I have not read them yet, maybe you can Al and summarize them
for us

	SPS Small Polyped Scleractinians - Sometimes known as Small Polyped Stony corals. These are hard corals that have extremely small polyps. They are typically on the difficult side and require Metal Halide lighting or dense Power Compact or T5 arrays. These corals are prized for their rareness and ability to be easily fragged into multiple colonies.

Most, if not all, eat bacteria for starters, then it varies with the species we are talking about. Some don't require food at all, and acquire all their nutients via photosynthesis and amino acid absortion directly from the water column.

that has to be the most boring read of my life, i rather retake my physical chem class!!

but from the first article Eric Borneman states
"Coral reef food sources, then, are largely produced by the ocean. Bacteria, detritus, phytoplankton, zooplankton, small benthic fauna, mucus, and dissolved organic and inorganic material of various types and sizes are what comprise the majority of food on a coral reef"

as for nutrients like phosphate and nitrate...
"Bacteria and phytoplankton are also extremely proficient at removing this material. All these organisms are quite valuable to our captive reef communities. They not only "purify" water by the utilization of nutrients, but also are all part of a beneficial food web, both in coral reefs and in aquariums."

but he also claims that the highly efficent proteinskimmers now will remove pretty much all the bacteria and plankton in our systems....how true is that statement?
He "realize this is contrary to the advice that many others may offer, and it may sound like a reversal of thought and progression over the past year's trends towards increasingly efficient protein skimmers. However, I feel today's powerful skimmers are certainly able to provide adequate nutrient removal to maintain aquariums with very low nutrient levels without running "around the clock.""

and according to Eric, the best water to keep your tank at a baseline is with routine waterchanges. So does that mean less skimming and more water changes??

"We may never be able to duplicate the coral reef, but we can get closer and closer as we learn more about closed systems and the natural communities."

thats the basic idea i got out of the first article

wow Jackson, where can I buy your book. It must be filled with such clever observations as "Eric Borneman is an @$$." Clearly you have a grasp of the subject far surpassing any of us mere mortals. Are you a politician by any chance, because I'm pretty sure you just reitterated what I said about tank parameters as if I was wrong in saying the same.

So my next question is....what gives sps their color? Is it their natural tissue color? Since too much nutrients means more zooxanthellae, so does the zooxanthellae actually mask their true colors?

i lost that article after the 3rd sentence ill stick on wat u guys say

No idea what will color them up in general but at least I observed that with changing environment, their color will keep on changing. I have couple frags from JHale for which the polyps body is very brown and the tips are very green when I got them. I was told that they are purple digitdatz. After a couple weeks, brown turns light purple and green turns to lighter green. Couple months later, the polyps body turns clear and the tips are same color. There are a lot of skeleton growth but the poylps are not as dense as before. Most recently, the body of the polyps turn to brown again. So far, I have seen it in purple for a period of two three months which fit its name while all other times, its color-changes never match its name.

So I assume if we alter or deviate from the environment they live in, they will change color and may( or may not due to health issue) stay in that color we like. The color may not be the most natural or heathly though. So I have witnessed color changes but not color ups. Hope some can share thier experience.

From my own, I feel temperature changes cause color changes greatly.

i belive he rich no's his stuff.... look @ his tank, he is doing something right ....

Observations...

High water flow- Removes waste from corals, brings bacteria from surrounding areas (LR, fish poop) (food)

Lighting- Proper lighting in the spectrums that enhance growth and color. Corals are also photosynthetic. Lighting period for different types of corals and depths at which they are collected contribute to color of same. Lighting Intensity contributes highly to color and growth (PAR level for you sci-fi guys)

Food- corals eat. SPS eat bacteria for the most part. Some can even eat cyclopseze (Observed by many including myself) Golden pearls and other crap. SPS do not eat fish poop but fish poop has bacterial matter in it which the corals do eat. Hence, feed your fish

Chemical media- Carbon reduces tannins in water improving water clarity which allows higher light visiblity for corals. This is why if you use carbon after not doing so for long periods of time, lighting period should be adjusted unless other mechanical/chemical means were employed during same period.

Mechanical filtration- Mechanical filtration can consist of simple filter floss (not recommended for reefs unless consistently replaced), micron filter bags, container filters (hate them, nitrate factories..) and above all the Infamous Big Protein skimmer. The most important piece of equipment for a reef besides lighting. Removes Tannins, organic material and fish waste before breaking down inside the aquarium and causing higher nitrites and nitrate. All of these MUST be cleaned on a regular schedule.

Undoubtably not the only things that contribute to a successful reef but also help growth and color in SPS corals. The key is to balance and consistent parameters.

Chemical additives - Calcium, magnesium, Iodine, Potassium and other additives. Of all of these, calcium addition is the most important. But again that is easier said than done. Most salt mixes will give you "close" to proper levels of calcium and magnesium for tank inhabitants but most must be buffered for correct "optimum" levels for coral growth and color. Once again, it is the balance of these that determine coral health.

Tank parameters - Everyone will have different params just because we all never use the same stuff (equip, salt, or water) at the same time from the same sources. The obvious part of parameters is one constant basis..Natural seawater.. It is used as a baseline for coral water conditions in the wild (open Oceans). Alk, calcium and mag levels will be elevated in home aquaria for the simple fact is we suck at keeping our tanks maintained to Ocean levels. WE play with our tanks to much!!

We also want elevated levels of growth, Coloring up of corals and Polyp extension the lenth of our fingers. There are also different theories as to how to get to these areas in our tanks. Zeovit, DSB, Low nutrient, Bare Bottom, Surge tanks, Heavy Bio-load (Fish), Low Bio-load (no fish).. blah blah blah...

Correct husbandry should be paramount to anything else. If you have hair algae in your tank you have problems. If you have more detritus in your tank than sand, your tank sucks... If all your fish have ich and die then you suck.. and so on.

DO water changes (replaces calcium, mag, balance alk removes waste and replenishes trace elements), monitor the coral health and other inhabitants. Changes in animal health also are indicators for coral health and vice versa. Get the right equipment for your tank. If you can only afford a Seaclown then you need to keep damsels not a reef. Ask questions, it helps..

What does all of this have to do with coloring up SPS ? Nothing and Everything... Cant have coral color if they cant survive long enough to COLOR UP. SPS can start out in one persons tank Green or Brown and turn blue in anothers. Phosphate can do that, high nitrate levels can do that and starved corals can do that.

Oh yeah.. Rich has been one of the few people not only on this board but in the hobby that has successfully kept and propogated SPS corals. He has set the bar high earning himself the name SPS Pimp. Like I have always said, not everyone who has written a book knows everything there is to know about the hobby and not everyone that has NOT written a book should have their ideas shunned. I have read more than a few that need to research thier facts again... I will not mention names.
