    Need a safe way to increase the PH level in my tank.
    It is currently at night sitting at 8.6 and higher during the day.
    i would like to increase the level to about 8.4 - 8.2.

    Do you mean you want to decrease it or is your p.H at 7.6 at night? What supplements do you use at the moment so we can help you along and how do you dose them. All at once or at different times. What is your alkalinity and calcium reading at the moment

    I need to get the Ph range right.
    I have been reading a lot and been checking forums and they all say your PH where at night or during the day needs to range between 8.2 through to 8.4. Mine however is way above that. Just need to get the PH is normal range and not the High range that it is currently in.
    The last calcium test i did it came to around 410 ppm. alkalinity i checked last night with the red sea test kit and it was in the Normal range. can't remember the specifics.

    Your PH is absolutly fine and calcium is correct. Personally i prefer running my tank at a slightly raised PH.

    What is your p.H during the day and how do you measure it?

    THAT's a crucial question.

    If using an electronic pH meter, how often is it calibrated (and in what range...). If using a colorimetric "liquid test", what make are you using, and how old is the reagent (reagents have limited shelf lives). Also, is it a dedicated "marine" test reagent - fresh water test kits give false readings when testing sea water...)

    If your tank looks fine, then don't chase numbers until you are sure of the facts :)

    I have to check this week end. Get home to late during the day to test. i am using Red sea marine test. Will exp date on the bottel.
    Begs the question how reliable is the red sea tests.
    thanks for the info.

    The red sea pro tests are a whole lot better than the regular ones but a calibrated p.H meter is first prize. I really dont trust titration test kits when it comes to p.H. You can take freshly drawn water from your tank to have it tested at your nearest pet store but you cant have the water lying around for hours before testing as the p.H will shift

    thanks.

    What i meant by this
    ''Need a safe way to increase the PH level in my tank.
    It is currently at night sitting at 8.6 and higher during the day.
    i would like to increase the level to about 8.4 - 8.2.''


    Your PH shifts between at night. When I have tested it was higher at night than during the day.
    I needed to find away to increase the PH level to the recommended figures of 8.2 - 8.4

    You got it wrong, increase means to raise or make more. You want to make it less or decrease, not increase :p

    And always double check/measure pH before making changes as the kit might be out or the pH meter not calibrated.

    This is totally opposite to how it should be - the pH is usually increased during the day (due to photosynthesis using up CO2), and decreased during the night when respiration adds CO2 (CO2 turns to carbonic acid, which drives pH down...)

    Please describe in detail how, and when, you do the pH test. Also, why don't you give us some more information on your tank - how old is it, what filtration do you use, what bio load do you have in the tank, etc - that can help us to understand your system, and then we could perhaps find a proper answer to your question.

    I just tested my pH at 530pm and it read 10-11... is this bad! (sera test kit)
    and my Ca at 470ppt (salifern)

    Your p.H is way too high but then I dont trust titration tests. I think at a p.H of 10-11 all in your tank would be dead. Your calcium is a tad high but not out of wack. It should be around 420-450ppm. I assume you meant part per million and not per thousand which would change everything

    yes ppm:whistling: its 450-470ppm
    and the pH took 9/10 drops then turned green and the 11th drop yellow = 11pH

    don't trust the pH either:lol:

    Well, either it is true, and everything in your tank is dead (bad...), or the reading is totally wrong, and (fortunately) all your livestock is still alive :whistling:

    I suggest that you check the instructions, and if you followed it to the letter, then replace your test kit.

    What is your kH if calcium is 450-470?

    Go to a pet shop that has a digital p.H meter and ask them to test it. Most of them wont even charge you for the service
