JBJ Lighting

The ultimate reef series biotope!
JBJ launches its MEGA powered 28g Nano-Cube HQI-Reef Series. The new 2007 model incorporates many high-tech features not commonly found in "All-In-One" systems.

The new concept behind the 28g Nano-Cube HQI was inspired by hundreds of reef hobbyists who requested higher powered lighting, protein skimming, increased water circulation, a more simplified filter, storage area in the stand for chillers, and designated water level columns in the rear chambers for heaters, refugiums and protein skimmers.

Our challenge was to offer these key features while still keeping the aesthetic appeal and contemporary look of an integrated canopy and allowing for future mod ability. The 28g Nano-Cube HQI-Reef Series is truly the evolution of years of experience since the original Nano-Cube Aquarium, which launched the small "All-In-One" tank market just 4 years ago.

  • (1) 150W HQI/14K
  • (4) Nite-Vu LEDs with Separate Power cord
  • (2) UL-Listed Accela Powerheads (266gph each/16W each)
  • (2) Directional flow nozzles on each side of the aquarium
  • (1) Ocean Pulse Duo—Alternating WaveMaker
  • (1) Integrated center overflow
  • (1) Newly redesigned filtration system with designated heater column with constant water levels
  • (4) Integrated cooling fans (3000rpm`s)
  • (1) Flame retardant ABS canopy housing
  • (1) Integrated thermal protector for canopy (auto shut off protection)
  • (1) Removal filter media basket with handle and sliding door for easy access
  • (1) Filter media—sponge, activated carbon, ceramic rings
Mega Illumination
We are proud to offer the most intense illumination system out of the box, boasting a whopping 5.35W of power per gallon. combined with our new German Parabolic Reflector, it casts sparkling shimmering rays from every corner of the aquarium. Definitely the choice for hobbyists who intend to keep hard corals, sps and clams. The 28g Nano Cube HQI comes equipped with (1) 150W Double Ended HQI/14K for daytime photo periods and (4) Nite-Vu LEDs for nocturnal photo periods. Nite-Vu LEDs are offered with its` own individual power cord for timer usage.

Nite-Vu LEDs are strategically placed on all four corners to evenly distribute moon lighting throughout the aquarium. All LEDs are pre-wired individually with its` own male plug for easy replacement. Consumes less than 1W of power, but strong enough to illuminate nocturnal behaviors.

Stay Cool
The secret to our running canopy is our artistic canopy which also serves as a key factor in heat dissipation. All canopies are made from Flame Retardant ABS Plastic. The 4 cooling fans are paired on 2 separate circuits in case one set of fans were to ever lose performance or fail. We`ve even gone one step further as a safety feature and added a thermal protector into the canopy. In the event all fans fail... the thermal protector will automatically shut off the HQI lighting until temperatures reach safe conditions from the excess heat.

Easy Feeding
New feeding lid is lighter than the previous full front lid. Grants quick and easy access for feeding and retrieving water samples without lifting the entire hood.

Note: New HQI Canopy and Ballast will be offered as an upgrade lighting kit for existing 24g Nano Cube Deluxe Owners.

Smart Filtration
Our newly redesigned filter starts as water enters the center overflow. The water is directed into out new 3-Stage filter media basket, which comes installed with a mechanical sponge, chemical activated carbon and biological ceramic rings.

Our unique 3-Stage filter media basket can host a variety of chemical medias to suit your needs. Cleaning is especially easy since all you have to do is lift up on the basket handle and watch the water drain out the bottom for a simple and dry filter change. All baskets have a sliding door for added convenience.

Once the water leaves the filter basket water is split to the designated heater column to the left and the protein skimmer chamber to the right. Please note that the heater, protein skimmer chamber and 3-Stage Filter media basket always has a constant water level. You can easily customize other auxiliary equipment to your aquarium without worrying about water levels in the rear compartment fluctuating. no more broken heaters or heaters that automatically shut off due to evaporation and low water levels.

Once the water is heated and skimmed, the water overflows into the pump water columns. Both pump columns are shared increasing the water volume for long weekends. Water is directed back into the main body of the aquarium via (2) Accela Pumps rated at 266gph at a low energy draw of 16W. Your Nano Cube HQI includes our new Ocean Pulse Duo Wavemaker which creates turbulent currents for a more natural reef environment. Your wavemaker can be set from 10 seconds to 6 minute alternating cycles. Water is returned via (2) directional return nozzles on each side of the center overflow for even natural currents.

Same Integrated Canopy Appeal
The new 28g Nano Cube HQI offers 3.5" more depth than the previous 24g Nano Cube Deluxe. This larger aquarium grants more space for live rock, corals and fish. We made sure to keep the stylish appearance of an "All-In-One" unit while providing open access into the newly expanded rear filtration compartments. This revolutionary design grants easy access for modifications without the constant hassle of drilling, cutting and working within space constraints due to the canopy.

Rear Filtration Access
The rear filtration area is open and grants full access without opening the canopy. This unique baffle design naturally keeps water temperatures more stable through natural evaporation. Chiller inlet and outlet tubes can be fitted easily without the need to cut holes into the rear of the canopy.

Stand Tall
The perfect compliment to exhibit your reef aquarium. Our new design stand at 32" high for better viewing. The cabinet stand is offered with (2) removable shelves and is designed to fit a small chiller inside without reducing the air flow required by chillers.

