panda, I guess I really dont need ph monitoring. I dont test enough, been doing it too long and stubborn. So I like the idea of just peeking at the ph and knowing things are stable.
BUT, in the end I dont need it. I just like the idea of knowing, while not at home, things are cool.
I will look into the reef angel, never heard of that before, and havent coded C++ in about 15 years so sounds fun...
