nagytamas's 5G nano

[nagytamas]

After shuting down my 30G reeftank, I've kept some of my favourite frags and put them into the 5G quarantine tank.

 

Technical specs:

Lighting: Ledlamp, 15 watt

Circulation: one tunze nano pump, modded

Livestock: corals from my old nano

Filtration: only LR

The led lamp in test mode now. I built it from 4 sq1 rebel coldwhite and 4 royalblue leds with a 350 mA buckpack and 2 P4 processor coolers without fans.

 

And the pics:

Today I reaquascaped the tank, and made some mods on the tunze powerheads, now the produce enough flow.

Last week I went to the lfs and couldn't resist to buy a new fish. The chosen one is a tailspot blenny, one of my favourites. He stays under the biggest rock behind the xenia forest allday. He is a shy guy, but eats everything.

how did you mod the pumps?

Nice tank!

[nagytamas]

how did you mod the pumps?

I removed the flow control tube, and cut out the propeller like flow limiters. This mod doubles the output of this pumps, and after the mod two produce enough flow in my nano. You can see it in this pic after the mod:

Let me introduce my new homemade led driver. The FET based circuit powered with an ATX power supply, and able to drive 3 high power leds. The power loss is 1.5 watt, when 3 rebel leds are driven with 700mA, it means 78% efficiency. Here are the shematics (i built the middle one, with irf540 and bat46 diode):

 

The driver under testing:

I've just finished the tests, and the water parameters better then expected in a filterless two weeks old system:

 

Mg: 1270 mg/L

Ca: 400 mg/L

Alk: 7 nk

NO3: 5 mg/L

NO2: 0 mg/L

NH4: 0mg/L

salinity: 1,026

temperature: 25C

Very nice tank! I'm still amazing at how such small tanks look so huge in pictures, lol.
