My crowntail, Spike, had passed away. He was bright/active the entire time, just suddenly kicked the bucket with no outward signs of issues. So I purchased a new betta, a double tail dubbed GoJo.
Now I'm suddenly having issues. This tank is supposed to be cycled. Yet everyday I'm being forced to do a 100% water change because I am getting a reading of 1ppm ammonia. My betta is likely slowly dying and I can't figure out wtf is happening!
I was thinking that maybe there was waste trapped inside my sand and when the sand was disturbed the ammonia was released? As par the idea, I did atleast 5 100% water changes/vacuums. I disturbed the sand as much as possible to make sure I am removing all waste possible. I couldn't find anymore waste when vacuuming on my last water change.
I scrubbed down the walls, rinsed decor in hot HOT water, scrubbed down the housing of my filter. I've rinsed my media in decholrinated water. Added more media incase that somehow whatever the betta was producing didn't have enough room in the original media.
I just have no idea what is going on/what more I can do.
Tank has been running with no prior issues for 5 years
HOB filter rated for 10 gallons/baffled with a plastic water bottle
Marineland filter pad for sponge media
live plants: anacharis, duckweed/slavina
gator head from wally world(was purchased 2 years ago)
I've been doing daily 100% water changes, treating with Prime every time. Yet I am getting a reading of 1ppm ammonia everyday. The only inhabitant is my double tail betta.