Easy Assembly
All stands are very sturdy and simple to assemble. No more cam locks and bolts to mess with.

JBJ 28-gal. Professional (Adva

This is a excellent system. Includes everything except heater & skimmer. Lights cycle through daytime/dusk-dawn/night perfectly; unit is extremely quiet; wave maker operates perfectly. My unit included the stand. Corals are growing very well! I would not have any other Biocube. I found JBJ's customer service to be knowledgeable, courteous, professional & efficient. My corals, fish, inverts & I adore this unit. I would NOT buy the lower-end model; ONLY the advanced model.

JBJ Nano Cube Impressions

Previously had a 75 gallon reef and wanted to get back into things but without going all out. After quite a bit of looking around and research, settled on the JBJ Nano Cube 28. I originally intended to buy the advanced but ended up going with the lower cost CF unit instead (I plan to replace the CF bulbs with a new set from Steve's LEDs). Light from CF bulbs is pretty good and would certainly be sufficient for fish and easy corals. In my 72-73F house, the tank ran around 80-81F with the CF bulbs on ~12 hours a day. I tossed the included filter basket and purchased the greatly enhanced (and much larger) one from In Tank media baskets. All in all, very happy with the tank - was well protected for shipping. Looks nice as well. The included pumps and fans make some noise - nothing terrible, but you probably wouldn't be happy with them in a bedroom. There are plenty of threads on replacing the stock pumps if you so choose.

Poor design, worse cust. serv.

The tank looks nice when set up but has lots of flaws. There is only one plug for the night and day lights so you have to manually turn them on and off. It defeats the purpose of having a surge protector with a timer built in. Lid does not fit tight and they dont offer enough access points into the back reservoirs. The cooling fans are loud. Also the tank starting leaking after 8 months. This leads to the worst part: JBJ Customer Service. You would think that since the leak was caused by a defect in their product they would claim responsibility and overnight a new tank so you can get it set up and running. No! Dont even waste your time calling the number on the website. No one answers. Instead you are put into an automated loop were you cant leave a message because the box is full. Second it took them 2 days to respond after i sent my email. Then i was shocked to here they would not overnight the tank. I could pick up the expensive tab if i wanted to but that is there policy. You cant find this policy anywhere on their website. When asked to talk to a manager (through email...still cant get them on the phone) the customer service person refuses. So my $300 plus dollars worth of livestock started to die. I tried to make a temporary home in a five gallon bucket but the stress was too much. JBJ doesnt care. You're better off buying a different aquarium - better yet, an aquarium from a DIFFERENT COMPANY!

Great all in one tank

Great tank. Recommend a ATO for water evaporation a small fan to keep it cool. Power compacs run hot. I have mine with the in tank media basket upgrade, aquamax HOB skimmer, tunze ATO (the small $103 one),and tunze aquawind fan (slightly modified).

Pretty Good System

Lights are good and have a good look to them. The filter system needs some work. We had to add a skimmer and we decided to get the UV for the system as well. The ammount of ceramic rings for the biofiltration seems a light side. I feel like there should be some more rings to get enough surface area for the filtration. So depending on how long the cycle takes on the tank we may be adding some more rings to the filter. The return flow also doesnt seem to have enough velocity too it to produce a good current and sweep the detritus off the rockwork/ sand and future corals. We are most likely going to have to add a powerhead or two to have enough flow. Although with the wavemaker we could run the powerheads off the wavemaker in paralell with the return pumps and then get some good movement that way. All in all I think the system is good and only requires a few tweaks here and there to be great. But if it came perfect out of the box 1 nobody would be able to afford it and 2 it just wouldnt be as much fun if there wasnt stuff to mess with and modify.

Great Aquarium

I really enjoy the JBJ 28 gal. the lights are great. I couldn't believe how bright they actually were. I am very pleased with my decision to purchase. I have even now ordered a Coralife HQI 150W for my Biocube. I wish I had first came to you to purchase the JBJ 6 months ago when I bought the BioCube. Now I would have two JBJ's instead of one of each. Thanks again, Terry S jones

Decent All-In-One System

I purchased the system with the metal halide lighting. First thing you need to now about this system is that all the stock pumps,the protein skimmer, media basket with media including the the foam chamber pads are ok. The 2 stock pumps are woefully inadequate and cannot do a proper job of circulating the water especially if you are keeping corals. Also buy the Tunze 9002 nano skimmer. I have read in a few of the comments that people felt for that the Tunze skimmer felt "flimsy" or cheap. I would have to disagree. The plastic is the same plastic material they use in their wavemakers and holds up well. . Yes, you WILL have to cut off the magnet on the Tunze skimmer to get it to fit into the central compartment in the back, but its a perfect fit. Also, you will need to replace the skimmer cup that comes with the Tunze skimmer because it does not seat right and will not go all the way down. Scroll down a few posts and go to the link someone had suggested, mediabaskets.com, and get yourself the small rectangle collection cup for the Tunze 9002. Fits perfectly. Also, there is enough room to fit 2 Marineland Penguin 100 water filters on the back, one on the left side and one on the right, both fit perfectly well in the same chambers the water return pumps are. Remember to remove the bio-wheels off those pumps for they are nitrate factories and you dont want that. There is no such thing as over-filtration.
