DIY LED questions
 

Ok its time to replace my PC bulbs again in my 29G Biocube... They are never cheap so I think its time to upgrade to LED's. With the birth of my baby girl and needing to buy a house I can't afford to buy a $600 LED fixture and a $1000 aquarium controller to drive it :)

I have been on Rapid LED's website and they make a retrofit kit to setup me up with LEDs, fans, drivers, wiring, ect. but it requires a controller or a dimmable driver... I would prefer a controller with an auto top off function (since my Tunze just crapped out) and maybe a few other functions but I am not looking for every bell and whistle. What are my options?

Neptune Jr + RapidLED Retrofit is a great solution.

I am very very happy with mine :mrgreen:

Do you need a controller with those LEDs? Couldn't you just put them on a timer for on/off cycle? No bells and whistles there :-)

What all is required to connect the Apex Jr to the LED's? Did you get the pwm version or the 1-10V analog?

I just noticed that the non-dimmable version mentions no controller and the dimmable version requires controller and 10V adaptor. So my next question is with the dimmable can you modify the colour/brightness? Will the Apex Jr allow sunrise/sunset?

apex jr controller $230, apex vdm module $105

the vdm module has 4 variable outputs that use 0-10vdc. ie; you could control 2 or 3 led drivers and a tunze pump.

Yes you can create fading sunrise and sunset by defining a 'ramp profile' in the apex web interface. It uses a scripting language to define the logic of each port or outlet, it's really fun.

It all adds up, but at the end of the day a controller is a really nice luxury to have. Temp control (can do seasonal tables), feeding mode, ato, data logging, and one and on it goes.

Ya, I LOVE my Apex!! And you can log in remotely, I can access via my phone in town, or when I'm in camp and check temps etc, It also emails alarms and txt them to you

How does it compare to the Reef Keeper Lite?

Personally I don't think they are in the same league to compare.

There is also a major update being released for all apex controllers, which was announced at MACNA -- http://reefbuilders.com/2013/08/30/a...g-integration/

Based on your cost I recommend:

I bought StevesLEDs for my 30 Gallon setup and they are top notch quality .

This package will give you an option to do it all from scratch yourself - if you are up to the work or pay $80 extra and have all the hard work done for you. I built my own from scratch and if I wouldn't do it again - was just a pain in my ass haha. Depends on how much work you are willing to do...

This system doesn't require a controller - comes with potentiometer for adjustments which is all I use.

However if you want your controller for doing ATO stuff then I don't have much of a recommendation as I have't tried one yet. I basically went the the highest quality LED route while trying to save as much money as possible so I haven't done ATO.

Something for a controller - if I was to buy one - I'd get Reef Angel: http://www.reefangel.com/order.aspx

I like it because I am a computer guy and can program it to do whatever I want and it's expandable to do anything you want. So you can start cheap and eventually expand it to be expensive / extensive.
