    Tank water.
    First problem I'm seeing is the nitrates. You really should increase your water changes to bring those down to at least 20ppm. Second problem I'm seeing is the ammonia. You really shouldn't be seeing any of that in a nicely cycled tank. Third problem is your pH. Are you using something to lower the pH? A pH of 6.2 - 6.5 basically means that your cycle is only really working at around 25% of what it should be, which could explain the .50ppm ammonia reading.

    Tap water.
    The ammonia in your tap water is super high. This is probably because of a high amount of chloramines being used by your supplier. What you should be making sure of, is that you have a dechlorinator that breaks the chloramine bond (seperates the ammonia from the chlorine), and detoxifies/neutralizes the ammonia. This way, the ammonia that is left in the tank won't hurt your fishes while your bio filter (cycled media) consumes it.

    So apart from the highish nitrates, the only other thing that could be triggereing the diatom bloom is high phosphates and silicates. You can buy test kits for those things, which is what I would do, just to see what those things are looking like. Then we can work out what action to take to fix that problem, if there is any problem.

    They sure do, Mandy!
    Three-fourths of the Earth's surface is water, and one-fourth is land. It is quite clear that the good Lord intended us to spend triple the amount of time fishing as taking care of the lawn. ~Chuck Clark

    Are you changing out your filter cartridges or rinsing them out in tank water that you are discarding? If you are changing out the filters for new, then you are throwing out the bacteria (cycle) with them.

    Your tank might be 5 months old but it isn't cycled. You have to make sure you always maintain bacteria in the filters by either just rinsing the cartridges or changing new ones just one at a time. This is why a second filter is always wise.
