Large water changes without cycling

[Luke]

Hey all,

Due to stupidity on my part (read: over-feeding), I now have a problem with high nitrates in my tank (10 gallon nano; Fluval 3 filter with floss; appr. 15 pound live rock with appr. 2 inch live crushed coral bed). The question I have is: how often can I do relatively large water changes (40-50%) to lower my nitrates without cycling my tank again? Any help would be greatly appreciated; thank you in advance.
