Ph

[Darrell Brady]

I have a large reactor wanting to fill it with crushed coral an run a slow flow of water through it. would it have any positive affect on the PH?

Evening

Just wondering what the goal is. Calcium reactors lower ph to dissolve the calcium, but I would not see any benefit of running water thru a basic reactor filled with crushed coral to alter ph

 

[Darrell Brady]

just wanting to boost the PH a little bit being I had that reactor laying around. but if it isn't going to make a difference not going to mess with it.

Cool, always good to try new things.

Where is your ph now, are things going good or bad in the tank. Sometimes it’s not the number as much as the stability. Unless you ph is in the damaged zone.

I have my skimmer drawing air from the outside the best I can get is about 8.0 dropping to about 7.8 at night. was hoping to bump it a 1/2 a point or more.

 

[Mastiffsrule]

That’s sounds good to me. You can try a reverse photo period to keep the ph up at night or try to get a bit more surface agitation, but I think your good.

 

[Darrell Brady]

Yea I have fuge running reverse at night. Just Had a brain storm thinking that it might buffer the ph a bit more.

 

[Darrell Brady]

Might try it any how an see what happens don't think it could hurt anything.

Only if the pH is already very low (well below pH 7.8).

What is the pH?

It won't.

The lowest it might get would be about 7.7

Does bacteria an Fish produce CO2? I can never get my PH up to 8.2 even if I open my windows.

I never really had success with just opening a window either, but one window never really allowed any airflow or breeze whatsoever. I have a condo so all my windows are on the same side of the building which limits any real air flow.

What I did was put a window fan in the furthest window from the tank to draw air out and opened the window nearest the tank. My ph went from 7.8-8 to 8-8.2 within 24 hours.

Yes, and if that's the case, more aeration helps.

But the measurement may also be off.
