Zoanthid/paly health question

[Worleyxxx]

So I've been looking around trying to find the answer to this but nothing I've found seems to be real helpful at my direct issue. I've noticed obed the past few weeks two of my frags have begun to shorten or lose their lashes all together. My pink kraks have lost them quicker and most severe. But they have pretty decent growth. In the same time period the lashes have gone they've got three new polyps fully formed (little over a month). Could this be a case of high nutrient levels? Nothing I've tested for have me any real concern but my phosphates were a little higher than I want. .25ppm started (gfo this past weekend). Everything else in the tank seems to do fine with good polyp extension and lashes. One of my Utter Chaos' (other frag that's lost lashes) has bleached quite a bit over the last month but again has good growth. It bleached both on the bottom of the tank and 3/4 up ( had two separate frags). I can upload photos of my pink kraks when I get home so you can see a before and after shot. Any tips would be appreciated...again they're growing so I don't think they're in any danger but a polyp with lashes is more appealing to me haha

Here's a before and after pic, there's another polyp on the backside not photographed.

They look more like they r shrinking to me. Normally to much light or to low of nutrient levels. Also can be to much flow. This is my personal exsperiance.

Hmmm that's interesting, the tank is fairly young only around 4 months so nutrient levels may be the cause. I suppose the flow could be an issue but the other corals in the tank look fine and have long lashes. I'm running a 6 bulb t5 so maybe I should cut back the light exposure or try just running three bulbs for now. It bugs me the my expensive corals are the ones doing this for whatever reason....why can't it happen to my eagle eyes instead ha. Honestly I'm up to try anything as long as my bubble tip doesn't move around too much...seems happy where he's at and so am I.

Well the expensive coral r expensive for a reason. They tend not to be as hardy as the common stuff. There for less to pass around keeps the prices high.

What's the light schedual on what size tank?

My actinics (3 bulbs) come on at 8am and the remaining whites come on at 9, the whites go off at 5pm and the actinics go off at 6. Then the moonlight LEDs that line the unit come on until 8. It's a 48in 6 bulb fixture over a 75 gal. (48.5x 18.5x 21.125) I'm really not a fan of the bulbs I have and would prefer more of a blue spectrum opposed to white but I haven't gotten around to getting any new bulbs.

Not right now, just carbon and gfo in some phosban reactors coupled with an eshopps snow cone skimmer (I forget the exact model).
