Question about nitrate, water changes

I got the API test kit that everyone is raving about. Much easier and faster and way more accurate than my previous liquid kit.

Anyways, here is my readings from my 10 gallon tank.
Temp: 79/80 degrees
PH: 7.6
Ammonia: 0
Nitrite: 0
Nitrate: 10

My question is this: are the nitrates okay? This is my first tank and as the numbers show, it's been cycled.

Also, how often should I be doing a water change? I have the 2 mollys, 2 plattys, 2 ottos in there. Plus, about 8 fry who I am hoping to adopt out soon.

Thanks!

Mom to three cats: Phantom the Klingon (Phantom for short), Patches (also called Crash and YOU LITTLE SNOT!), and Mooch (who pretty much lives up to her name), Flash (crowntail betta), Itsy and Bitsy (oto cat fish), Charlie (black molly), Spot (dalmation molly), Dusk and Sunrise (sunburst platties). All are raw fed

all looks good. nitrites are problem, but nitrates are much more mild form. 10 ppm is nothing to worry about and will be eliminated in you next water change. for that tank id do a weekly 25 percent change as it is fully stocked

I basically agree, though I would up the volume to 1/3 to 1/2 weekly. Provided your tap water parameters are reasonably close to the tank, this is fine. And it will result in even more stable water.

One coment on the API nitrate test; the instructions say to shake Regent #2 for 30 seconds before adding the drops to the test tube, but it should be shaken for 2 minutes. It frequently happens that the result will be much higher if the Regent #2 is not shaken for 2 minutes. [You might have even lower nitrates.]

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If youíre going to take it under your wing then youíre responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
