    Default PH drop & testing KH & GH


    0 Not allowed!
    While my tank was cycling (fish in) I noticed my ph would drop so I tested my tap waters KH & GH and if memory serves I had a reading of 53.7 ppm GH/KH so I began adding crushed coral to my canister filter (about 1 cup) and my ph held between 7.2 - 7.6 (ph out of the tap is 7.6). So between adding the crushed coral and doing daily 50% water changes my ph stayed stable.

    Now that my tank has cycled I started testing my water and doing water changes only on a weekly basis and my ph is again showing issues of instability. During the day it tests at about 7.23 but has dropped all the way to 6.62 by the morning then it starts to climb again. Adding fresh crushed coral to the filter and adding an additional cup of it (hanging in a media bag in the tank) hasn't really helped the problem. I've also done 3 days of 50% + water changes and that hasn't made much of a difference either. Water parameters are 0 ammonia / 0 nitrites / 0 nitrates (usually 5-10 but have just done 3 days of pwc's).

    I tested the tap water again this evening - PH 7.6 out of the tap and the KH/GH were as follows: KH = 3 drops to turn water yellow (light yellow not dark). GH = 6 drops to turn water green (light green not dark).
    What exactly is my ppm GH/KH?

    Even more confusing is my 10 gallon QT tank PH has tested 7.6 for three days. No live plants in there or driftwood though, I do have 5 live plants and a 10" x 2" piece of driftwood in the tank with the ph issues.

    Any advice would be greatly appreciated.

    Why are you trying to adjust it?

    Fish do better with a stable pH - they get stressed if you keep trying to alter it.

    Many fish do fine in a range of pH, plus, it doesn't stay stable when a tank is cycling either.

    It sounds to me like dissolved CO2 is building up during the night, making the PH drop. You can add an airstone at night to help drive off the excess gasses.

    Here is a conversion chart, assuming you are using API, http://cms.marsfishcare.com/uploads/...9%20insert.pdf



    0 - 4 dH, 0 - 70 ppm : very soft 4 - 8 dH, 70 - 140 ppm : soft 8 - 12 dH, 140 - 210 ppm : medium hard 12 - 18 dH, 210 - 320 ppm : fairly hard 18 - 30 dH, 320 - 530 ppm : hard higher : liquid rock (Lake Malawi and Los Angeles, CA)
    (taken from: http://www.cs.duke.edu/~narten/faq/chemistry.html )

    What is the GH and KH in the tank? It is normal for pH to fluctuate in nature, sometimes well over a point, I think stable GH and KH are more important, but I know others will come along and disagree.

    When I go fishing I just place a sharp rock in the water and sit there waiting for all the dead fish to float to the top... Kingfisher
    Brutal honesty will be shown on this screen.
    I think my fish is adjusting well to the four gallon, He's laying on his side attempting to go to sleep on the bottom of the gravel.
    Tolerance is a great thing to have, so is the ability to shut up.

    I can explain it to you, but I can't understand it for you.

    I do run a 12" bubble wand 24/7 but can easily run another over night to see if it improves
