You're fine. No Hijack. I think the PE issue is something I have too, and I don't know its because of the angels - as I only have one genicanthus. I think that it is more likely to do with availability of nutrients, and the excess amount of light. I do not know what it is "normal" in nature, but my hunch is that those with a lot of polyp extension are stingy feeders and have a VLN tank. Just a hunch. At night, my PE is crazy.
Yes maybe because there are enough nutrients and light for the corals they don't feel the need to extend their polyps at day as mush as corals in ULN tanks. We are spoiling our corals with all the extra food.
I have 4 and an mp40, but no wxm, so not sure if flow is right. My tank is the same dimensions as yours, but can never get above 4.2 on my flow
4 MP40 in 425g is far, far too little flow for a great SPS tank IMO. Especially when it grows in. Those MP4o wont even barely reach the center of the 8' tank when placed on the ends. Of course this will look like I am trying to pitch our product, but my suggestion would be to place all four of those MP40 along the mid back wall, evenly, and then add at least two, if not four WAV pumps. Place them in the back corner, one up high, one mid tank, all the way to the back, and angle them to hit the front glass. At that point, you would have enough flow to last you for a long time. And the best part is that two WAV is still less than one MP40 and there is no additional power supplies to mess with or control box or wireless.
Thanks. Love this car. Need to replace it soon and sadly I will have to replace it with the M4 because the M3 is a sedan only.
MP 60 is a must and the Apex WAV have almost too much power
I am running six WAV right now. I am lazy cleaning them though so they probably are running like four. I like at least 30-40x turnover from powerheads in a big tank.
