We’re back for the 280th time. Our guests this week are Matt Wandell, Richard Ross and, for the first time, Nick Yim, from the Steinhart Aquarium at the California Academy of Sciences. Lots of subjects this week, but the big one is the new twilight-zone display at the aquarium and what it’s like to dive deep for new species. If you enjoy the show, please tell others.

Maintaining stable parameters in the accepted range is much better than chasing “ideal” numbersQuestionI’m having an issue with the calcium and alkalinity levels in my reef tank. Right now, the calcium is at 380ppm, which is at the low end of the acceptable range, and the alkalinity is at 10dKH, closer to the high end of the acceptable range. I’d like to get the calcium up over 400ppm so I have a greater margin for error. But whenever I add more calcium supplement than usual, I notice that the alkalinity level drops afterward. Any idea why this is happening? Is it coincidence or cause-and-effect?” – Submitted by Ross C.

Water chemistry is a complex subject, but it is also an incredibly important one. It governs every factor within your aquarium and is pivotal to the health of the animals living in it. While there are a good deal many other water parameters to bear in mind, we have selected those which we believe to be the most important in saltwater aquariums. This guide will highlight those water parameters that we feel saltwater fish keepers should most be aware of. It will also explain how to go about adjusting the levels of these parameters in your tank. pH Fluctuations in pH levels can dramatically affect the health of the fish in your tank. Moreover if you have a reef tank then your occupants are likely to by AquaNerd | Jun 15, 2016 | Corals, Reef, Science
Garf Bonsai Acropora (A. valida) The origins of the name Garf Bonsai go way back to when hobbyists, collectors, coral farmers and scientists were just beginning to create names for specific species, color variations and lineages of collectible corals. Among the first corals to be named was the Acropora Purple Monster in 1995 when Steve Tyree grew it from a small colony which he had obtained in 1992 (which happens to be the same year I found the “nub”…. more on that next week). The GARF Purple Bonsai has always been a highly prized and sought after coral in the reefing community. It’s bright green polyps and purple skin are hard to match when compared to more common color morphs of A. valida, making this our featured coral
