I think carp are a lot more hardy than other fish, but optimum conditions are best. I use Seachem prime to detoxify nitrate.

even if its true, cant hurt to keep em down as much as poss. can it

My uncle keeps koi and he has nitrates in his water. His have been doing fine for 10 years so I guess they are pretty tolerante, unless he does something to keep them down.

Koi and goldfish are very hardy. But just because they can withstand high nitrates (and ammonia too, even, EG people cycling tanks with goldfish) doesn't mean it's good for them.
