Cleaning up around the house...
Danner Mag-Drive Supreme 3 350 GPH Water Pump - $50
Only water tested. Tried to build a closed loop system in a nanocube and ended up going to a larger tank.
150 Watt 20000K Metal Halide Bulb - Radium, Double Ended - $50
Used for 1 month before I got a great deal on LEDs and switched.
Coralife Aqualight Advanced Tank-Mount, 150 W 14,000K HQI - $100
I'm the second owner. Used for about 6 months before switching to LEDs. I modified to so that you could run bulbs other than the 14k coralife (added special glass to prevent coral from burning). Bulb was used for about 8 months total, so it could use a new one in a couple months.
Algae Free The Piranha Float - $35 - SOLD
Used for 3 months. A friend sold me his Hammerhead Float and I don't need 2, so here I am selling the Piranha. Probably the best magnet cleaners I've ever used!
SCWD - Free with purchase - SOLD
Tried to use when I was plumbing the closed loop on a nanocube. Not sure if it still works or not.
