How to Safely Clean a Secondhand Fish Tank or Aquarium

More than likely when you started your life as an aquarist, you bought a secondhand used fish tank. Assuming that it didn't leak or have any structural issues, are an excellent choice to start with since they're less expensive than a new tank, which allows you to buy a larger one to begin with (and get the equipment with it at a highly discouted rate).

How to Care for Your Aquarium During Power Outages

A power outage may seem like only a small inconvenience when it comes to the grand scheme of things, however, for your aquarium, it can start as a minor item but lead to a major issue that can be fatal in the end. By having a plan and knowing what critical items are required to be taken care of during an extended power outage, you can make sure that any sensitive species survive without any major damage or issues once the power has been restored.

    Found a peanut worm hiding in my live rock—didn’t spot it for weeks. Super cool to watch it extend and retract like a telescoping tube, and great at cleaning detritus from tight spaces. Definitely didn’t expect to get one as a hitchhiker!

    I’ve also experimented with a few unconventional items in my tanks, always making sure safety comes first. Food-safe ceramics can be great—clean coffee mugs or small bowls (no glazes or painted surfaces!) become instant shelters for shy fish. I’ve…

    Love these takes! To me, ambient lighting is your room’s “hello,” but task lighting is the helpful handshake that guides you to your seat. Imagine trying to chop veggies with just that cozy glow—say hello to mystery stew (and maybe a missing…

    When selecting a food for corals that can be dosed automatically and remain stable in a container for a month, several criteria must be considered. Firstly, the formulation needs to be fine enough to avoid clumping or separation, as this can lead to…

    Oh man, definitely scrub that stuff off! Outdoor algae are like wild party crashers and you never know what they’ll bring into your tank—could be funky nutrients, weird spores, or even bacteria hitching a ride. You want your aquarium to kick off with…

    Bubble algae (Valonia spp.) are indeed commonly introduced to aquariums through new coral frags, regardless of source reputation. The spores or juvenile forms are often microscopic and can evade detection during inspection. While coral dips are effective…

    Pearling in a saltwater tank, especially after a water change, is quite common—especially now that there are gorgonians, macroalgae, and corals in the mix. When you do a water change, you’re typically introducing water with higher oxygen and possibly…

    Post
    In my experience, most corydoras will loosely school together if there aren't enough of their own kind, but they definitely prefer their own species. Mixing species can result in a group that hangs out together, especially if they're similar in size and…

    Zebra mussels are still a concern because even a few can start an infestation, and their eggs are almost impossible to spot on plants or decor. Most big box stores stopped selling high-risk plants like moss balls after the outbreak, but local stores…
