    Hi,

    I am wondering is there such thing as "your fish tank is no longer usable" B'cos what fish i put in the fish, it will not last 2~3 days. I have completely overhaul the filter material with new substrate and bio rings. Still death is unavoidable. Even with 20% water change.

    Btw my tanks is 30cm X 20cm X 25cm
    Filter is Eheim liberty 150
    Fishes: 8 pcs of guppies


    Your conclusion?

    Give it time to cycle. Please use the search function. You are likely to get a lot of information.

    You can search for "cycle". Here's a link for your reference.

    New tank

    One short-cut to new tank cycling is to use water from water from older (stabilised) tank.

    A slightly more risky (lazy man's method) is to use conditioned water, i.e. tap water with anti-chlorine/water condition and left overnight.

    If you want to "test" the water, you can start with a cheap betta, or a small pack of feeder mollys or guppys. But feeder fishes are typically not in the best of health and you cannot ascertain if they are cleared of contagious diseases/parasites.

    I have been using both methods and extremely rarely encounter total wipe-out.

    I have a question, what do you do to the fishes after you used them to 'test' the water?

    Continue to keep them!

    A better test fish would be platy, they would eat the protein film at the surface of the water. However, I would only add the test fish only when I'm rather sure that the water is fine and the plants are doing fine.

    Throw away the dead ones and continue to test with those that are alive.
    It's not just "Step1: Add Water, Step2: Add Fish" If everything else don't work, add plastic plants and fish

    It isn't ethical to buy fishes as test kits.

    It would help to get aged aquarium water, or ask around for old unwashed filter media. Use the filter media in your filter, it would help greatly with the tank cycling.

    Certain fishes are resilient, others are very sensitive to chlorine. Are you using a good de-chlorinator for tap water?

    plant more plants,
    add conditioner - i recommend seachem prime.. good stuff for me
    use their seachem stability as well... i find that it works well compared to some other brands of bottled bacteria
    i had a brand new tank, gravel, filter everything for my 2mth+ old setup

    what i did was dose seachem stabilty daily for 2 wks
    stability also added for weekly 30% water changes for about 1mth+
    seachem prime with every water change and even with the top up water every 2 days
    did 50% water change at end of 1st and 2nd week as well as clear out plant debris
    added otos and shrimps 2 dyas after 2nd week water change
    rasboras one more week after that
    did my1st filter wool change 1 week after that (initial 1st mth filter wool gets very dirty cos of all the fine gravel particles floating around and the plant debris as plants acclimatise to the environment)

    tank so far very good...no unnatural deaths ( 1x rasbora jumped out and dried out on the floor is quite natural =p )
    stopped using stability with water changes after 1st month+ or so

    now i just use seachem prime with all water that goes into the tank, both water changes and top ups
    oh btw, i also let my water air overnight for at least 1 night before they go into my tank.

    it sounds easy this way but it worked for me and i guess sometimes its just some luck
