Nitrate Poisoning of Livestock affirms that Nitrites rather than Nitrates will give the brown colour, but I can't find any evidence to suggest no...
In that case the humidity sensor and Arduino actually makes sense, so you can add on as you go. I'll be using a PIC18F2550 (ordering 3, only...
Normal 20W!!!! and 60 LED? any other info in it? If running from batteries, I can almost promise you it is not nearly strong enough for a tank...
Oscars grow at about 1 inch (2.5cm) in length per month, or so I hear. They do grow up to 30cm in the home aquarium, so be prepared. 50G (around...
Wow, why are Arduino and its shields so expensive?? Looks nice! Does your glass thermometers also read around 24? And why do you want a humidity...
Okay, firstly, I do not trust that health shop with anything! And suspiciously when you Google KDF filter you get a lot of sites that I will NOT...
What type of sensors do you guys need? Mine will be using a PT100 probe or similiar for temperature, and a CdS photo-resistor for the colour...
That was one awesome TED talk! Was glad when Google Reader dumped this in my download queue from the TED site. Almost made me buy a Arduino, then...
All together now; Hi Coen... Welcome to the forum, hope to learn a lot from you, and hope you learn a lot from us :)
When I submersed my LED's I a had better view in the container. I think LED's can be nice on Fish-only systems, but currently to help plants along...
it is 14'000 mcd instead of 1'400 mcd then it might be worth while, but still, if you would like to grow plants in there, rather go for cree LED's
Well, before somebody flames me, I know the units I'm about to use does not relate 100% and can't be used as is. Best would be to visit a topic...
Sailfins are awesome! In my opinion people are not informed enough, so many family members kept Balloon mollies because: "they are so cute". After...
Do you want the Watts to know how many power it will drain? Or how much light it will give. For the light intensity, rather look at the 1400mcd...
Just remember, the area of a circle increases with a power of two, not linearly. So 20mm ID pipe as an area of 1256.6mm2, while 40mm ID as an area...
I can't say, best you can do is test is, or look online on engineeringtoolbox for the relevant equations, 6 sixpacks of red bull and a third year...
My issue with pH probes is how often you need to calibrate them. And for temperature I like to use a simple thermistor, but LM35 would also work....
Is this billion in the US system (10^9), or SI Billion (10^12) that we use in South Africa?
While you all go on about thermometer accuracy, please bear in mind that Repcal (the place that calibrates digital thermometers in South Africa to...
You could always add a second overflow, say on the other side of your tank, that will double your overflow. Your only other option for increasing...
