SRC Member huanjie Posted September 1, 2003 SRC Member Share Posted September 1, 2003 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 ! Quote Link to comment Share on other sites More sharing options...
SRC Member berrykin Posted September 1, 2003 SRC Member Share Posted September 1, 2003 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?

FuEl Posted September 1, 2003 Share Posted September 1, 2003 Are you overdosing Kalkwasser? Or maybe something wrong with ya test kit? Quote Always something more important than fish. http://reefbuilders.com/2012/03/08/sps-pico-reef/ Link to comment Share on other sites More sharing options...
Ammonit Posted September 1, 2003 Share Posted September 1, 2003 what kind of test kit are you using? Quote Link to comment Share on other sites More sharing options...
SRC Member coralreef Posted September 1, 2003 SRC Member Share Posted September 1, 2003 like making cograt drink for the tank....

Achilles Tang Posted September 1, 2003 Share Posted September 1, 2003 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. Quote Link to comment Share on other sites More sharing options...
SRC Member junyong84 Posted September 1, 2003 SRC Member Share Posted September 1, 2003 maybe water changes??? Quote Link to comment Share on other sites More sharing options...
SRC Member huanjie Posted September 1, 2003 Author SRC Member Share Posted September 1, 2003 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 ? Quote Link to comment Share on other sites More sharing options...

Is that ok ? Is pH 8.8 bad for the health of the livestocks ? 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?

SRC Member huanjie Posted September 1, 2003 Author SRC Member Share Posted September 1, 2003 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 ! Quote Link to comment Share on other sites More sharing options...
SRC Member newdamsel Posted September 2, 2003 SRC Member Share Posted September 2, 2003 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 Quote Link to comment Share on other sites More sharing options...
SRC Member huanjie Posted September 3, 2003 Author SRC Member Share Posted September 3, 2003 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. Quote Link to comment Share on other sites More sharing options...
