So I attempted to cycle my 2.5 gallon tank using a red sea nano filter filled with some biomax pellets and a cut to fit polytech pad and carbon pad. I wasent sure if it would work or not but I believe I was successful....
For the last two weeks since I set the filter up, I would have to do a 100% change every two days. My fish would stress horribly and I would test the ammonia levels. The ammonia would spike so I would change the water. My last water change was thursday of last week.
I figured that my fish would stress like normal and I would have to do a water change but to my surprise he remained completely healthy. So today decided to test the water and sure enough my ammonia and nitrite levels were 0. My nitrate levels I can estimate were somewhere between .1ppm and .3ppm since the color was darker than the 0ppm reading and lighter than the .5ppm reading.
So here is my question. If my tank did indeed cycle, what will my new water change regiment look like? 50% once a week? Has anyone else successfully cycled a 2.5 gallon and held the cycle? Im afraid that if I change the water too much I may loose the cycle. With the tank being so small it may be impossible to hold the cycle but im hoping the added biomax provided enough surface area to do so. What do you guys think?
