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

Aquarium Technologies Borrowed from Other Industries

Actinic lighting was developed and used in other industries before reef aquariumsWe marine aquarists use a variety of tools to help keep our tanks healthy by either changing or removing the waste products of the animals we keep. But did you know virtually all of the devices we use were originally designed for other industries? OzoneFor instance, ozone is a naturally forming gas found in our atmosphere that helps protect us from the damaging effects of the sun’s ultraviolet radiation. It was discovered in 1839 by Christian Friedrich Schönbein. Ozone was originally used to purify drinking water and as a health-giving gas. Unfortunately, that health idea produced just the opposite result because the oxidizing effect we can use to purify certain things will also oxidize us, especially our lungs.

Incredible Tank With Hidden DSB

Today we would like show you a very interesting marine aquarium; it is a very well made cabinet-tank system with a special feature: the hidden deep sand bed (DSB) beneath it. This system was designed and built by Italian company Crystal Reef, and we first saw it...

Need Help from Fellow Hobbyists? Don’t Spare the Details!

Before hitting the “help button,” make sure you’ve gathered all the relevant information about your systemWe’ve all been there at one time or another: A major problem arises that’s causing livestock losses—and/or loss of sanity—and we need advice from local fish store staffers, the members of our favorite forum, website moderators, or just friendly local hobbyists on how to find a workable solution. However, when we’re desperate to resolve a problem, we sometimes pose questions in a manner that’s, well, a bit counterproductive. In many cases, the question is worded something like this: “My fish/corals keep dying one after another. It seems like every day I lose one or two more. I don’t see any signs of disease, and all my water parameters are perfect. What could be the problem? Can you recommend a product or medication that will put a stop to this? Please help, as I’m about to quit this hobby in disgust!”While this question conveys a great deal of passion, what it lacks is virtually every pertinent detail that could aid in finding a solution.

The Trials & Tribulations of a Young Reef Tank

Starting and maintaining a successful reef tank is not an easy task, even for veterans of the hobby. There are many curveballs out there capable of bringing a reef keeper to their knees that can cause them to “cry uncle”, especially during the early part of a tank’s life. For my latest tank I encountered a few bumps in the road, forcing me to endure what I would term a rough start. Now mind you, I have been in the hobby for over 20 years so the knowledge I accrued has certainly made it easier for me to steer clear of past problems. For instance, in an old tank I had a wicked type of invasive algae that hitchhiked in on some live rock, forcing me to shut
