Aquarium project

Hi,
Welcome to the forum.

Please read the first post in any forum entitled how to use this forum.

I'm trying to plan out a controller for a small aquarium and with the large amount of information on the internet it is getting confusing.
To start, I'm planning on controlling
14 3 watt leds on two dimmable channels,
one channel (7 leds) will be used strictly for blue lights and the other channel (7) for the rest of the lights.

Next I'd like to have a thermometer and a fan or two if things get too warm.

I'd like to have an lcd to display light power and temperature.

Having it hook up to wifi for remote monitoring and possibly controlling the lights and fans is a must.
I already have two uno boards and a mega on the way.

Is it better to get a complete wifi shield or a module? Any other input would be greatly appreciated since I'm very new to micro controllers.

Sorry, but spreading your post out in point mode will probably get more readers.
