I have spent the last decade running saltwater tanks in my home and our team's 600-gallon research system at Aquamarine Power, and I can tell you from experience that choosing the best fish food for saltwater fish is the single most impactful decision you make for your tank's long-term health. We tested these eight products […]

Finding the best frozen fish food can completely change how your aquarium inhabitants eat, color up, and behave. I have spent years testing different frozen and freeze-dried foods across community tanks, species-only setups, and breeding projects. The difference between a quality product and a cheap one comes down to protein content, cleanliness, and how your […]

I've raised clownfish fry, kept mandarin dragonets, and bred freshwater dwarf cichlids over the last decade, so I know the pain of watching a picky fish refuse every pellet on the market. The single best upgrade I ever made was hatching my own baby brine shrimp. After testing 8 popular models across reef tanks and […]

When my first zoanthid colony shrank from 30 polyps to 9 in a "fed daily" tank, I learned the hard way that picking the wrong coral food can quietly undermine a reef. After running 's reefing community through side-by-side tests in 12 different reef tanks over four months, our team pulled together the best coral […]

I've been running reef tanks for 11 years and fragging coral for 8 of them. During that time, I've watched frags slide off cheap racks, scratched glass with poorly sealed magnets, and lost colonies to plugs that didn't fit. That's why I built this guide to the best coral frag racks available in . Our […]

I've been dipping corals in my reef tank for the better part of a decade, and if there's one thing I've learned the hard way, it's that skipping the dip can wipe out months of investment in a single night. The best coral dips aren't a luxury; they're the cheapest insurance policy you can buy […]

After running six mixed-reef systems over the past three years and testing more than 25 dosing products, I learned the hard way that not all reef dosing supplements are created equal. The best reef dosing supplements keep calcium, alkalinity, and magnesium stable so SPS corals actually grow instead of slowly bleach, and they do it […]

I've been running reef tanks for over a decade, and the day I installed my first calcium reactor changed everything. Before that reactor, I was dosing two-part supplements twice a day just to keep alkalinity stable. After? My SPS corals grew faster, my water parameters stayed rock solid, and I got my evenings back. A […]

Running a reef tank means chasing two numbers constantly: calcium and alkalinity. I've kept SPS-dominated reefs for over a decade, and the single piece of gear that changed my nightly dosing routine was the best kalkwasser stirrer I could find. Kalkwasser, which is calcium hydroxide mixed into RO/DI water, is hands-down the cleanest way to […]

I've kept freshwater and saltwater tanks for over 15 years, and I've lost entire tanks to ich and velvet because I skipped quarantine. That single lesson is why I now run a dedicated QT for every new fish and every sick fish that shows symptoms. In this guide, I'm walking you through the best quarantine […]
