I concur. I have them in my sump and overflows and, yes...in the display too. The sump and overflows get ambient room light only. If I'm not mistaken Aiptasia are aposymbiotic. I understand this to mean that they do not require light to survive. Consequently, depriving them of that is futile, IMO. Also, if that were the answer to eradicating these bastards, wouldn't that be documented and well known common knowledge by now? Seriously. I'm not trying to be a smart-ass....it's just a suggestion as per the discussion.
As stated above, I have Aiptasia problems also. (It's actually quite bad). My hope of eradication is increased flow, increased skimming and a refugium (read: increased nutrient export), and natural predation by way of a Tasseled Filefish. All this to come with pending upgrades. (I have at least one Peppermint, but he must be on strike ).

Again, not trying to be a smart-ass here. I share your pain as I have a plague problem with Aiptasia myself. Just saying that I'm not sure that depriving them of light is the answer. Wouldn't hurt to try, however, IMO.

Cheers,
