Ok, I got a good question... need to know if anyone has done this.... I have a tank that is cycled and only has water, HOB, and a heater in it.... Thats it, no substrate, no nothing..... I want to switch to a sponge filter, and dont have any that are already cycled that I can pull away.... So i got a new sponge.... Like I said, the water is perfect right now, Nitrate 10ppm, 0 nitrite, 0 ammonia.... but if I change to a new sponge and remove the HOB will i have a spike????? cause there will be no beneficial bacteria in the filter..... or will the already stable water be good enough??
Who has done it, who will gurrantee it, cause I dont want to do it unless I get 100% sure answer... I have my breeding apistos in there!
