xtlosx- one of your gigs gets pounded by an MP40 (hasn't moved since Feb) the other gets moved around a bit (with multiple MP40's on 'crest mode)hasn't moved in a month and you post that you "think the whole notion is overplayed"?
I'm confused please explain.
IMO/IME water flow is much more important to S. gigantea than (for example) Haddon's carpet anemone.
S. gigantea prefers water motion similar to what H. magnifica prefers.
I've had my gig for several years now in a high flow SPS type environment.
(One MP60 and two eductor capped returns with an Iwaki100RLT as my main pump).
There's a lot of water circulation and my gig loves it.
It's pretty common to have a non-reefkeeper or someone new to the hobby look at my aquarium and remark that there's NOT a lot of water flow in my aquarium. Nothing could be further from the truth.
I think water flow and lighting are much more important to gigantea than haddoni and neither species is a good "beginner's anemone".
My blue gig parked himself in front of a high flow area at first then a couple days later got low and into a low flow area with less light reaching it. I was concerned that the flow pushed it out of the light. And adjusted the flow but it hasn't moved. It's 550 flow from one side and 950 from the other in a 45. I fired up the 1650 with the other two but it was a ton of flow and it looked like the green had a hard time with it.

Mine seemed to do best in an area of alternating flow of a lot of water, but out of a big pipe. So, in other words, a lot of water but at a slower velocity. Modern wave makers that set up a standing wave in the tank would be perfect for gigs in my opinion.
I got my purple on one end of a 75 gal on the opposite end is a gyre set a 50% constant flow...on the side where the nem is ..another gyre set at 30% alternating pulse mode....when the left pulses it creates a nice surge above the nem..no "getting pounded"...more like alot of water moving it nicely back n forth...with a strong surge every so often..
I think some of the flow pictures I see with gigs on here are un-natural at best..
Is it possible for you to post a picture of the flow you provide for your Gigantea? I would love to see it. I alway try to find better way to do something. I often use Vortech. The most often configuration is to have two at opposite side at random flow. I like the flow meet just at or near where the anemone is. I often find that this is the best for both Gigantea and MagnificaI got my purple on one end of a 75 gal on the opposite end is a gyre set a 50% constant flow...on the side where the nem is ..another gyre set at 30% alternating pulse mode....when the left pulses it creates a nice surge above the nem..no "getting pounded"...more like alot of water moving it nicely back n forth...with a strong surge every so often..

I tried 3 times to post a video as an attachment ...and this damn site keeps kicking it out !!
