I apologize if I came off harsh, and I’m further sorry for the advice we’re sharing. About a year ago, I had a 6 month old 13 gallon tank that was doing really well. I tried an anemone, even though I was warned my tank was probably not mature enough yet, even though my clam was thriving (each tank is different). I tried anyway, and almost killed the poor nem. I eventually took him back, because I’d rather it survive, even if not in my tank. I started a 40 breeder, waited another 6 months, and this time I had coralline growing out of control, I had my parameters much more consistently in check, and my new nem is doing great!
In order to get your tank to a place that it’s set up for a nem to thrive, you’re going to have to make a lot of great changes (lights, flow, water parameters, etc). These changes are only going to stress out the anemone further. If it’s already struggling, it just seems fairest to give it the best chance you can now, and try again later.
This is only my $0.02 from my own personal experience, and there might be others on here who disagree, that might believe it has a better chance maturing alongside your tank, and you can weigh those opinions as well. Again, good luck, whatever you decide. I’m hoping for the best for you and your nem
Also, I think carbonate hardness is the measure of alkalinity. So they’re interchangeable. You might also see dKh referenced. Same thing.
