Tips of Goniopora turning white

Any thoughts?
All params are ideal

Goniopora are a photosynthetic coral so they derive some of their nutritional requirements from light. This is done through a symbiotic relationship with dinoflagellates called zooxanthellae that live in the flesh of the coral. The dinoflagellates are actually the photosynthetic organism and the Goniopora colony derives nutrients off of the byproducts of the dinoflagellates’ photosynthetic process. Zooxanthellae is usually brown in color and the coral tightly regulates the population living in its flesh. Too little light will cause the coral to turn brown in color.
I would not recommend blasting Goniopora with a lot of light. I don’t think there are a lot of advantages to doing so. If you start to see the coral starting to turn lighter and bleach out, it is likely the result of high lighting intensity. When in doubt, favor lower lighting intensities until it is clear that the coral is demanding more.
One mistake I think some reef keepers make is providing them too much flow. If you have a powerhead blowing right at Goniopora from short range, it may kill off some of the tissue at that point of contact and cause a chain reaction to the rest of the colony.
Goniopora appreciate low to medium flow, but preferably with some randomness to it. That way you will get that gentle waving motion which helps keep the coral clean and brings food past the colony. If you see the tentacles violently thrashing about, that is probably too much flow and it would benefit from being relocated to a more calm section of the tank.
Lack of food is a big issue with these coral and there are two types of food to provide Goniopora. The first is liquid amino acids. In short, they are simple organic compounds that play a major role in building proteins as well as other biological functions at the cellular level. Corals regularly take in available amino acids from the water column so it is easy to provide them with adequate quantities by broadcast feeding an amino acid solution.
The second type of food I like are dry powdered plankton. There are several different types on the market.
The general consensus with these is to keep Phosphate levels around .05 ppm and Nitrate levels between 10-20 ppm. This is a safe zone that not too many people will dispute. If you need a recommendation there you go.

Thank you. I felt like I was pretty dialed in but maybe I am overlooking something. Too much flow, too much light, not sure.

First I want to thank you for all the advice you've sent my way over the last several months.
I was wondering what you believe in terms of coral Warfare. Because there is the possibility that GSP on the right is touching the ghani every once in a while.
I know some people say that GSP cannot participate in Coral Warfare or sting other corals. But I'm not sure if that is true or not. Either way I have moved that ghani over a little I don't think it's getting too much flow but it is mostly unidirectional it is tough getting the flow just right. The the lighting I think is good but I guess I can't tell without measuring it. I am feeding phyto everyday and reef energy every other day and manganese and iron once a week. I'm starting oyster feast soon. My big problem though maybe this is ULN do to my algae scrubber. I thought I was feeding enough to make up for it. I guess time will tell but I sure don't want to lose this particular Raspberry ghani. I really like it.

Sorry to ramble. So what do you think about GSP and possible Coral Warfare here?

I dont believe GSP is of any threat and for feeding - Goniopora have to be fed and fed a lot.
Goniopora do not put on dramatic feeding displays like some large polyp stony corals. In fact, they seem to shy away from contact rather than aggressively trying to capture food. They have this “pogo hopper” motion to their polyps when food is introduced. Liquid amino acids. In short, they are simple organic compounds that play a major role in building proteins as well as other biological functions at the cellular level. Corals regularly take in available amino acids from the water column so it is easy to provide them with adequate quantities by broadcast feeding an amino acid solution.
Also, try dry powdered plankton. There are several different types on the market and I recommend to mix a couple of them up mix when it is feeding time, and make a cloudy solution with them to broadcast feed over the Goniopora colonies. best is to completely turn off the pumps so that nothing blows away in the current and then spray a cloud of food over each colony with a turkey baster. The particles should be fine enough that the fish won’t come and harass the coral, but even if they do, you can apply another dusting after a few minutes. After about 15-20 min - start the pumps back up.
