Altering From a Freshwater to Saltwater Aquarium

Many people with freshwater aquariums have considered altering their tanks proper right into a saltwater fish or a coral reef tank, nevertheless have heard that it is robust to do, that you will have to pay money for all new instruments and that it may worth some large money. Most frequently, this isn’t so. When you’ve a functioning freshwater aquarium system you may already have lots of the instruments required to make the conversion to a implausible saltwater aquarium system. Let’s shortly bear the objects of equipment that you’re going to need to start your new saltwater aquarium system.

The Aquarium Itself

Clearly, in case you’re altering from a freshwater aquarium to a saltwater aquarium, you already have an aquarium. Is it glass or acrylic? It will not truly matter, as long as it holds water with out leaking. The size of the aquarium does matter, though. For primarily essentially the most half (there are exceptions) the larger the aquarium for a saltwater aquarium, the upper. With a smaller (10 gallon or a lot much less) aquarium, when a problem comes up, points can worsen in a rush as there could also be little “buffer room” for errors and points. Factors corresponding to dangerously extreme ammonia all through biking should be mounted rapidly.

One issue that many freshwater aquarists don’t initially understand is that you just merely can’t put as many saltwater fish in a certain sized tank as you could a freshwater tank. The freshwater “rule of thumb” for the number of fish in a tank is 1″ of grownup physique dimension fish per gallon of tank water. The saltwater “rule of thumb” is 1″ of fish for every 5 gallons of tank water.

Substrate

Most freshwater aquariums use gravel for the substrate. In saltwater aquariums, sand or crushed coral is used for the substrate. Whereas gravel will work in a saltwater aquarium for a portion of the natural filter mattress, aquarium sand or crushed coral works greater for the various critters (i.e. sand sifting fish and invertebrates) which will occupy the reef tank. Crushed coral or totally different calcium-containing substrates might even help stabilize the water prime quality.

Filters and Filtration

Gallon for gallon, saltwater aquariums require additional filtration than freshwater aquariums. For primarily essentially the most half, saltwater critters need greater water prime quality than freshwater critters. Fortunately, it isn’t robust to increase a freshwater aquarium’s filtration to satisfy saltwater aquarium requirements. In case your freshwater tank has a single maintain on tank (H.O.T.) filter, merely add one different one to double the potential. For primarily essentially the most half, the H.O.T. filter solely provides mechanical filtration, eradicating suspended meals particles and totally different particles from the water. In saltwater aquariums, the dwell rock that almost all saltwater aquarists arrange of their tanks provides a majority of the natural filtration platform.

Canister filters work pretty properly in saltwater aquariums. They provide adequate filtration flexibility to allow the aquarist in order so as to add or subtract completely totally different filtration decisions (mechanical, chemical and natural) by altering the media inside the baskets all through the canister to swimsuit their desires.

Beneath Gravel Filters (U.G.F.’s), which are nonetheless utilized in lots of freshwater (and even saltwater) aquarium setups are thought-about an element of the earlier, apart from certain features, corresponding to applications requiring low water circulation. U.G.F.’s require pretty somewhat little bit of maintenance with a view to protect them clear and free of nitrate producing tank provides corresponding to uneaten meals and detritus.

Pumps and Powerheads

Most freshwater aquariums do not take advantage of powerheads or pumps to create a surge or wave influence, nevertheless nearly all pumps and powerheads utilized in aquariums are applicable in each up to date or saltwater.

Lights and Lighting

The lights used on an FW tank are sometimes regular or NO (Common Output) fluorescent bulbs, which is ready to work efficient for a fish-only or fish-only-with-live-rock saltwater tank. Nonetheless, you may ponder together with an actinic blue bulb alongside one among many regular tubes, or change over to 50/50s, as these type of fluorescent bulbs enormously enhance the seen look of the tank and the colors of the fishes.

In the event you’re planning to have a reef tank, you may want to enhance your freshwater lighting to accommodate corals and one other invertebrates corresponding to anemones that require a greater prime quality light in the perfect spectrum fluctuate. The beautiful present creation of L.E.D. lighting for aquariums has made high-quality reef tank lighting not solely attainable however as well as cost-effective (low vitality consumption and 50,000-hour bulb life).

Totally different issues are the material from which the sunshine hood is made, which cannot preserve as a lot because the corrosive outcomes of SW, and in case you want to enhance to VHO, PC, or MH lighting, the standard aquarium hood will not preserve these bulbs. In the event you’re planning a reef system, lighting turns into moderately extra essential and dear. Spend some time researching your potential lighting desires sooner than working all the best way right down to your LFS and laying out a wide range of your hard-earned cash. It has been our experience that the everyday salesperson working in an LFS wouldn’t have a clue to what the lighting requirements are for a reef system, which regularly results in you ending up with each inadequate or pointless instruments.

Aquarium Heaters

Possibly the heater(s) getting used is not going to must be modified, merely make sure this instruments is rated as safe for use in saltwater, notably under-gravel cable form fashions which may be usually utilized in freshwater plant aquariums.

Decorations

Excluding huge stones or rocks, most freshwater tank decorations are ineffective in saltwater aquariums, and some devices corresponding to plastic crops might even be dangerous to marine life. Most marine fish are “grazers” and have a tendency to nibble on each little factor, and it might not take too many eaten fragments of plastic to utterly shut down a fish’s digestive tract. As far as devices like castles, effervescent divers, and sunken chests, in case you’re a “true” saltwater naturalist, together with these type of points is outstanding. Relevant kinds of decorative rocks and corals, each non-living or synthetic, are usually used for adorning saltwater tanks in case you’re not planning on together with dwell rock and/or defending a coral reef system.

All in all, conversion from a freshwater to a saltwater tank just isn’t all that tough. In truth, the most important distinction is the need so as to add sea salt to the water to create a marine environment. Further devices wished aside from the ocean salt could be a hydrometer to measure the salinity, water check out kits, saltwater aquarium books, and a few totally different gives, nevertheless by with the flexibility to make use of “some” of the instruments you already have, you’re off to a reasonably good start.
