Aptasia in sump

[EmilyB]

I have tons of aiptasia in the sump. Fortunately, I have none in the main tank, I have a Red Sea Golden Butterfly and some peppermints.

I've thought about eradicating them but I figure as long as I have control up top, they are probably providing some sort of filtration service. Given they live in the compartment right under the overflow, I think they like flow.
