Co2 Regulator With Ph Monitor

[IlliniGuy18]

Is the PH monitor really necessary???

No. I have previously had success with injecting CO2 24/7. Test for pH just before lights on and after lights off. This is your pH swing, it it's less than say 1 i.e. pH 6.5 just before lights on and pH 7.5 after lights off, then you'll be fine.

Another cheaper option, that will also save you CO2 is to buy a solenoid that is simply linked with the lights. This can also help minimise pH swing.

With a 72 gallon tank do you think I'd have any problems?

Water volume isn't a factor alone.

Fish stock and plant density are the biggest considerations.

Plants use CO2 and produce O2 with light. Use O2 and produce CO2 in dark.

Fish produce CO2 and use up O2 all the time.

More fish = more CO2 production/lower pH, less O2

Unless you are overstocked with fish and understocked with plants then you should have no problems, in any size tank.
