    PH ALERT

    Recently I noticed that my PH reading had shot up from my usual reading of bet 6.5 - 6.8. The PH reading between Sunday (1 Jun 2003 ) till Tuesday ( 3 Jun 2003 ) was around 7.3 and going up .
    I tried dosing with peat and the PH still did come down . I could not identify why the PH was so high .
    I called another forumer (PC) and he told me that some one else was also experiencing the same problem. The PH from his water supply at his place went as high as 9 . I then took a reading of my mains water and the reading was 8.5 .
    Just to let you guys know that perhaps you may want to check your PH when you get home . Many thanks to my friend PC for highlighting this to me .

    PUB's pH for water supply ranges from fluctuates from 7-9...why should you be so surprise? ...Washoff from the banks of the reservoir varies from time to time and hence the fluctuate of pH. Why are you using peat in a planted tank? It does not help your plants at all unless you are trying to spawn your fishes?

    Hey CKS

    Are you getting your water straight from ground or from roof tanks?

    david/sherchoo,
    serangoon : not panic or gabra like that but only to share infor with people using ph controllers . just to let them know that if they don not adjust their water parameters then and they are not aware of this situation then they will be wasting a lot of co2.

    i was listening to some anectodal accounts of fish deaths after water change. also heard a 2nd hand account of a guy calling the waterworks to ask if they are adding extra chloramine (which they did).

    so: ammonia = alkaline, most likely chloramine is alkaline as well.

    http://www.osmonics.com/products/Page813.htm


    so make sure your water change includes a chloramine remover just in case.. you're welcome to verify the facts, I know I'll be checking the KH.

    (ie: singapore tap water, KH should be < 1 as per all my other tests. so if KH < 1 and PH > 6.9 (which was what was typical for my last tap water test), then they have added some alkaline substance... most likely candidate is monochloramine...

    I can then add dechlorinater (sodium thiosulfate) then measure the water for ammonia.


    ps: I was at c328 at 11pm buying some fish food when the aunty was doing water change. then I heard her say "it was doing fine just a while ago" then everyone was rushing about one of the arowana tanks... dunno what happen to that arowana...

    ok. my test on home water. CCK waterworks..

    water is straight out of tap in a rinsed pitcher.

    KH = 3 (yes, different from my usual non detectable kh)
    PH = 7.4
    ammonia test on water after dosing with sodium thiosulfate = not detectable.

    ------------------------
    so chloramine not probable at least on the cck waterworks side..(unless test is faulty. heh)

    maybe its time to get the sera CL test kit

    incidentally, I stay high floor so water from water storage tank

    also: just tested
    for my week old tank water.
    KH = 2
    Ph = 6.6

    (tank has peat,ketapang and co2 injection as well)

    Chris,
    Thanks for the info.

    cks,
    I was asking for your kH level to confirm that the pH is up due to the water is harder or there is a alkaline substance added by the waterworks.
    Cheers!!

    sherchoo : I'm too lazy to check the kh/gh nowadays. perhaps in the region of 5 or 6
    chris : like i just told you & benny yeterday the reason i posted this thread was to alert others that the ph level from my tap has risen to such a high level. i never faced this prob before .

    : ) I just did a full water change lately with hot water bath for my sand.

    Guess what? The water is soooo...cloudy. Took abt 2 days to settle. Anyway it won't kill the fish if u add Nutrafin Water Conditioner - Aqua Plus that is. tested.

    Meanwhile I am having a bucket to "age" the water for future water change.

    PH ar...always around 7++ region for my side.

    The hot water probably killed loads of bacteria in your tank and filter thus the cloudy water....Mmmmmm..why are you using hot water!!!!

    when I say hot water treatment, it means seperating your fishes much like quarantine. Then empty the water tank of plants, sands.

    Once you have done that, u can then start cleaning the tank by scrumbing the tank surface, clear the sand in a small bucket and filter them with hot water a few times to get rid of particles, germs, etc.

    After that you can replant the tank, re-org the sands and any logs, fill in the water, condition the water. After the tank is stable then add the fish lor.

    You think I add hot water directly ar? Heh Heh, if I did so, I'd end up with extra dishes for my dinner. []

    Oh I see...hhahahaha...but why in the hell would you want to do that? The amount of nutrient that has gone to the substrate level due to the mulm buildup would be gone with your kind of cleaning.....Just do a large water change and then correct the conditions accordingly should do fine? There is simply no need to do what you did unless you are rescaping...

    Call it the garlic syndrome. Wipe out 20 over tetras...only the black one survived..along with the one-eyed gold fish (lost when being attacked in the early days)...2 grass shrimps survived, yeah, so did the algae eater and otos. ^^" so did the guppies...just the tetras affected.

    Then...the plants din survived much after I went for my reservist. So I might as well, re-scape it.

    if it were me, I would have just emptied out all the fishes. empty whatever non hardy plants. dump half a bottle of h2o2. and be done with a water change after 15 minutes..
