Fishless Cycle Log


Sakura

FishlessCycleLog2011.png

Here's a graph I made with the numbers I got for ammonia, nitrite, and nitrate while doing a fishless cycle on my 55 gallon tank. It took about 45 days to complete the cycle. Below is the detailed log of how things went. :) Towards the end I supplemented with Microbe Lift products because I was getting nitrites showing up again. I'm not 100% sure whether or not the product made any difference, but it seems like it might have. I used pure ammonia from Ace Hardware store. Where it says "add ammonia", it was about 3/4 of a capful added. Towards the end of the cycle, I tried to push it a little by adding slightly more ammonia, and I think that's why the nitrites rose a little bit for a while.

Follow-up!

I've had the three fish for a week now. I tested for ammonia and nitrite every day, and never saw any cycle bump from adding the fish at all. The fishless cycle was a great success!
