6 Steps to Stable pH in a Saltwater System

Like other water parameters in your marine aquarium, stability is also important with pHStability of water parameters is essential to success with marine aquariums, especially when it comes to keeping sensitive invertebrates. Among the various parameters that hobbyists often struggle to maintain at an appropriate level is pH, essentially a measure of how acidic/basic the water is. While the ideal target for pH in a marine aquarium is somewhere in the range of 8.2 to 8.4, it’s more important to maintain a stable pH, even if it’s slightly outside this range, than to constantly chase a particular value within the range. The challenge is, owing to various natural processes going on in the tank, the pH in a closed aquarium system usually drifts downward (there are exceptions, of course), so the hobbyist must take certain steps to counteract this trend. Here are six of them:1) Perform regular partial water changes Regular Saltwater Smarts visitors must be pretty tired of hearing this by now—as I recommend water changes for virtually anything that ails a saltwater system. But the truth is, nothing promotes stability of parameters, pH included, better than routine partial water changes. Every time you replace old salt water with new, you’re not only removing dissolved pollutants and replacing components vital to the health and growth of your livestock, but you’re also replacing compounds that buffer the water against shifting pH (carbonates and bicarbonates)

Tokyo Sea Life Park Aquarium: Over 150 Mysterious Tuna Deaths

tunaTokyo Sea Life Park Aquarium staff are currently baffled. Of the 160 Bluefin Tuna which have lived in the exhibit up to November of last year, only one fish is left alive as of Tuesday. An investigation is under way to try and figure out why the Tuna are perishing at such astonishing levels. Lighting, noise vibrations, toxins, and water quality are being studied to see if there is any potential risk factors. There was a virus detected in the examined dead fish, but it wasn’t the type to cause fatal deaths. Tokyo Sea Life Aquarium created a Tuna breeding program which was started over two decades ago, in 1989, with the intent to ‘reproduce aquatic habitats in the world’. Tuna have been kept in the aquarium since then. It was only as of November of last year that the Aquarium ever noted the tuna dying in such vast quantities. Bluefin Tuna are an endangered species, mostly due to over fishing of the ever popular sushi cut.… More:

Six Months With the Maxspect Gyre XF-150

reefs.comGyreReviewOn August 31, 2014 I met with the awesome crew of Coralvue at MACNA in Denver. Although I worked the show, they were the one booth I had to visit in order to catch a glimpse of the highly anticipated Maxspect Gyre XF-150 in action. Overall I’m not generally excited for most product releases these days. Many are subtle improvements on existing products that technophiles go bonkers over. But this thing turned my idea of flow upside down well before I had seen it in person. For years many of us had attempted to create gyre flow throughout our aquariums to keep detritus in suspension and replicate a natural environment for our animals. Sometimes it was successful, other times not even close. Regardless right off the bat I could tell this thing was a drop-in solution for any aquarist wanting to achieve amazing flow.… More:

Update On World Aquarium: Passes Re-Inspection

544ab0bfa1bef.image (1) The World Aquarium,a nonprofit facility, has passed a re-inspection as of Friday and will remain open. This good news comes after the Aquarium was cited with a plethora of rather egregious violations last month that one would not equate with standard of care expected at a public aquarium. The violations alleged included contaminated water, empty fed bowls and general lack of cleanliness. The Aquarium is currently located inside downtown’s popular City Museum, and the aquarium has stated they will stay open and in business at least until Labor Day. Rick Erwin, the executive director of the City Museum, had previously stated that he asked the Aquarium to vacate, citing unpaid rent. On Saturday, after hearing the news that the Aquarium would stay open, Erwin stated: “If they passed their inspections, great. We’re happy for the animals.… More:
