How to Make a CO2 Scrubber to Raise pH

It’s that time of year, when it’s freezing outside and toasty inside.  That means many houses (especially newer ones) start to accumulate carbon dioxide (CO2).  For aquarists, this often translates into a reduced pH during the winter.  Rather than opening a nearby window or adding potentially troublesome supplements, here’s an inexpensive and easy solution! Supplies: …

Rescuing Dying Corals: Lithophyllon

I received a call one day that a local fish store (LFS) employee had overdosed the reef tanks with a chemical used to treat flatworms (I was not told what chemical it was).  They asked if I wanted to try to save some of the corals.  When I arrived, honestly, I was shocked at how …

LEDs – The Introduction (Part I)

For my graduate engineering thesis, I decided to attack a known problem in my biggest hobby rather than in my actual career field (let’s face it, writing about aquariums is a lot more fun for me!)  Coincidentally (or maybe it was fate?), the metal halides on my display aquarium died at the same time.  So, …

Swim Bladder Inflammation in Fish

Swim bladder problems are somewhat uncommon in saltwater aquarium fish.  They’re commonly found in deepwater fish that are not properly decompressed, sometimes in fish with digestive problems (commonly due to a poor diet), and occasionally due to the presence of viruses, bacteria, and/or parasites. Treatment Background If the fish was not recently acquired (within a …

Acanthastrea-Eating Spiders

Here’s another one for your nightmares!  For years I had heard rumors of a stealthy Acanthastrea predator, but I had yet to find one (to my relief.)  A while back, I attended a coral fragging demonstration, and along with my frag freebie, I also received these lil buggers. Rumor has it that these spiders tend …
