I find the controller to be overkill honestly. Why did your co2 not turn off overnight?I'm considering buying a pH controller to monitor the pH of my water and turn on CO2 when the level goes above my defined level.
Does anyone have one and recommend it?
I currently use a timer to turn the CO2 on an hour before lights on and off an hour before lights off, then have the air pump running overnight because the plants aren't giving out oxygen and I noticed the fish gasping without it. My concern is if the CO2 doesn't shut off overnight and the fish get gassed. I've already had one very close call with gassing my fish and I really don't want to repeat it. Can someone put my fears to rest?
I have the Milwaukee SMS ph controller and while I like being able to see what the ph is I have to admit I believe they are kind of a waste of money. If you have your CO2 hooked up to a timer that goes on when your lights go on I would say to find something else to spend your money on as the ph controller is one of those pieces of equipment that are not needed.
:thumbsup::thumbsup: x2If you are able to run your tank successfully with considerably less than the maximun CO2 concentration that the fish can tolerate, in other words low to medium light, you can use a controller and run the CO2 24 hours a day. It wastes CO2, and puts the fish under a bit more stress than necessary at night, but it shouldn't kill or maim the fish. That would seem to be the optimum way to have consistent CO2 concentration at all times. But, if you have high light, and need the CO2 concentration up close to what would harm the fish, then if the CO2 runs at night the lack of plant consumption of CO2 will probably raise the concentration enough to harm or kill the fish, even though the controller should shut off the CO2 before that happens. So, I might think of using a controller with low light, but never with high light.
agree completely with this statement.wasting co2 a night with a controller is a way overblown
the time it takes to go from one set point to another is directly related to the co2 injection rate , diffusion method,and rate of consumption and off gassingJust to follow up on this; I've had it in place now for a couple of weeks, with desired pH set to 6.5. What it does is wait until the pH goes up to about 6.55 then turns the gas on until it gets down to about 6.45 and switches off. It seems to take about 4 or 5 hours for the pH to drop and switch off.
I've not noticed any difference with my plants but what I have noticed is that I think I was putting too much CO2 in before. Given that it takes 4 hours to get the pH down to 6.45, and I was running it for double that I suspect the pH was dropping quite low. This just takes the guess work out of it.
Second observation; my fish seem happier - the clown loaches especially. Before they seemed to spend most of their time sleeping in their 'Clown Cave', but they're out almost all the time now. That backs up my thought that I was adding too much CO2 before.
Third observation; because the CO2 is off for periods during the day, the water actually looks clearer due to there not being a CO2 mist in the water. I really like that. I was never a fan of the fizzy pop look - the water looks crystal clear now.
So, those are my observations. I personally quite like having it - just for the amount of control it gives to the equation.
