                  this is what i would do ......up water changes to around 75% and clean your filter but make sure you dont disturb your biomedia too much though. supposedly under 50 ppm is safe but your pretty close.

                      If you have a problem with Nitrates, in short this means you have ammonia build up, but your filter is taking care of this problem.
                      I would look at doing a 120-150g water change, and also work on cleaning out your tank of poop and any other debris in the tank. Continue doing water changes in the size of 50-80% each time. This helps a lot.
                      I would for sure clean all the foam filter pads in the filter, and then I would pour all of the lose media in the filter into a bucket. Then take water from the tank and use it to clean lightly the lose media in your filter. This will not kill the bacteria, but get all the big debris off the media.

                        test the tap.....could be coming out high.
                        I ate my fish that died.

                          In addition to everything said, I would suggest that you do not underestimate the importance of a quality water conditioner. I personally have been using Prime for years w/ the utmost-best results...

                            +1 to all the suggestions so far:

                            A very wise aquarist told me several decades ago, "The solution to pollution is dilution", which means, water change, water change, water change. As mentioned, if you have nitrates coming out of the tap, then you're just adding nitrate with each batch of new water. There are ways to handle this if that's the case. Some plants are nitrate sponges, most of which, unfortunately, won't survive your fish. You can set up a wet/dry with a large enough sump to use as a veggie filter; add a couple clip-on lights of 6500K from lowes or home depot over the sump and throw some anacharis, or duckweed or wisteria in it to suck up the nitrates. I'd have another filtration system on this tank even if there wasn't a nitrate problem. I favor multiple filtration and have it on all my larger tanks just in case one filter dies.
