How to Add Trace Elements to Kalkwasser
Kalkwasser has a lot going for it.
It provides a stronger pH boost than most two-part systems, doesn't increase salinity with sodium chloride buildup, may help precipitate phosphate, and is dramatically cheaper than many calcium and alkalinity methods.
Ice Water Temperature Calibration: Is This Legit for Reef Tank Thermometers?
We recently tested a variety of aquarium thermometers and probes against a surprisingly simple standard: ice water.
The question wasn't whether ice water is 32°F—we know it is when prepared correctly. The question was whether accuracy at 32°F tells us anything useful about performance around reef temperatures.
We Tested Hydrogen Peroxide Dips on Five New Corals: Duration vs Concentration | SR Labs
Hydrogen peroxide dips are one of those reefing tools that can be incredibly useful, but also far more aggressive than standard coral dips. That is exactly why we tested them on five soft corals and mushrooms to see what actually happens.
The goal was simple: compare duration versus concentration, identify which corals tolerate peroxide, and determine if it is a practical way to remove algae, worms, and other pests before adding frags to a tank.
