Pico

I'm having a lot of fun and success with the Fluval Edge. It's a 6 gallon, not sure if that's pico, but it sure is small. I do a 1 to 2 gallon water change every week, run chemi-pure elite and purigen in the power filter, run a koralia nano for extra water movement, and have a 50 watt Eheim Jager heater that keeps it within a degree at all times.

 

The tank was $90($100 - 10% coupon). I added 4 Cree XP-E blue LEDs on a Meanwell driver. I also replaced the MR-11 halogen bulbs with MR-11 LEDs, but they both crapped out last week. I'll be cutting the whole stock fixture out or gutting it and building an all Cree LED fixture. I've got 10 lbs of sand and about 5 lbs of rock. I've got an overdue for updates build thread in the pictures forum if you want to look.

So it's:
Tank- $90
Lights- $50 or so(another $40 before I'm done)
K Nano- $30 or so
Jager Heater- $30
Livestock- hahah, don't get me started!
