sps question

[Xclusive Reef]

I read somewhere online that when getting SPS for a tank its best to get all the sps you want at once like 1 inch each and it will do better than introducing sps when other corals (lps) are already in the tank. Whats your opinion on this ?i will see if i can find the article.

I actually found the article.

" It takes about 5 to 6 months for Acropora species to regain their normal growth rates after being added to an aquarium. At times a healthy system has an additional Acro added and all the others die from polyp bail out or what people refer to as RTD (rapid tissue degeneration) and a whole tank of acros can be wiped out within a matter of hours. They are unsure why this happens, but it would probably be a good idea to have all the Acros you are going to want, and put them together at once while they are still young. "

I must have super acros or a bullet proof tank cuz I add as I get and have yet to have rtn or stn. That link doesn't work for me.

I don't know of any scientific data that indicates it's better to add all of your SPS corals at one time. If your going to have a problem, it's going to occur no matter what ,or how much of, corals you add to your tank. Best husbandry practices assures you a healthy and vibrant reef tank

I have never found that to be true. Regardless of adding at once or spread out, It shouldn't make any difference from a health standpoint & growth rate standpoint.

With dipping and quarantine it's not a big deal, but the reason for not adding new SPS to an established SPS tank is to mitigate the risk of introducing an unhealthy piece. RTN is very much real (I've always seen this as "Rapid Tissue Necrosis"... not sure where they picked up RTD), and if your new frag let's tissue go (which is not that uncommon with maricultured and wild pieces) then it could destroy your whole tank (the necrotic tissue touching an otherwise healthy Acropora can cause a chain reaction where the healthy ones also shed their tissue). So it's really a precautionary issue since Acropora can be finicky and if one RTN's many more may follow.

But no, I do not think there is an actual health or growth issue beyond trying to lessen the risk of a new frag triggering an RTN event with your existing established colonies.

Don't put anything that looks questionable in your display tank.

IMO, there is always a risk anytime you ad something to an existing environment. That being said it seems to me that the mathematical odds are the same regardless of whether they are added all at once or one at a time. Also seems logical that the more sources used the higher the odds of some sort of contamination.
