Stylophora are a less-challenging SPS coral that still provides a similar aesthetic to more difficult speciesStylophora are branching small-polyp stony corals from the Family Pocilloporidae. Stylophora shares that family with Pocillopora and Seriatopora, and the three together are the only genera in the family. As a result of their close relationship to one another, all three of these genera share quite a lot in common. What is immediately obvious is that their appearance is very similar. They are all bushy, branching corals, and even on close inspection, their polyps are nearly indistinguishable. So, this is one of the rare instances where observing the whole colony is more helpful than taking a close look. Stylophora vs. Pocillopora vs.
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. Answer Thanks for your question, Ross
