From the boat, there’s nothing remarkable about the place — just choppy water and a white mooring ball, a few miles offshore. But once we’re underwater, I can see the rows and rows of PVC trees, suspended above the sand in a grid that stretches away into the distant murk. This is a coral nursery. Each tree bears a ripening crop of a hundred or more pieces of coral. The smallest fragments are pinkie-sized, twirling on their tethers as other divers kick by; the largest hang like many-limbed chandeliers, turning slowly in the current. When I get closer, I can see the individual polyps, the anemone-like creatures that make up each fragmented colony. Nestled in the crenellated openings in their solid skeletons, they by Saltwater Smarts | Dec 15, 2015 | Equipment, Fish, Funny, Reef, Science, Tanks
Ralphie checking out his brand new Red Ryder BB gun on Christmas morningBack in the sixth grade, I had my sights set on a BB gun for Christmas. No, it didn’t necessarily have to be the Official Red Ryder Carbine-Action, Two-Hundred-Shot Range Model Air Rifle so famously coveted by Ralphie in A Christmas Story. Make and model were of no consequence. Besides, that popular holiday film hadn’t even gone into production yet. I just needed something to keep up with my good friend, Dan Rogers, who was already duly armed with a pump-action Daisy. Dan and I spent many of our waking hours (and more than a few of what were supposed to be sleeping hours) exploring the vast (it seemed back then) ravine behind his house, and there were definitely things lurking in the forbidden recesses of that ravine that needed shooting—like old beer cans and…older beer cans. So any time we weren’t building campfires, fighting each other with makeshift quarterstaffs on fallen logs, or detonating firecrackers, we could be found picking cans off any level horizontal surface with BBs by Saltwater Smarts | Dec 10, 2015 | Conservation, Equipment, Reef, Science
Drip, drip, drip…there are a number of options to reclaim reverse-osmosis waste waterWhile reverse-osmosis units are among the more practical, affordable means for producing purified tap water suitable for sensitive reef systems, there’s no question that they tend to generate a lot of waste water relative to the volume of purified product. In fact, they often produce upwards of four gallons of waste water for every one gallon of purified water. It’s only natural for conservation-oriented hobbyists to look for ways to reclaim this waste water and put it to meaningful use rather than send it swirling down the drain. But finding realistic ways to use all that water isn’t as simple as it seems, especially if you have a relatively large aquarium system and, therefore, need to produce a hefty amount of RO water on a fairly regular basis.The usual advice is to use the waste water to give your plants or lawn a drink. These are certainly valid options, but let’s face it, you’d have to have an awful lot of plants to keep pace with all the waste water produced. And as far as watering the lawn is concerned, I’m sure someone more inventive than I (which isn’t saying much) could find ways to do this efficiently using RO waste water, but I haven’t figured out a method that would work for my yard yet. by Saltwater Smarts | Dec 8, 2015 | Equipment, Fish, Reef, Science
Let’s face it, if we marine aquarists had our way, every gift we received during the holiday season would be hobby-related. Trouble is, ours is such a specialized pastime that few, if any, of our loved ones really understand it or have any idea what sort of item would be appropriate to buy—that is, of course, unless we sneakily supplant those visions of sugar plums dancing in their heads with some good gift ideas.Last year at this time, we posted a list of items that most marine aquarium hobbyists would be happy to discover under the tree come Christmas morning, including sea salt, aquarium tools, a refractometer, fish food, water parameter test kits, and reference books. This year we’d like to expand upon this list with a few more great ideas. Now, to help your non-hobbyist family members and friends “discover” this list, you might need to print it out and hang it on your refrigerator, tape it to your computer, tuck it into the pages of Look Magazine, or simply leave it lying out in the open somewhere that the targeted gift giver is likely to happen upon it. So, here in no particular order is this year’s list. Note that if you want to surprise the reekfeeper on your list with any of these items, you may need to do a bit of sleuthing or ask a few seemingly innocent questions ahead of time to determine exactly what to buy. #1 RO/DI replacement components If your hobbyist loved one uses an RO/DI system to purify tap water, he or she will most assuredly appreciate receiving some extra carbon blocks, sediment filters, a deionization cartridge, or an RO membrane (if you can find out whether the membrane currently in use is nearing the end of its serviceable life). You may even be able to purchase all the replacement components for the system in a single cost-effective kit. by Tami Weiss | Nov 29, 2015 | Conservation, Seahorses
Seahorses can be found along many shorelines frequented by people. Photo by Caio R. N. Periera cc-by/nc So you’ve found a seahorse, and you want to keep it. Or maybe you stumbled across one washed ashore, and are unsure what to do next. This question comes up from time to time. It’s not frequent, but it does happen enough that I wanted to provide some guidance. Release It! The best thing to do is to release the seahorse back where you found it, if at all possible. The sooner you can do this, the better off the seahorse will be. This is especially true for those found washed up on the beach, as can happen from time to time due to seahorse’s poor swimming abilities.
