[APD] CO2, bubble count
Hello Folks:
Thanks for the info Rich.
"Needle valves are not fool proof. They have been known to :"slip"
opening up to allow dangerous levels of gas into the tank. i have had them
perform for 3-4 years and suddenly fail. I believe that a device sold to
monitor the pH and shut the system down when there is a drastic drop which occurs
when there is a massive CO2 flow would be worth the expense. I have heard
that the leads are an issue and need replacement. Someone pitch in here."
Would you be willing to share which device for controlling pH you might recommend?
My CO2 is not feeding into the cannister filter. It is directly in the tank and set near the outflow to ensure
mixing and absorption. I am currently set for 3 bubbles every 25 seconds. The diffusor is then emitting very
fine bubbles I can barely see. I am takeing daily pH measurements to get some idea of the relationship between
the bubble count and pH. My question is whether I am in the ball park or way off course. Does anyone else
have some pointers for me.
I will be ordering a bubble counter, but would prefer to have a better understanding of what is going on in my tank.
By the way, what does happen to the needle valve to cause it to fail and let the CO2 flow uncontrolled
smothering or acid burning the fish?
