An Ultra-Low-Nutrient System for Acropora and other SPS

Top down shot of Acropora microladosWelcome to the next level of coral care. By now I am assuming you have at least understood all the key general practices to maintain some of the hardier corals, from soft corals to large-polyp stony (LPS) corals to some of the more rugged small-polyp stony (SPS) corals. Each category of livestock can be classified into various requirements for the piece of ocean environment you are trying to simulate. Oftentimes we tend to generalize that all parts of the ocean are the same, but as you become educated about the livestock you are trying to maintain, you will understand that there is no single recipe to make everything thrive and flourish in the same tank.Review time So let us review some of the key attributes we, as responsible hobbyists and nature fans, must familiarize ourselves with in order to provide a sustainable environment. The most common aquarium parameters are the following: 1. Tank dimensions Volume (amount of salt water for stability) Depth (impacts light penetration and available environmental zones) Size (impacts aquascaping, flow, lighting choices, growth) 2. Lighting Type: metal halide, T5, LED, or hybrids Spectrum (10,000 to 20,000 Kelvin) Intensity (lux) Photosynthetically Active Radiation (PAR) Photosynthetically Usable Radiation (PUR) Photoperiod (hours) 3.

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

Reader Review: The Avant-Garde Marine Aquarist

Paul B at his recent book release partySpecial thanks to Patrick Sugent for taking the time to write and submit the following review of Paul “Paul B” Baldassano’s The Avant-Garde Marine Aquarist: A 60-Year History of Fishkeeping. We couldn’t have said it better ourselves!“I first came across The Avant-Garde Marine Aquarist in an online forum which Paul Baldassano frequents. I gave the book a read not really quite sure what to expect. You see, I knew Paul has a great deal of saltwater knowledge as well as a witty style in online forums, but I also know that he is on a very different level than me in terms of saltwater aquarium experience. He’s got a tank that is going on 45 years old, and I have a tank that is going on two years old, slightly less old than my twin children. He’s also a big DIY (Do-It-Yourself) person when it comes to saltwater aquariums, and I once hired a professional electrician to change a lightbulb (a sad but true story). So, I thought there was a lot of room for this to be a book that was really beyond my grasp and understanding and just generally over my head with lots of discussion about history I don’t know about, devices I don’t understand, and saltwater theory I can’t follow. Fortunately, that turned out not to be remotely true.

The Best Beginner Small-Polyp Stony Corals

These SPS coral species are a beginner’s best betUpon entering the world of small polyp stony corals (or SPS), many people ask the magic question, “Which types are best for beginners?” In my opinion the most beginner-friendly choices are found in the genera Montipora, Pocillopora, Seriatopora, and Stylophora. Most of the corals I’ll discuss here are commonly available, so there should be a low cost of entry. They’ve also proven fairly hardy in my experience and can be kept in a wider range of parameters than most SPS corals. What’s more, they’re rarely susceptible to the dreaded rapid or slow tissue necrosis (RTN/STN) that you see in Acropora species. General requirements for these SPS coralsCare level: moderate Temperament: peaceful (will not try to attack neighboring corals but will most likely lose to aggressive species) Lighting: moderate to high (of the correct full spectrum) Flow: medium to high Temperature: 72-78F Alkalinity: 8-12 dKH pH: 8.1-8.4 Specific gravity: 1.023-1.025 Preparing for SPS The ultimate practice for these corals is mastering water parameter stability. Don’t chase specific numbers, but if you can keep parameters in the required ranges and stable with very little variance and spikes, you can keep practically any coral. The only other specifics to each coral are placement, which impacts lighting; flow requirements; and whether they need to be fed. These are primarily photosynthetic corals, but additions of amino acids and other elements may help with coloration and growth

Reliable Marine Aquarium Reference Sources

Crack open any of these great saltwater and reef aquarium resource books and be prepared to learn!“Research the characteristics and care requirements of any fish or invertebrate you plan to keep.”“Studying the fundamentals of saltwater aquarium keeping before setting up your first system is a hallmark of success.” We’ve dispensed advice like this time and time again here at Saltwater Smarts. But knowing that you should do research before buying livestock or attempting new techniques is only half the equation. The other half is knowing which sources you can turn to for reliable, authoritative information. After all, there’s a lot of literature floating around out there and not all of it is equally accurate or trustworthy. So, in today’s post, Caribbean Chris and I would like to begin a list of marine aquarium reference sources that we consider valuable, if not indispensable, to hobbyists who are hungry for reliable, time-tested guidance. Under each listing, we’ll explain why we consider the work so valuable to the hobby.
