That Fish Blog – Aquarium Advice and Information

That Fish Place – That Pet Place is proud to introduce a new premium salt brand to our line of quality salt water products:  H2Ocean Pro+ Natural Reef Salt from D-D the Aquarium Solution.

Similar to brands like Red Sea Coral Pro, D-D H2Ocean Pro+  is harvested from sea water naturally evaporated with solar energy. What could be more natural than real salt water? After harvesting the salt, the natural product is tweaked a little to provide better results for use in our aquariums. For instance, the calcium and magnesium levels are slightly elevated above natural salt water levels. Why? Well, these two elements are quickly used up in reef aquariums, and because our reef tanks aren’t naturally replenished like the oceans, our inverts rely on us to keep these key elements in check. By slightly elevating the levels of calcium and magnesium, D-D H2Ocean Pro+ allows you to dose less, without getting too far out of sync chemically with their natural salt product. Furthermore, the chloride content is slightly reduced from what we see in natural saltwater. By slightly reducing the chloride content in the bucket, D-D H2Ocean has accounted for the extra chloride that usually comes along with dosing in reef tanks where most supplements utilize calcium and magnesium chloride. This helps make sure the chloride content doesn’t elevate too far beyond natural salt water levels in your reef tank. Just one other fine detail addressed by the chemists at D-D H2Ocean.

When this salt  is mixed to a S.G: of 1.025 @ 25°C = 35.5 ppt, your aquarium water parameters should look like this:

pH  level 8.3, range 8.2-8.4 
dKH level 9.3, range 8.7-9.8 
Calcium (Ca2+) level 440, range 430-460 mg/l
Magnesium (Mg2+) level 1340, range 1300-1380 mg/l
Chloride (Cl-) level 19550, range 19960-20130 mg/l
Potassium (K+) level 410, range 380-420 mg/l

So what makes this salt so good? Well, one thing we know about the ocean is that its parameters are pretty consistent. You’re not going to have one day on the reef where the calcium is 500ppm, and a week later be 400ppm. Its important that in our reef tanks we offer the same type of consistency. And, being that corals are from the ocean, doesn’t it make sense to stay as close to natural saltwater conditions as possible? D-D H2Ocean Pro+ mixes quickly, helping hobbyists get consistent results without having to wait 2-3 days for the salt to thoroughly dissolve. Those of us with sensitive stoney corals can attest to how finicky our corals can be over slight changes in parameters. Even hobbyists running Ultra Low Nutrient Systems have benefited from using D-D H2Ocean Pro+ because of its close-to-natural-saltwater levels. Regardless of what corals you keep, its vital to our reef systems to only deal with manufacturers with great quality control. 

Beyond the parameters, this salt is usually less clumpy, less dusty (not much worse than a salt cloud going right up your nose), and mixes up rather clear.  All and all, its this bloggers opinion that D-D H2Ocean Pro+ is one of the best salts offered at That Fish Place – That Pet Place. We currently offer the salt in the retail store, and it will soon be making it’s online debut.

Choosing the right aquarium salt mix to add to your tank can be can be a confusing process, especially if you’re new to the hobby. But, it isn’t as complicated as it may seem, you just need a little background info to get you on the right path to choosing the salt that is appropriate for your set-up.  

Salt in Freshwater Aquariums

Adding salt to a freshwater aquarium is not a necessity, but it is used by many aquarists as a treatment to add electrolytes to the aquarium water, and as both a stress reducer and a parasite deterrent. Basic Aquarium Salt is not the same as the formulated mixes used to make a brackish or saltwater aquarium. Aquarium Salt is simply Sodium Chloride, and does not contain minerals and trace elements like calcium and iodine like sea water mixes. Adding small portions of this salt can help to treat osmoregulatory stress, an imbalance or disruption in the exchange of salts and minerals between the fish itself and its environment. Stressful situations such as transport, disease, or injury can cause osmoregulatory stress, but if used properly, aquarium salt can increase blood and oxygen flow through the gills, helping the fish relax and heal. When used in higher concentrations for short time periods as a dip or bath, salt can help to build a the protective slime coat on the body, preventing parasites from attaching and even killing one-celled parasites like Protozoa, that may already be on the fish. While aquarium salt does have some benefits, it is not a necessary additive. Once introduced to the tank, salt does not evaporate out of the tank. It can only be removed with water changes and plants, inverts and other sensitive species may be negatively impacted if the concentration is allowed to rise. Read More »

The results are in! We polled aquarium hobbyists like you to find out which style and brand of filter is most popular to maintain a home aquarium. Check out our infographic to see where your favorite filter fits. You can see the full-sized graphic here.

We created a survey a few weeks ago to gather input on what you see as the best aquarium filters are in the hobby today. We received responses to the survey from over 100 aquarists, from beginner level to professional keepers of various sizes and types of aquariums. With the data collected we created a colorful infographic to show you which filters came out on top! Marineland and Fluval Brand filters topped the chart with more than half of the respondents listing these manufacturerers. Canister filters are now the top type of filtration for any aquarium type, with power filters following closely behind.

