I agree. That Red mushroom fully extended at the same level at the Gigantea is not a good sign for the long term health of this very light intensive requiring anemone (like right under the 250 W DE MH).Doesn't look like there is enough light in the tank for him. When I see mushrooms and palys high on the rocks - that is a low light tank.
I purchased this Carpet on 9-28-2012 and was at the bottom of the tank until I added my live rock which was on 10-13-2012 at which point I put him where you find in the pictures he didn't move there.. Since he has been that close to the light source I have seen the color you see him gaining and has begun to eat as I stated.. I have two 1400 gph ph but they were just too much for my 75 gallon so I took them out and have a koralia 450 I know it isnt enough flow per but trust me the 1400 gph was way to powerful.. As for lighting I have 4 T5 54 Watts lights two are 12000 k and 1- Purple and 1- Actinic.. Of course blue lights also.. Tell me your thoughts On what I should do? As for my nutrients 5.0 Nitrates and Phosphate .25 I do run a 30 gallon Refugium and a protein skimmer.. Was having a cyano problem but I have seen it declining lately and Phosphate was at 2.0 at that time.. Please let me know what you think... ThanksI agree.

Look at my other anemones in the tank I dont by the mushroom story I've seen mushrooms expand VERY large under MH and not shrink... Let me know what the pictures tell you?Excepts when I was very new 25 years or so ago, I have always use MH light. T5 is a lit better than the old VHO tubes, mainly due to the small bulbs which can be fitted with great reflectors and get all the light generated down to the aquarium.
T5 bulbs need to be change frequently. Older T5 light bulbs put out much less light than the new ones. Good individual reflector for each bulb really help, it at least double the amount of light by direct everything down to the water.
Not using it, I am not familiar with the terminology. Does it mean that you have the total of 212 W of T5 lights on the tank? For new bulbs, MH and T5 likely have about the same efficiency Most of the DE HM have great reflectors while not all T5 set up have good reflectors.
If you have total of 4X54 W (total of 212 Watts) on the tank and good reflectors, and diligently change you bulbs, you likely have enough light. However, that red mushroom you have in the tank will deflated and wilt under this amount of light. This cause me to think your light is too weak.

I have wavepoint light fixture.. I will try again with the two PH I have..what brand/fixture light do you have? also as for flow I have 2 tunze's that put 1800gph in my 75 gal. and still wouldn't mind a little more, alot depends on placement.
