    How long has the tank been set up? Sounds like it wasn't completely cycled before fish went in or you put to many fish in at once and caused a mini cycle.

    To me it sounds like a mini cycle. You shouldn't have had any ammonia or nitrites. When you start seeing this pop up its usually a mini cycle but you also say very high nitrates. Do you have dead plant leaves in the tank? This could also cause the problem.

    I would also look for a dead fish.

    i have removed the dead leafs from plants and took them out and re put them in, no dead fish like i said everyone is still alive and swimming

    Do you take the plants completely out of the tank when removing dead leaves? It could possibly be that you are getting some leaching out from the substrate when removing the plants, could be wrong just spitballing but it would make sense.

    If these are your normal perimeters I don't think this tank has completed its cycle. A cycled tank should read 0 ammonia, 0 nitrites and some nitrates. An uncycled tank can do what you woke up to this morning.

    I would do several small water changes to get the PH back up to its normal level and then add some crushed coral in either the filter or actually in the tank. As it very slowly dissolves it will help to keep your PH stable. It won't happen instantly but it will help from now on as long as you replenish it as it dissolves.

    If you don't already use it I recommend getting a bottle of Seachem Prime. It will neutralize both the ammonia and nitrites and make them safer for your fish. Water changes and Prime will eventually help this tank complete its cycle.

    Any changes to your filter media that could have caused a spike or mini-cycle? Like did you change out media or rinse it under the tap, anything like that?
    Also might be a good idea to test your tap water to check those levels.
