JBJ 28 Gallon Nano Owners Club

My elegance coral: It has a lovely green/cyan colour with pink tips.

I am so happy with this next coral. It was bought it as completly brown under the LED's and halide it has turned a deep blue/purple on the areas exposed to the light. This coral is located on the side of the tank where the halide is weakest, but LED's are located more of less above it. The photo's dont do this coral any justice. The coral has coloured so well that even out of the water the blue/purple parts look blue/purple.

This is another coral which under the RB LED's is turning a green colour from being all brown.

This coralfrag was a bit browny/green when bought, but colured up nicely after the LED's went in and I started to use GFO: It now has excellent poly extension as well. Its one of m fav frags.

A nice shot showing my ugy clam. It is so drab brown looking, but I bought it as it had been sitting in the LFS for weeks and looked extremely healthy:

Another shot of the plate coral and GSP. The GSP looks awesome under the LED's only and simply glows radioactive neon green:

A nice side shot. Due to the curved design of the tank, taking focused shots of the front is extremely hard even with the best lens on my Nikon DSLR:

Yet another acro that is looking awesome and has nice polyp extention:

And finaly an FTS: Its hard to capture colours and get the exposure correct. The curved glass is realy annoying for photography:

I am battling phosphates that are leaching from the rocks, using GFO in media container has only limited efficiency. I placed had to tank close to the corner in our living room as the wife wouldnt have it any other way and with only one side in view I simply cannot place the GFO reactor on the side.
 
Sahin, you have a nice looking tank. Is there anyway you can give a shot of the hood so I can see your leds? Also, how did you mount the Osmolator? Do you have any pictures of it in action?
 
Hi, I just finished reading this whole thread from the beginning. We got a CF nanocube 28 for Christmas, and it is coming along pretty well.
I have a couple of questions -
One, how do the pumps come out? I can't see the back of the tank (against the wall), but they feel like they are attached somehow. Is there some sort of trick?
Two, are there any alternatives for the CF bulbs? At first glance they look like some sort of propriatery design to JBJ.

The air pump for the stock skimmer is very loud, I addressed that with a simple and crude but effective fix. I built a box from 1/2" MDF 2 inches bigger than the pump in length, width, and height with a hole in the back just big enough to fit the plug through. I ran the plug and air line through the hole and filled the space around the pump with polyfill, making sure the pump was "floating" in the poly fill. The front cover has to be unscrewed to change the air pump setting, but it is MUCH quieter, no louder than the fans on the hood.
 
Finally did some wire organizing. I used the stick back "wire" clamps at Wal-Mart in the Automotive section. I think its a little bag with 8-10 for $1.69.

Does anyone know if the Tunze Osmolator magnet will fit in the first chamber of the 28 Nanocube?

If you mean the rear chambers, ie the sections with the return pumps, then yes, that is where I have the magnets located.

I have used both magnets and located the optical sensor on the left hand side (when facing the tank) and the magnetic failure sensor on the right hand side. The failure sensor is located at a slightly higher level then the optical sensor. This is because the Tunze Osmolator is design to top water for a minimum of 10 seconds. This is a little more than required for this sized tank and instead of restricting the flow I just setup as above and things just work alright.

These are the most powerful magnets I have ever come across so be careful when attached the two sides. They can possibly crack your glass if they come together at force. They are that strong. But you know that unlike the older plastic attachments, your sensors will never budge from thier place.

I use a 10 litre water container and it lasts me about 9 days. Brilliant!

PS I also add two litres of saturated kalk water to the 8 litres so as to keep up my calcium and alk by a little bit each time, this is far better than using full strentgh which will kill the pump after a few months. In any event the pump is very cheap to replace.
 
Awesome information. I will go ahead and order them today. Do the come as a set or are they sold separatly?

I bought the 2010 version of the Tunze Osmolator which came with the new magnet attachments, so I am not sure how many come in the magnet pack, but I think it should come with the two magnets, best check with the LFS or Roger Vitko.
 
skimmer for 28 gallon nano cube jbj cf quad

skimmer for 28 gallon nano cube jbj cf quad

does the CPR SR3 skimmer work with this nano cube without modification and what chamber does it go in the center.how does it perform.also how far should the side chambers be filled with water to the top or halfway.if half way the heater will not be submerged.

please help thanks mike

Thanks, I will check with Roger.

I wonder if you anyone had problems with the screws on the hood rusting out?
I have that problem so I put a little dab of silicone on each one and it seems to help.
 
I just purchased a JBJ 28 tank only with no pumps, tubing, etc. Just basically barebones. Can someone nice and friendly tell me what part's come with it or could I DIY myself?

Thanks for the help!

For the return pumps you can use maxijets either the MJ1200 or MJ900's. I am not sure if two MJ1200 is going to be to much for the overflow to handle. In any event I use 1 return pump and a Vortech.

Lights: your choice really, there are loads of options.

Skimmer: againmany options but Tunze nano is used by many.

If I were you, I'd try and convert it into a sumped tank and build DIY LEDs.

Well, its a start, there are loads of choices/options you can easily find these by skipping thru the threads.
 
Well, I got my osmolator up and running today. I purchased the Tunze magnet and I really like it alot. It was so easy to set up the osmolator this way. Also started adding Kalk today as well for my top off.
 
Mr9iron: How are you running the kalk? I have upped to the dose to using half strength kalk water...its going to kill that little pump one day...but they are cheap to replace. Hoping it will last me a year at least.
