Cycled my tank in about a week, and no hitch hikers so far!
Cycled the tank in about a week, but it was massive for my 14g cube. Purchasing the smaller one :)
My tank appears to cycling beautifully. I needed seeing bacteria and this has been a life saver.
Additionally, I put the filter into a nylon stocking in an effort to restrict snails. Well see if it works.
This works so well, do not hesitate to buy this, you will not regret it, it so quickly helped us cycle our tank for our axolotyl.
The filter didn't work for my tank. I did a fishless cycle using fish food. I waited for a couple weeks and saw no difference or change in 2ppm ammonia, zero nitrites, and zero nitrates. I decided to use dr. Tims cycle and cycled in 5 days.
We don't recommend fishless cycles. Our experience is that they have the potential to cause many problems.
There must be something odd going on in this tank, since ammonia should be either going up or down over a 2 week period. It should never be static. If the filter isn't working, it should go up. If it is working, it should go down. When it does neither, it suggests that something isn't right.
Our base recommendations are: Use live animals to produce the ammonia for the filter. Do NOT use ammonia neutralizing products, such as Prime (even when changing water). Use a basic chlorine remover if chlorine is a concern when changing water. Finally, do not feed too heavily while waiting for the nitrifying bacteria to build to the levels your bio-load needs.
