To give you a real example of a where Jayfish is used, I am posting pictures of my two tanks.  The tank on the left is a 33 Gallon cube and the tank on the right is a 75 Gallon tank.  My aquarium are saltwater based, I do have a small Beta tank but it’s not featured here.  Since I am on the DIY side of things, I have hand built everything you see here.  The tanks are the only think I did not make personally.  Both tanks are drilled, and overflow into my hidden sump under the main tank.  The water is all ONE body, and not separated.  The blue tub is my ATO, I have a small micro DC 12v pump in there that keeps topping up my tank.

In both tanks I have built my own LED units, they are PWM based and are all driven by Meanwell LDD units. My main tank display is a 72 x 1w LED matrix with mixed blue,white,red,green … all levels are independently controlled via the Jayfish PWM LDD light system using the PCA9685 i2c module.  Something I love about Jayfish is it’s ability to help manage complex LED setups, if you do not want to do graduated lighting and prefer simple on/off functionality it’s up to you … Some have even just used on/off and only have one moon light LED that is gradually controlled for sunrise and sunset.

I was sick and tired of doing water changes, hurting my back carrying 5 Gallon buckets with one and and so on.  So i drilled a drainage hole and a water return hole through my house wall.  This external box with a tank in it, handles my premixing and ready to go water change.  I have a temperature sensor in here, and remote relay power control to power the motor on an off from inside the house.  Naturally I have two way valves to set the water to pump into my sump when ready.  I now simply drain out 30 gallons, and then pump it straight back into the system when I am ready from the Jayfish relay control panel on my Pi 7″ LCD.

When it comes to power control, instead of cutting off my power leads and running them through relays, I instead wire female sockets via my relays, and control them from there.  Each power socket is connect to one relay, which is connected to the raspberry pi.  This is by far the BEST way to control power safely.  So far I have not needed to control more than 6 items, I have user though who control 16 plugs easily.

If you looked at the cabinet on the right of my display tank, you will  see a tall cupboard which houses my aquarium foods, and also houses the BIG BRAIN of my Jayfish install.  in this cabinet, all my wiring joins up with my raspberry pi,  As you can see I have many LDD LED controllers, I also use ATO feature, and 4 Temperature sensors.  Although I designed a Dosing system so that you can DIY your own, I have not yet implemented it on my tank.  If your running a really complicated SPS coral world, I can see that … but for me I run a soft coral setup or LPS, so I simply mix my basic Calcium, Magnesium, Minerals, Iodine and so on in my top up water.

Yup .. you guessed it, I have the Pi LCD running as a touch screen display.  This screen area is still  to be fully developed.  For the time being it shows you essentials, and allows you to control your manual relays.
