The Xaqua INOUT is a complete overflow system that can be installed on aquariums that have an external sump filter. With the INOUT there’s no holes in the bottom of the aquarium, eliminating the risk of catastrophic water leakage possible with conventional overflows. Xaqua INOUT is installed with holes drilled in the side or the back of the aquarium, so there’s no partition that robs space from the aquascape, and the tank volume is unaffected. The special construction makes it noiseless and generates a wave effect on the water surface. The new model introduced in 2016 has a larger drain, allowing a maximum pump capacity of 660 gph (2500 L/h). Drain and return hose set available separately. Manufactured in Italy by Xaqua. Distributed by Two Little Fishies, Inc. in North America, South America, Central America, Mexico, Asia, Australia, and South Africa.

Reborn® coarse aragonite media for calcium reactors is composed of fossil skeletons of reef building corals sustainably harvested from pristine sites in the Western Pacific. When dissolved, ReBorn replenishes calcium and carbonate alkalinity, strontium and trace elements. The coarse size of ReBorn allows for unrestricted water flow and easy diffusion of carbon dioxide, for maximum efficiency and easy maintenance of the calcium reactor. ReBorn dissolves completely and will not turn to mush! Packaged in 4 kg (8.8 lb) pouch, 20 kg (44 lb) box, and larger bulk sizes.

ReMag is a magnesium-rich natural stone sized to blend well with ReBorn and other calcium carbonate media for use in calcium reactors. ReMag makes maintaining the magnesium level in your reef a no-brainer. Simply use ReMag in a calcium reactor according to the directions to supply the magnesium your corals need. Aside from saving you time and money, it gives you more reason to enjoy watching your corals grow.

ReVive Coral Cleaner is a revolutionary product developed by Julian Sprung for cleansing live stony and soft corals, zoantharians, and anemones. It is a surface cleaning dip based on plant extracts. Use for all general purpose live coral cleansing, as a part of acclimation to aquariums when corals or anemones are first received, for rinsing prior to shipping, and for rinsing newly fragmented corals, such as at coral farming facilities. Used in public aquariums for cleansing medusae in jellyfish culture labs, and for cleansing cuttlefish eggs. 500 ml (16.8 fl oz) bottle.

Two Little Fishies' NanoMag is an itsy-bitsy, lean, high-energy, window-cleaning apparatus. Its patented design provides flexibility and a slender profile that slips safely between polyps or plants and viewing windows. It’s got the umph needed for cleaning glass up to 1/2” thick. The NanoMag also glides across the curved surfaces of fish bowls, wiping off algal films with ease, and it’s so much fun to use you just might have to take turns.

Two Little Fishies BettaMag is an even smaller window-cleaning apparatus than NanoMag, designed for use on Betta and Goldfish bowls or Pico aquariums. In small bowls or Pico aquariums the NanoMag is so strong it actually moves the whole tank when you try to clean the windows! BettaMag solves that problem by being sized just right. It’s ideal for glass with a thickness of 1/8 to 1/4 inch. Patented design by Julian Sprung.

A complete assembled replacement part for the square magnetically-coupled scrubber of NanoMag.

The MagFox uses magnetic attraction to propel a small brush inside aquarium hoses and pipes, allowing it to clean away algae and other deposits that block the water flow. Patent pending design by Julian Sprung.

MagFox Replacement inner part.

The VeggieMag uses magnetic attraction instead of a suction cup to hold our SeaVeggies clip in place for windows up to 3/4” thick! It’s easy to position at any level in the aquarium, and easy to retrieve it without getting your hands wet. As an added feature the VeggieMag floats! Patented design by Julian Sprung.

