Journal 80cm (32”) collectoritis tank

Great setup. How have you found the Up Aqua pH controller? I assume you can just set the PH in a range for a certain time of the day? I wonder does it need calibrating much?

Oh thanks for the tip I see in your earlier post about school of scape. Not that many resources here in Aus in a relative sense so more the better.

It is ok, I got it quite cheap and it suits my purpose.
You set it at the desired pH, and it will activate the solenoid until the probe reads 0.04 under that number, when it will turn off until the probe reads 0.04 above the number. Being not far off a 0.1 ph swing every cycle means it isn’t amazing to use as the main point of control for the tank.
I have mine as a safety barrier. I set it a touch under the pH my needle valve gets the tank to under normal operation.
Technically it shouldn’t ever turn off the solenoid throughout the day, and is there for peace of mind. If I change bottles over and bump something, a needle valve drifts or a regulator malfunctions, then it will shut the CO2 off before the fish are at risk.

I looked at them a few weeks back when you and Rocco were discussing them and they were crazy expensive. I was maybelooking at the wrong thing.... or wrong site. I was going to ask how you knew which one to get, but seems you're ordering a smaller one, so you weren't sure.

Yeah, if you can figure out that you have 30ppm CO2 at one mark and 50ppm at another, then it doesn't really matter what the gauge reads as long as when you put it to where you want it, you get what you expected.

This is cool. I'm not a very technical person. So you had to remove your needle valve to get this installed?

The barbed fittings at the back unscrew and there are 1/8 threads there, which most needle valves will screw straight into.
The valve on these cheapies is useless, and I have left it wide open and just use my normal needle valve, which is connected to the inlet of this flow valve.

As to which one to get, there really doesn’t seem to be a guide or formula out there. The smallest possible seems to be a good starting point!
This one is a 6-60 ml/h, most are measured in litres per hour so I doubt our CO2 flow would even register at all!
Fingers crossed the 2-25 gives a better range, although I am happy enough that the 6-60ml gives me a quick visual check that my CO2 is set about right.

Great looking tank. And even better looking data on your levels/dosing.
