During my initial purchasing binge I bought a portable HM Digital Combo Meter 100 Waterproof EC/TDS/Temp meter, however I've since bought an inline TDS meter to track TDS both before and after my RO/DI unit, so I don't need this. Completely new in box, never used, I paid $54 for it on eBay. I'm asking $35.
Also managed to (somehow, I'm not quite sure) purchase two JBJ Ocean Pulse Duo Wave Makers. Since my gf only needs one for her nano, and I don't have a need for one (Reefkeeper 2 handles that for me *grin*) I'm looking to sell it. I paid $54.99 from Drs. Foster and Smith (*sigh* just saw 'em online for $44.99). Never been used, completely new in box, I'm asking $35 for it.
If you're interested in either then call me at 512-269-6138. Oh, and if you want 'em both, I'll sell them together for $60.

FEATURES
Measures electrical conductivity (EC), total dissolved solids (TDS) and temperature.
Three different calibration options (KCl, 442TM, NaCl), each with its own non-linear conversion factor.
Automatic Temperature Compensation (ATC) using three temperature coefficients
Waterproof housing
Measurement Range: 0-9990 µS; 0-8560 ppm (auto-ranging).
Digital Calibration (push button)
Auto-off function, data-hold function and low-battery indicator.
Display: large and easy-to-read LCD screen includes simultaneous temperature reading.
Factory Calibrated: (http://www.tdsmeter.com/calibration_maintenance.html) The COM-100 meter is calibrated with a 1413 µS solution. The meter can be recalibrated with digital calibration using the push buttons, rather than a screwdriver.

Weight without case: 90.7g (3.2 oz)
Description
Creating Motion in Captive Oceans
The Ocean Pulse Duo and Quadra are an innovative wavemakers that were specifically designed to replicate the natural alternating rhythms of tides and currents for home aquariums.
These wavemakers instantly create turbulent flow patterns with adjustable alternating cycle times from 10 seconds - 6 minutes. All models are equipped with an adjustable dial(s) for quick and easy set-up for virtually all types of inverts, corals, filter feeders and fish who will gain immediate benefits.
Always research specific flow requirements for individual animals before making adjustments.
Water movement is vital for the success of invertebrates, anumals with symbiotic algae, filter feeders anf fish. The natural currents in the ocean bring random flow and wave sycle patterns that provide nourishment while suspending waste particles for filters to effectively trap.
Benefits of Replicating Wave Patterns
Recreating water movement is essential for captive animals within our aquariums for long-term success. By installing the Ocean Pulse Wavemaker you will immediately be rewarded, as you see you aquarium transform into a cleaner, healthier and more natural environment.
Benefits
Provides oxygen rich water to entire aquarium
Provides more stable water temperature
Creates desirable turbulant flow patterns only found in nature
Flushes "dead spots" of detritus and accumulated waste
Increase fish activity
Stimulates coral and invertebrate growth
Allows corals amore exposure to light
