What’s Your Aquascaping Rock of Choice?

There are a number of choices when it comes to the rock you use for aquascaping, my personal favorite is live rockToday’s marine aquarists have more options than ever before when it comes to the types of rock used to aquascape their tanks—from live rocks, whether aquacultured or wild-harvested, to all manner of dry rocks and even natural-looking man-made rocks. Each type has its advantages and drawbacks, and the choice that’s best for any given hobbyist depends on, among other factors, his or her aquascaping goals, budget, risk tolerance, and desired level of control over the system’s biodiversity. Call me old-school (or Lord Admiral Jeff of the Universe—whichever you prefer), but my aquascaping material of choice has always been live rock, whether comprising the rockwork entirely or at least a major portion of it. Here’s why:Fascinating biodiversity Live rocks come loaded with organisms that emerge or hatch out for many weeks and months—even years—after they’re added to a tank. Various “pods,” fan worms, sponges, tunicates, mollusks, worms, coral colonies, macroalgae, and coralline algae are just a sampling of what might appear. And this process/progression is truly amazing to observe. I’ve never tried it, but I think it would be fascinating to set up a live-rock-only (LRO?) tank, with no fish or intentionally introduced invertebrates, and just sit back and watch what pops out of the rocks over time

Does Your Marine Aquarium Pass the Smell Test?

Your senses play as important a role in maintaining your aquarium as test kits and monitoring devicesWe marine aquarists depend heavily on store-bought test kits and devices for monitoring water quality and parameters (like the FishBit monitor we discussed here recently), but we’re actually born with some of the best tools available for figuring out what’s going on with our tanks—our innate human senses. With the possible exception of taste (I’d recommend observing the general admonition that you shouldn’t put your tongue on anything related to your aquarium), our senses can tell us quite a bit about the health and well-being of our systems—if we pay them heed, that is. Here are some examples of how:Sight Obviously, our eyes give us the most comprehensive information about our tanks, so we’ll start there. They reassure us that our livestock is healthy and behaving normally, getting enough to eat, and interacting peacefully; that there’s ample water movement in the system (evidenced by swaying corals, particulates kept in suspension, etc.); that the lighting system is fully functional with no burned out bulbs/tubes/LEDs; and so forth. But sight isn’t the only sense that’s helpful to the marine aquarium hobbyist. There’s also… Hearing Unusual or louder-than-normal sounds often indicate that something is wrong in an aquarium system. For example, a rattling sound coming from a submersible pump or HOB filter could indicate a broken or cracked impeller.