We’d like to thank all of you who participated in the survey to give us these results. The infographic is also available for use in your own page, just copy and paste the code below:

Gorgonians, also known as Sea Fans or Sea Whips, are beautiful and fascinating creatures found throughout the world’s oceans. These creatures are rather iconic, their branched or net-like structures adding a different dimension to a reef, swaying gently with the current.  Gorgonians are flexible, stationary cnidarians though they are very similar to soft corals. Individual tiny polyps form colonies in a variety of sizes and shapes. Some are stiff and erect, resembling the veins of a leaf, some resemble ribbons with polyps aligned on the edges, others look like plumes or are branched like trees. There are also single strand colonies and those that encrust on rock in thin sheets. They are often brightly coloured, purple, red, orange or yellow, and polyps may be white, brown, yellow or some other pale shade.

About Gorgonians

More than 500 described species of Gorgonian are found tropical and subtropical oceans around the world. More species are found in the tropical Atlantic that in other regions. They usually grow in shallow waters, though there are some species that grow in depths of more than 1000 ft. Shallow water species tend to be more flexible and broad to withstand currents while deeper water types grow tall, thin, and more rigid. They may grow anchored to solid surfaces like rock or coral, or they may “root” in loose gravel or sediment.  Gorgonian colonies are supported by an internal, ridid central skeleton covered with softer tissue that connects each polyp to the next to form the colony. The structure a gorgonian colony creates varies between species from a simple whip-like form to complex net-like fans that can be several feet tall and wide.

Gorgonians provide a secure home to many other maring species including brittle stars, bryozoans and hydrozoans. Pygmy seahorses (Hippocampus bargibanti) cling to several specific species and have adapted to blend perfectly with the colonies with color and texture specic camouflage.  You may also find tiny species of crabs, shrimp, gobies, blennies, and other creatures have also adapted to thrive amongst the polyps and branches of Sea Fans.

Choosing a Gorgonian

It’s important to recognize a healthy gorgonian when you’re ready to put one in your tank. Carefully examine your choices, looking for any signs of damage to the skin. Have the person helping you look gently turn each specimen in the water, so you can get a full look, and take notice of any damage, missing tissue, or flaking or peeling of tissue when the specimen is moving. Smell the water in the holding tank. If there is a noticeable odor, avoid the tank, as it may be sign that one or more of the gorgonians is rotting. Look for one with a thick, sturdy, uncut stem or base, and at least a few extended polyps.

Gorgonian Care

Care of gorgonians will vary greatly according to the species you acquire, and you should take care to research the variety before purchase to ensure that you can provide what it needs to thrive.  That being said, most of the common species available in the trade have relatively simple needs.

When you place your new gorgonian in the tank, give it plenty of space where it can sway with the current, completely submerged and without touching other corals or surfaces. Be sure to orient your Sea Fan in good, strong, direct current to ensure they are exposed to plenty of food when it is added to the tank. The water flow will also provide the tissue with plenty of oxygen and keep the surface free of waste and debris. The specimen should be mounted upright and with plenty of light exposure.

Gorgonians are filter feeders. Each tiny polyp has eight tentacles used to catch phytoplankton and other tiny particles carried to them in the current. Many prefer to feed at night, so generally this is when you’ll see the polyps emerge. There are many commercial invertebrate food options available to offer gorgonians. You may also offer them tiny frozen foods like rotifers, cyclopeeze and baby brine shrimp. Administer a small amount of food to entice the polyps to open, then follow a short while later with a larger dose when the most of the polyps are extended.

Many Gorgonians are also photosynthetic, containing symbiotic algae in their polyps that provide a secondary energy source for the colony. Fro these species it is vital that strong light is provided. Photosynthetis species typically have brown or green polyps as opposed to those lacking pigmentation.  These species may grow rapidly when kept in ideal conditions, and periodic pruning may be required. See this article for detailed info on pruning and propogation.

Be aware before you purchase a gorgonian that many fish and inverts may see them as a new meal. Keep a watchful eye for crabs, snails, slugs and other predators that can quickly damage your fan. Gorgonians also play host to lots of other organisms, so don’t panic right away if you find tiny serpent stars, anemones or other creatures from your tank amongst the branches.

The choices for lighting your aquarium have never been so vast. Whether you are setting up a new aquarium, replacing an old light fixture, or adding to your existing light, there are many decisions to be made.  New technology, and improvements on older lighting methods, provide today’s aquarium hobbyist with a dizzying array of lighting choices for any aquarium. So, how do you choose? What is the best light for your aquarium?

Here are a few questions to ask yourself, to help you with the decision:

Is the light that you are looking for only going to be used on your current aquarium habitat, or are you planning on a more advanced aquarium in the future that may require a higher output light source? You may want to consider a stronger light than you need for your current livestock, as basic lighting may limit what you can keep in the tank down the line.   Read More »
