One of the topics I wanted to address as a full video is biopellets. Short answer: they work. Earlier this year, nitrates spiked in my reef and despite lots of effort it didn't get them down and keep them down, so I opted to get biopellets running again on my 400g reef.
I've been uploading videos to Youtube pretty regularly lately. Did you happen to catch the Youtube Live show last week? Here's the latest one, so if you've missed a few you need to get caught up. I describe how I set up the 60g frag system I built myself, including all the acrylic work.
