

One of these would be perfect for you.
Just make sure your return pump is giving it 200 gph or so and this should never lose siphon.

Got my overflow up today , its great, no noise, im fiddling with level, its got a auto syphon so if power goes out it restarts, i take water now from my main system, - no more water changes in it, and stable temp plus manual top ups , should be really stable, its like a 250 gal nano.
Heres a photo of the nano and my frag tank beside that it draws from the frag tank is fed from my main tank , the other photo.
thanks for the tips..
