I recently bought a new 5 gallon hex for one of my
betta girls (strange to call her a "girl" when she's bigger than both the boys) and it came with a whisper filter. I got the tank set up, live plants,
driftwood, a large chunk of filter media from another tank, let it run for a few days, tested, and
ammonia 0,
nitrite 0,
nitrate around 5. Anyways, the other day it just stopped working for no apparent reason. I tried unplugging it and plugging it back in, different plugs, taking it apart (which yielded nothing, they don't really come apart). And ultimately just couldn't get it to work. Luckily, I had a sponge filter lying around, so I went ahead and put it in the tank, as my betta had a small amount of finrot and I was medicating the tank. I wanted there to at least be some filtration. So, I have a few questions...
1. Since I only have the sponge filter in there, is there any way for me to save my cycle or do I just need to purchase a new one ASAP and put the old filter media in it?
2. What filters would people recommend for a 5G hex?
