How to bring PH down...

[thanh386]

My pH is currently 8.49. Is this safeand if not how to bring it down

Close the windows and run in place. Oh wait, as full of hot air as you are, I am sure it isn't a lack of CO2. Seriously though, I am following. I don't have the problem now but may run into it one day.

Take offline the CR-8. Way too big for your system.

I've always heard that if you add baking soda it will bring the PH down. I used to use it in freshwater all the time but haven't tried it in a saltwater tank.

Probe calibrated?

 

[thanh386]

I might have to calibrate. Doesn't calcium reactor bring down pH?

Stop breathing heavy next to the tank!

Edit: the Ca reactor should bring the pH down.. what is the effluent reading. Do you dose Kalk could something be wrong with doser?

 

[schwaggs]

Are you dosing Kalk? What is raising pH?

I bet your pH is not as high as you think it is...

Baking soda has a pH of 9 therefore it is a base and will not lower your pH. Would not add that to your tank. Your pH will also be a little different when your lights have been on for a while vs. when your lights have been off for a while.

My average pH has been 8.35 daytime and 8.28 night time. I came home and tank was over heating (84.3) and light had shut off. The pH was at 8.49

Edit: I am not dosing kalk

Edit: Effluent flow is about 1.5 drops per sec

Temperature changes measured pH values. Are you using a probe? Here is a good read on how temp changes pH.

Orlando baking soda has a pH of 9!

 

[schwaggs]

So you are running a CA reactor and not dosing Kalk... I find it hard to believe your pH is REALLY that high. I would look at cleaning and re-calibrating your probe.

Ok I will get fluid tomr. I think everywhere is closed

I learned the other night that you just need to invite a bunch of people over to your house. My pH dropped from 8.36 to 7.93 in two hours.

Yikes! My bad. Sorry, I didn't know that! Thanks for the info.

I got the same problem, my ph is like 8.5 area and im going recalibrate the probe once i get back. Let me know what you end up doing thanh

And let me know if you wanna trade that cr8 for something smaller, like a cr 6

Let me know if you can't find any. I couldn't find anyone locally had both 7 and 10 so I ordered a bunch from BRS.

Baking soda raises it. Acid brings it down. I wouldn't worry about it too much at 8.5 as long as it is stable. If you really want to bring it down, add about a drop of Muriatic acid. About a 1/3 gallon of that stuff brings my 25,000 gallon pool down 2/10ths.

Thanh, just pee in your tank. That will fix it.
