So can nitrates be too low? My tank is a mixed reef with a some SPS, LPS, anemones, clams, fish, inverts, etc. Is it ok for there to be undetectable nitrates or can that be bad for some animals ...?

I think you're going to get mixed answers on this one depending on what exactly you are trying to keep (sps/lps, etc). Personally, in my tank which is mostly LPS with some softies and SPS thrown in, I've noticed a pretty dramatic increase in coloration and growth when I raised my nitrates from 0 to only 2-3 ppm. This is purely anecdotal, though, so I cannot say for sure if that is what led to the sudden increase.

Our hobbyist test kits aren't all that precise, so a reading of 0 on a nitrate test kit tells us very little, unfortunately. So "undetectable" could mean a level that's fine, or a level that's too low. Once the kits get down towards their detection limits, watching the animals is a lot more effective, IMO.

my Red Sea test kit says .5 ppm. I had a HA problem which I just got under control so I don't want that to start up again ...

I feed roti feast, coral smoothie & phyco pure 3X/week and Fuel trace elements 2x/week ...

0.5 ppm is high than natural ocean levels, but should be fine. I don't think it'll be a problem at all.

ok, thx. I've tried kalk paste on a small patch of bryopsis and it seems to work. So I think for the time being I'll stick with the Red Sea treatment for the HA & kalk paste for bryopsis ...

That sounds like a good approach to me. Good luck!
