Five Reefing Trends that we don’t do anymore
You need to have a good sense of humor in this hobby when you’re told for decades to get rid of nitrate, only to be told now to dose it! Here are some natural filters, fashions, and nutrient control methods…
Northern Star Coral shifts microbial communities while dormant
A study led by the University of California has found that microbial communities within the Northern Star Coral, Astrangia poculata, shift while it enters dormancy, providing it an important seasonal reset. The work carried out by Assistant Professor Anya Brown…
10 items that make reefkeeping easier
We wouldn’t run a reef tank without these! RO Unit Filling up and maturing your tank with tap water is fine, but for topping up you need a pure source of water that will replace evaporation without making any levels…
