For my birthday last Friday I got a Seneye Reef device from my parents. I’ve been looking at it for some time since it seemed like a nice handy device to me, and now I finally have one.
When I wanted to try it I got disappointed by the fact that the card need to soak in water for 48 hours, this also limits you to one aquarium with one device. At least so it seems for now…
I installed the software on my pc and put the card in my aquarium to soak.
The Seneye device has couple of ways to work, one is directly on a pc that is turned on. This way it will constantly update the server and track your water values.
Another way is through a USB->Power plug. The Seneye device keeps track of all settings but will not sync them with the pc or your website until you attach it to your pc.
Third and my preferred way for the future is on a Wifi device. Downside is that you still need your pc to sync the values with your pc and site, but it saves power. This is something that needs some thinking and planning on how I will make this work.
After having the card soaked for more than 48 hours and the device charged for more than 1 hour I put the card in the device and put it in my aquarium. It didn’t take long till I had my first values, Ammonia being 0.001, PH 8.35 (little bit high) and temperature 24.8.
Unfortunately it seems the website doesn’t play nice with IE8, so I needed to download and install Firefox to get it to show.
Once you get on the website (your personal site) you get all sorts of graphs. First is the NH3 value, this seems to be a constant 0,001 on my crab tank.
Next is PH, this was rather fun to see, in the morning the values are around 8,13 but towards the end of the morning values go up to 8,60 even. It also gives you an idea on what to expect for the coming time.
Same goes for the temperature, you can see the graph go up and down during day and night.
The PAR and LUX values I’m not sure on how to read these, maybe someone has an idea on this how to read these? It looks very nice though :p
The above values are available for your reef overview, here you can also see these values for any other devices you own. When you click the device name itself you get some more values.
First is the O2 value, for my aquarium this was around 7.9 to 8.2. Never measured this before so no idea if this is good or not.
Next is NH4, also an ammonia value. No idea what is good with this as well, it differs greatly, from 5.21 up to 14.18.
Last is the Kelvin value, also a value to do with light, this doesn’t seem to work very well yet on my device. But for the values to do with the lighting, I will dive into this more later.
So far my experience is good with this little thing. More information will follow.
