A Look at the Tunze Recirculation Pumps

Return or recirculation pumps have long been a part of the Tunze product offering. This past year Tunze has added a couple of new models.  This article will introduce the new pumps and also offer some general advice on Tunze product applications. Tunze offers 3 lines of recirculation pumps known as the e-Jet, Comline and Silence pumps.  Flow rates range from a nominal 65 gph for small reactors up to 2900 gph for closed loops and large systems. Two of these models are DC controllable pumps. Tunze e-jet Tunze’s earliest line of pumps is the e-Jet series. These pumps are multipurpose and may be used as conventional powerheads, in-sump return pumps, or as quick polishing filters. Most notable for use as return pumps are

Reef Tank Tip – Resist The Urge to Submerge

Reef Tank Tip – Resist The Urge to Submerge There are a number of best practices for reefkeeping and one of the bigger ones in my book is to try and minimize the amount of time I put my hands in the tank. I consider myself a perfectionist and when I started to keep reefs I was always looking at my tanks and tinkering with the rocks or corals to achieve a “better” look. I would buy a new coral and spend a lot of time trying to place it just right, moving it from spot to spot. This stressed out the coral and made it tough for it to establish itself in its new environment. What I learned over time is that Mother Nature needs to

Meet the People Who are Rebuilding the Reefs

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

Freshwater Dips and Seahorses

Occasionally a seahorse hobbyist runs into a situation where a freshwater (FW) dip is indicated. A FW Dip can be used as both a therapeutic and a diagnostic tool. As a therapeutic tool it can help rid the seahorse of ectoparasites on the body, in the oral cavity, as well as in the gills. As a diagnostic tool, observation during the dip will give you a good idea if there is a parasitic load or not. It can also be done prophylactically on new arrivals from suspect sources, on wild caught (WC) specimens or when a tank mate has had known parasitic load. We have been doing FW Dips for over 11 years. We have found that every species we have encountered has handled FW Dips just fine

The filtration is a fitersock and cermedia bio balls along with a Reef Octopus bh50 skimmer. Light is dual t5 ho with Trulumen blue led strip. He will be upgrading lighting soon.

Picture of the Week, Green Hammer Coral

Stop, it’s hammer time. Cheesy throwbacks to the 80s aside, the hammer coral is a staple in many reef tanks much like MC Hammer’s song was a permanent fixture in many a Sony Walkman. Getting past all of this nostalgia, hammer corals offer the best of both worlds for corals. On one hand, they have a hard skeleton, but on the other they are adorned with flowy, fleshy tissue that draws in those seeking a little more movement in the water.

Commercially Available Porkfish

Three years ago we posted a blog stating the commercial production potential of Porkfish, Anisotremis virginicus (Porkfish Protocol – Rising Tide’s First Commercial Species). As you’ll recall, researchers at the Tropical Aquaculture Laboratory collected eggs spawned at SeaWorld Orlando and grew them to the juvenile phase and beyond. This was not the first time that Porkfish had been grown in captivity (again credit goes to Martin Moe and company). It was, however, the first time that Porkfish had been grown from eggs spawned in captivity using standard commercial production protocols; including the use of hatchery grown live feeds (rotifers and Artemia). This proved inspiring to one of Rising Tide’s industry partners who decided to add this fish to their list of available species. Figure 2.
