Aprox. Time to Cycle Tank without adding bacteria from Bottle

[Goldfish4EVER]

Hi!
I'm currently cycling a tank, but I'm wondering around how many weeks/month it will take without adding bacteria from bottle? I've heard it can take around 4-8 weeks.

My experience was 5 to 6 weeks. I followed the method on our site.

I'd say that's about right 4-8 weeks... Mine took around 5-6

Some bottled bacteria products speed up a cycle, some do nothing. If you want to try one, look at Dr Tim's One & Only or Tetra Safe Start as those are known to contain the correct species of nitrite eaters.

using a simple dechlorinator and guppies at 80 degrees I think it was 21 to 24 days the last time I did it.
