is it safe to buy berghia nudibranch if my nitrates and phosphates are somewhat high?

[Leon Gorani]

last time i tested my nitrates a week ago they were at 12 ppm and photosphates were .85 ppm from my hannah low tester. i have too many aptasia and i wanted to buy a bunch of berghia nudibranch to hopefully get rid of them. do i need to lower my levels of both so that the nudibranch’s can survive or will they be okay as is?
thanks.

I think they should be ok. I have tested phosphate as high as 1 (maybe higher values that weren't tested) in my Berghia cultures and not seen any effect. I do multiple water changes before harvest to try to get it down to 0.1-0.2 before they get transferred to a 'normal' environment, but I don't know if that is really necessary, as they tolerate an 80% water change fine.
