hi
I am curently doing a fishless cycle, so here are my levels..
ammonia- 4.0-5.0 ppm
nitrite- 10 ppm
nitrate- 50
pH- 7.6
water temp.- 81

My question is should I do a water change to get my nitrate down? or should I leave it how it is and see how it turns out?
Thanks for your help!

Don't bother changing water.

I think you are supposed to reduce the daily dosage of ammonia when the nitrites show up. The nitrite processing bacteria do not like ammonia.

I'm worried that your nitrite levels are too high and your cycle may have stalled. How long have you been cycling this tank? If you haven't seen a change in nitrite levels in about a week I'd suggest doing a 50% water change. As long as you have detectable ammonia you are fine I wouldn't add anymore until it goes to 0. Once your test kit shows it as 0 or close to it you should add a little bit of ammonia to keep your ammonia eating bacteria from starving but not so much that it pushes you past about .5 ppm.

Give a couple more weeks, mine did the same thing and then finally dropped from over 80 down to say 10ppm. A 1 week cycle is pretty short, it will probably take about a month atleast for the whole thing to completely cycle

If you've only been cycling for 1 week and your ammonia levels haven't dropped to almost 0 yet you've still got a ways to go. I wouldn't worry about your nitrate levels since you don't have any fish in the tank, anything under like 200 ppm probably won't effect your cycle. You'll just have to do a very large water change when your cycle is done to get them down below 40 ppm so you can safely put fish in. The nitrates are probably just being produced by the nitrite eating bacteria but it's also possible that your tap water has nitrates in it, I'd check that just to be sure.

Establishing the nitrite phase of the cycle takes about twice as long as establishing the ammonia phase of the cycle. Expect something like 12 days, more or less for the ammonia to go down. Then twice that long for the nitrites to go down. roughly, your milage may vary.
