i have a 225gal tank that ive had for about a year 1/2 now. recently my nitrates have been at the bottom of the chart. ive done three water changes and my last water change i did 170gals all at once and they only came up a little on the chart. what else can i do? im sure my fish are near death. the algea is my tank is taking over because my nitrates are so high, so please help.
