I'm just wondering if anyone knows if these are safe for bettas?
The fish expert at our local pet store (whose opinion I generally trust) pointed them out. I'm cycling a 5 gallon tank for my betta, and it's ALMOST ready but water params are too toxic to put him in yet, so he'll be in his 1.25 gallon bowl for now. Our tap water has ammonia, so his bowl has trace (0.15PPM) ammonia that I'm hoping the above media might help with...
I'm mostly just confirming that these can't leach anything into the water that will harm a betta. (box says just for freshwater - does not specify any particular kinds of fish). If it's not effective against ammonia, at least we tried.
So thoughts/opinions on the safety of it?
