how much is 'moderate flow' in 20 gal tank?

[csail777]

Only 8 months into a small 20 gallon salt tank with 2 ocellaris and a blck & white damsel. Added a condy a month ago, and finally added Nicrew 25w light & glass top (to replace standard lid I used for fresh) and Aqueon 500 gph power head along w/another condy. (Bubble tip on the way - haven't been able to get at local stores) I've been reading and reading, and know the 'cautions' of the condy, but I love them while waiting on a larger bubble tip. Issues: the nems seem to hate the power head! Smaller condy hid in an artifical plant - and now I cannot find her at all!! (filters are covered) and larger one seems "about to blow away" no matter where i direct the flow! Is my light good enough? (use the sunreise/sunstet option) Suggestions?

The anemones will move to find a spot that is good for them, but you should not keep adjusting the flow to try to make it happy, you are inadvertently causing it to move again.