Although our VeggieMag is designed to work on windows up to 3/4” thick when feeding normal-sized fish, big Angelfish, Naso Tangs, Triggerfish or Harlequin wrasse, among other voracious muscular beasts, can defeat its magnetic coupling. They even take great pleasure in running at it and yanking it off the wall. Well now we have a response to this behavor: MegaVeggieMag, which uses a 1” diameter x 1” long ultra high strength Neodymium magnet. That will keep the clip in place. Watch the surprise in your big fishes’ eyes as they try but can’t yank the clip off. Be sure to fold the SeaVeggies sheet so that it forms a thick layer that stays in the clip jaws. Patented design by Julian Sprung.

Our NEW feeding device, MagFeeder and its accessories make feeding your fishes more effective and enjoyable. MagFeeder comes with a floating feed ring that retains flakefoods, pellets, powdered invertebrate feeds, or any food you want to dose into your tank but don’t want to see go right over the overflow. The magnetic coupling makes it posible to easily position the ring without getting your hands wet, and the jointed connection assembly makes it simple to adjust the distance from the aquarium wall. Another feature, the Two Little Fishies button pops into the mushroom head of the feeder. It retains any ring-shaped foods, such as the Grazer™ from New Era. The magnetic coupling lets you position or retrieve MagFeeder easily, and without getting your hands wet. Patented design by Julian Sprung.

The NEW PouchFeeder comes complete with magnetically coupled wall attachment parts just like VeggieMag and MagFeeder. Use the perforated pouch to serve cubes or blocks of frozen foods, folded sheets of seaweed, or our SeaVeggies Red Seaweed whole plants. Watch your marine and freshwater fishes (or invertebrates) graze from the pouch! Spare pouches also available.

CorAffix is an ethyl cyanoacrylate bonding compound with viscosity similar to honey. Use it for attaching stony corals, gorgonians, and other sessile invertebrates in natural positions on the live rock in aquariums. Also for attaching coral “frags” in coral culturing. Use with AquaStik™ to attach larger coral heads. First put freshly mixed AquaStik on live rock. Push the coral base into the AquaStik and then remove the coral, leaving the impression of the coral base in the AquaStik left in place on the live rock. Allow the AquaStik to harden for 20 minutes. Next put CorAffix on the coral base and press it into the impression made in the AquaStik, forming a secure bond in 20 seconds. Available in a 2 oz bottle with a convenient pin cap to prevent the tip from clogging. 56.7g (2oz)

The PhosBan Reactor 150 is designed with the upflow principle to achieve the most efficient use of PhosBan® or other chemical filter media. By pushing water from the bottom upward through a dispersion plate, it forces an even distribution of water through the media, and prevents channeling. It can be mounted hanging on the back of the aquarium or below the aquarium. Hose barb connections are for 1/2 inch i.d. tubing. Includes 1/2 inch barbed ball valve for flow control, and hose clamps. Use with any pump having a capacity between 100 and 250 gph, but regulate the flow rate to the recommended 20 to 30 gallons per hour with the included ball valve.

NPX Bioplastics® granular media made from biodegradable polymers. For use in a fluidized reactor. The slow release of organic food from these plastics promotes the development of bacteria that assimilate nitrate and phosphate. These bacteria can be harvested by protein skimmers, so that the nitrate and phosphate levels are naturally reduced. The bacteria are also a food source for filter-feeding invertebrates such as corals, clams, sponges, and feather dusters.

Use with Bactiv8 NPX to promote rapid assimilation of nitrate in saltwater aquariums.

Do you think it’s important to maintain salinity precisely? We’re with you. That’s why we created AccuraSea Seawater Reference Solution, the only calibration solution of its kind made from real seawater. It’s pure natural sea water micron filtered and UV sterilized then adjusted with reverse osmosis water to the standard S = 35 or conductivity of 53 mS/cm at 25°C (77°F). Use it to accurately calibrate seawater refractometers and check the accuracy of swing-arm hydrometers. You may also want to use it as a reference for test kits used to measure the concentrations of various seawater components, since it is natural seawater with the correct and well-known concentrations of all dissolved salts. Packaged in 250 ml bottles.
