That's interesting Corriewf. In my tank when ever anything goes out of whack they and the stars will usually let me know before I can get around to testing. I'd love to see something backing this up.
Natonga I'd ditch the c.c. and the filter material if you want a reef. Most of the corals and as far as I know all the anemonies are pretty picky about water quality. Run your canister empty and go to home depot etc and get some play sand. That will really help out your water quality in the long term. I'd advise letting you tank get very well established prior to adding an anemone ," give it 8 months to a year." The don't do very well in new set ups you might also want to try some soft or even sps species before taking the anemone plunge. Even the easy ones are really pretty picky and I'd have to agree with O.G. and not add an anemone . As a matter of fact I'd also advise extreme caution with any of the corals and their kin as long as you have the crushed coral. The only ones I know of that would stand much of a chance would be the shrooms.
You could do all the critters you want with c.c. and filter materials but, it would take a LOT of chemicals and filters to keep your water quality good. In the long term it would save you a bunch of money and time if you would change a few minor issues with your set up before your tank gets too far along.
HTH
I love anemonies too I understand
