Ca Demand Low? Cycle Co2?

[Diesel3443]

Hey guys currently with my bioload low I run my calcium reactor at a pH at about 7 to partially dissolve the media. Is this ok or is it better to run at a lower ph and saturate the media for a period of hours throughout the day. Im wondering this because maybe, at a lower ph, are more trace elements dissolved? Or is how I am currently running it ok to do? TIA

Sean, that's how I run my CR now. Run for Low pH for 6hrs a day. Depending on the bioload, I adjust the running hrs accordingly.

Do you run it with the lights on, and then not when the lights are off? To keep ph at night as High as possible?

Sean, I just put mine on a timer last night.. I am going to run it 18hrs a day and see what it does. I have been running it 24/7 but ph was like 7.7-7.9. Trying to run it 18 hrs now during part of lights put but all the time during lights on to see if I can get the PH up.. I already have my air intakes from my skimmer hanging out a window to get fresh air.. It raised it from 7.6-7.8 to where it is now.. I will def report my findings after a couple days and also check water parms to make sure they stay constant.. If not it goes back to 24/7..

Jeff my ph in the reactor is about 7.0, im wondering if at a lower ph more trace elements are released. If not I will keep my reactor as it is because my tank is stable and I do not have a ph issue anymore. It is at 7.90-8.09. Let me know how it goes If there is any changes in coral health.

Will do.. I run mine out of my second chamber at 6.9 so the first chamber is prob around 6.6...

I start the CR about 4 hrs after the main lights comes on.
This helps to keep the pH at night high.

After 2 nights on the timer 18 hrs a day my ph has raised from 7.9-8.1.. night to day... Thinking after a few more days maybe it will be 8-8.2 again woohoo....

Thanks For the input Jeff I may have to get a timer
