Clown is trying to bury new carpet anemone

[DanG]

So I snagged a really nice green carpet anemone from my LFS yesterday. Got him into the tank, killed my white LED's, turned the blues down to 10%, killed all the pumps except the return so he's be able to attach his foot in the sand. Before I went to bed last night I turned on the smallest PH in the tank, woke up and all was good, he's attached his foot to the bottom. I plugged my vortech back in, everything is good.

I just walked by the tank a couple of minutes ago and my maroon clown is digging around and dumping the sand on top of the anemone.

I haven't turned the vortech back up, it's still on low. I did try cranking it up to max but with where it's situated, it won't blow the sand off.

Should I use my WC hose to suck the sand off and just replace the water/sand over on the other side of the tank, blow it off with a PH or just leave it be?
