Ok this is the second project where EZB will be used to control lighting , current flow , temp , salinity ect. This thread will show just about every step ot the build , electronics , wiring and eventually the scripts to make it work.

Well, Ive been at a standstill on this guy for months due to parts issues and time constraints. Got the parts, got the...
I purchased them on ebay , search 10w led. When I do this again I will use a much larger heat sink.
Two quotes from Thomas Edison inspired me today
"To invent, you need a good imagination and a pile of junk."
"A genius is often merely a talented person who has done all of his or her homework."
Ok after finding a way Not to light the tank lol , I tried agian with some lower power. Im not sure of total output but these are not producing the crazy heat the last ones were. I estimate about 12 watts total output.
Whats nice is that because the light is very intense and originating from a small point the light shimmers on the bed of the tank just like in the ocean or a pool on a bright sunny day.
The case I made I will still use. It will house uv leds and blue leds. The. Uv are night lighting and blue will give the tank a actinic ocean look. The white leds pictured , blue leds and uv night light will all be controlled by ezb
I already ordered the ezb for this project but due to timing it may be delayed by chinese holidays.
So I descided to start making my own zero water. Thats water that is filtered from organic contaminates , chlorine , and heavy metal. These are things that build up and settle in fish tanks and also increase corrosion on electric equipment in proximity to contaminated water that is evaporating. Here is a before and after test with a parts per million water tester...
072 PPM BEFORE water treatment
000 PPM After the water treatmentI am using a pitcher type filter at the moment to try out this ionic exchange filter element. If this works well then I will use a couple small pumps so ezb can control scheduled water changes to make the least impact to the Marine environment.
The fish appreciate the new lighting and have left their hiding places to look for food. This is a good sign they are okay with the lighting and not stressed out.I added more rock and moved in additional marine life. A pencil sea urchin , red king damsel, two percula clown fish, horse shoe crab , spotted green puffer fish, long tentacle pink tip anemone.
The small white leds are ok but I need to get the large light back working. Im planning on dropping the voltage down to 10.1 volts instead of 12 volts to bring heat to a manageable temperature and adding two 40mm fans since the first one kicked the bucket. I will use a buck step down converter to drop the voltage to the ten volts. One led is damaged but if this tests well I will just buy a replacement and swap it out. No big deal as the single color ten watts are about 8 bucks.
More rock , I think the anemone ate something while I was down stairs lol , well it happens.
