Ph Remains At 8.8....

[huanjie]

HI,

My tank has been running for 6 months, and the PH has been consistently kept at 8.8 which is higher than reccomended.

Since most discussion around aquarium is on how to raise and maintain PH at 8.3, so I assume that the PH will eventually drop to 8.3 if I let the tank takes its natural course, but six month has pass yet no drop.

Should I lower the PH by chemical means or should I just stop maintaining the carbonate alkalinity dKH to let the PH will drop ? Any danger in doing that ?

So far, the coral and the fishes seems ok with the high PH....

Please advise... thanks !

By chemical means will work i think.... such as using the Seachem ph8.3

THis method need u to consistently mix with water and add to your tank daily...... should be huh?

Are you overdosing Kalkwasser? Or maybe something wrong with ya test kit?

[Ammonit]

what kind of test kit are you using?

[coralreef]

like making cograt drink for the tank....

I suggest you double check your PH levels with another set of test kit.

Sometimes, expired or faulty batches of test kits will give you erroneous readings.

Test your KH as well... and report back.

maybe water changes???

Thanks for the replies ,

I am using the digital ECO pH.

It was reading 8.7 - 8.8 since the day I calibrated the meter... so should be accurate I think,

I have not been dosing kalkwasser at all, only use the seachem Reef builder to maintain the dKH. Is that ok ?

Is pH 8.8 bad for the health of the livestocks ?

if i were u i change water..

i have ph eco pen and aquasentry(probe type) ph.

eco pen always give u the same ph even u add

once i try testing on both of my eco pen & aquasentry.

my eco pen always give me the previous/different measurement. (u need to test it at least 3 times to get the average ph.)

while aquasentry u get the result straight away.

*try to calibrate ur eco pen. and try it again.

did u wash ur eco ph every time u use it?

Tried changing water, but doesn't seems to have any effects on the pH, I think Anthony is right,

I need to re-calibrate the Eco pen..

Thanks again !

My guess is your reef builder thats playing your water foul. Decrease or stop dosing that at the moment until your pH gets back to 8.3. If you have a problem with this level of dkh, get a calcium and dkh test kit to test your water parameters. Your dkh needs only be maintained between 8 ~12 dkh and calcium levels at about 420ppm

Update on the issue ,

I have recalibrated the Eco PH pen , it was drifted 0.1 higher, which means the pH is still high at 8.7.

The dKH has been maintain at 8-9 and calcium at 440 to 480 by menas of reef bulider and reef advantage calcium alternate week water change is done with tropic marine salt. Newdamsel might be right, it could be the reefbuilder that prevent the pH to settle at 8.3, now I will try to let the dKH drop so that pH will drop before start dosing the reef builder.

I will bring a sample of water to Henry to verify the water parameters to confirm.
