    perhaps you can state your own experiences, then we can compile/confront waterworks with the findings.

    Mmmmm...I don't find anything weird about my tap water though. I live in Queenstown area and chris you are in clementi area...water from same waterworks? With the current high temperature, lack of dissolve O2 in water might be a problem for the fish. Try increasing surface turbulence but no so much.

    I know that Charles of Biotope has been complaining about fish death following water changes. My office in Ayer Rajah Industrial Estate has similar problem, shrimp death following 30% water change. Ironically, I have not changed my water in the office 1-ft cube in over a month, only topping up with overnight water from Tampines, no problems.
    why I don't do garden hybrids and aquarium strains: natural species is a history of Nature, while hybrids are just the whims of Man.

    Well, charles mention to me that he never add anti-chlorine or anti-chloramine stuff when doing water changes...might be the recent increase in dosing of chlorine or chloramine causing problems? Or is it water tank contamination?

    FYI, for those who do not know this fact:

    in any residental building (flat, condo, apartment) from 1st to 4th storey, directly water from water main, above 4th storey, water from water tank. so the chlorine or chloramine level from the main will be constantly present

    just got back:
    1 dead apisto nissenji and 1 dead apisto trifiascata..

    I notice this with both apistos.
    a) gill damage, breathing at water surface,
    b) coloration goes dark (stress)
    c) fins all flare up

    I've had cloudy water recently following 50% water changes. I suspect bacteria die off in my filter and the cloudiness is a bacteria bloom. Normally clears by itself within days.

    I'm wondering if chlorine/chloramine in the water damaged the bacteria in the filter. It could be higher levels of these chems or the temp affecting

    Higher pH and temps raises the NH3(toxic):NH4+ ratio in total ammonia. See here for more details. (Note: with reference to the chart in that link, 68F = 20C, 77F = 25C, 82F = 28C and 86C = 30C)

    pH is a bigger factor, so it does not help that my tap water comes out at 8pH.

    On Thur, I drain off my 4ftx2x2 tank, remove all gravels, top-up 100% water direct from tap. No anti-chlorine added, no problem with the fish at all.
    Bt. Panjang area.

    Did 50% - 95% of water changes to my tanks weekly. Just add a few extra drops of anti chlorine/chloramine to play safe. No casualty. Bukit Batok area.

    Maybe you can try to clean your filter media?

    Recommended by ppl from other forum. Maybe you can check out this product -> MYERCIN-K
    It's a small bottle with picture of a discus. Cost around 12-14 bucks. I think C328 has them.

    Cloudy water? I get that before. No casualties. What I added into the water after the recent 100% water change and rescape: Nutrafin Aqua Plus.

    The price should be 500ml for $10 and 2L for $20. If I dun add that, chances of having casualties is high. BTW, I stay New Woodlands area.

    However, the cloudy effect only goes off 2 days later. So now I put a bucket of water and age it for 2 days for water change. Normally I stagger for my 3 tanks and each time is 10 to 30% change only. [:]

    Here is something for Cloudy Water:

    so either I have a tank of doom #3 episode again or something..

    this morning/last night
    1 cory veneuzeulanus
    1 apisto hongsloi
    1 apisto agazzizi
    -------------
    however it seems that each time I water change something dies.. won't change water for another week. will report what happens on my next water change. who knows it could be something in the water tank itself (like that block that found oil in their taps or was it ddt)


    treating the tank now with bactrocide now (P-Toluene/sulfon-chloramide)

    yes, I do have some copper piping, however, copper is first to affect inveterbrates, my yamatos and malayans are doing fine(besides getting eaten by dwarf chain loaches)


    ------------------------

    over the past 3 days, I've lost
    13/6/2003 (water change done)
    3 dead eirmotus octozona
    1 dead rocket pencil
    1 dead c. pygmaeus
    1 dead c. napoensis
    1 dead c. dunno what
    1 dead c. panda.
    1 dead c. venuezeulanus


    14/6/2003 (water change done:treat with befuran)
    1 dead eirmotus octozona
    1 dead apistogramma cacatuoides 'super red'
    1 dead c. pygmaeus
    1 dead rocket pencil


    15/6/2003 (treat with bactrocide )
    1 dead apisto nissenji
    2 dead apisto trifiascata /biteanata
    1 dead apisto cacatuoides 'orange flash'
    1 dead eirmotus octozona
    1 dead apistogramma hongsloi (showing signs of dropsy)
    1 cory veneuzeulanus
    1 apisto agazzizi

    16th morning (today)
    no dead fish.

    -------------
    I'm putting this down to either something wrong with water, or poor quarantine, since I introduced like a few new cories to the tank (although not many of the new cories are affected)
    2x adolfoi,1x duplicarious,4x atropersonatus,2x goldlines, 10x cory venuezelanus,2 x panda, 5x rocket pencil)

    of the new fish.
    2 x rocket pencil
    2 x cory venuezelanus
    1 x panda
    have died.

    its my older apistos in my tank that are hardest hit.

    I stayed at Jurong East, last week did a 70% water change without anti-chlorine. So far no problem with large water change.
