I bought myself this bandsaw over two years ago at the Denver MACNA. It was basically a gift to myself, but I never opened the box until two weeks ago when I started fragging some corals at last. It's pretty impressive, and hence I had to make a video about it. by Marc Levenson | Mar 19, 2017 | Science, Video
I was way too busy last week, so that video is a few days late. But I had a pretty decent excuse... Here's the Behind The Scenes footage from the Birch Aquarium in La Jolla, California. by Admin | Sep 16, 2016 | MACNA, Science
Last weekend at MACNA, everyone wanted to see Jim's new invention, the Alkalinity Monitor. Here's my interview with him where he demonstrated and explained how it operates. A gizmo measures alkalinity all the time, and if so programmed could text you with important updates... interested yet? by Admin | Jan 5, 2015 | Corals, Fish, Science
You set up your tank, buy some shiny new lights, plug them into timers and then wait... how long should they be on? What will match your routine? What about the health of your reef? Fish and corals in nature are very aware of the daily cycle, so much so that if you purchase a wrasse from another part of the earth, it will still be on that schedule. I've purchased wrasses in the past that stayed in the sandbed way longer than expected, emerging hours after the lights came on because their internal clock was still calibrated to the previous time zone. After a couple of weeks, it would reset so precisely that it would circle and hover over the perfect spot mere seconds before the lights shut off. Pretty fascinating to watch, I have to tell you.If you have a simple system with T5 bulbs, your options may be limited to how many bulbs you can turn on at a time by Marc Levenson | Nov 10, 2014 | Corals, Fish, Invertebrates, Science, Tanks
I wanted to talk about LEDs for a few minutes. I've had the Radion Gen 2 over my anemone cube (60-gallon aquarium 24" x 24" x 24") for the past 12 months. As a light, it functions perfectly. Is it the best fixture ever? My feelings are a tad mixed, and I'll discuss why. The light itself provides sufficient lighting for anemones, SPS, LPS, gorgonians, zoanthids and even a T.
