Plants honestly don't really soke up the nitrates as much as some say.
It's been my experience you're lucky to get a decrease of 5ppm (if that)
in a heavily planted tank. You nitrites are dangerously high at 1ppm
(google "nitrite poisoning").

All I can do is more water changes. This tank has been cycled for well over
2 years. There were 5 good size fancy goldfish and a pleco in it. There
shouldn't be nitrites in the water. You know the poops these guys take. =

Your nitrites and nitrates are so high, it's killing your fish at this
point. Your tank is not cycled.

???

I'm sorry to say, but the only real effective way is still water changes
with gravel vacuuming. But please get the nitrites and nitrates down or
fish will continue to die.

We have an appointment in town in 20 minutes. When we get back I'm going to
do a massive water change with gravel vacuuming. We'll see if that helps.
