    Having too much of a bioload will not make you loose your cycle, it just means your fish are producing more ammonia than your fitration can handle

    Follow the exact same steps as you would if you were cycling with fish (link below in my sig)

    Did you change anything in the tank resently ?
    If you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease.

    +1 with Cliff's post - we assume you mean you started having readings for ammonia? What kind of filtration do you have on that tank?

    I concur with both Cliff and Adrea. That big tank and those large fish probably should have two canisters on that tank.

    Also, a cycle can be set-back from forgetting to add dechlorinator, changing out filter media or not doing enough maintenance which can cause the pH to drop down too low.

    I have a mega flow sump and a rena xp4 canister filter. Over the last few months I have been away alot so I have negleced the tank but not intentialy. I have readins of ammonia and no nitrates. I have been doing large water changes.

    What do you have as far as media in your mega flow sump?
    Does it hold beneficial bacteria in a sponge or within the media?
    How are you service cleaning it?
    Are you being careful to not damage the bio?
    What size is it and how much area is designated to bio media?

    The Rena Xp canister has the same questions applied.
    How are you service cleaning, the media and such.

    Also, are you staggering the service of these units or doing the cleaning of both units at once? Both at once is not recommended.

    When you cleanse them are you using aged water with no chlorines etc?

    You should not have lost your cycle from a PH crash as you still have fish alive that do not tolerate low PH.

    Keep in mind that if your water from the tap has chloramine in it and you are not properly removing this chemical, your ammonia level will be high. Also, most test kits read the ammonia portion of the chloramine and some read the bound ammonia after the the dechlorinator has been applied. You may need to adjust the product per your area. With the drought, many locals have begun using chloramine as their initial water product has been affected and chloramine is more stable in the water.
