I have been wanting to start an sps nano for a while so I have been reading every thing possible about sps. Since I have been reading I'm going to post some stuff to maybe help others out with keeping their sps coral healthy and colorful. Their are many types of sps out their but I am going to talk to you about the general care for all or most of these corals. Sps coral that come out of the ocean and into your tank has a less success rate than sps colonies that have been in tanks and fraged for a while. Your best bet is to get them from a fellow reefer, because you know the care the coral got is probably better then getting it from a dealer. Its also a good idea(if you can) is look at the mother colony to inspect it(make sure its healthy, colorful, parasites, STN, RTN, etc). Of course you will also want to inspect the frag you are going to buy also, mostly for the same things you would on the mother colony, make sure their are no bugs on the frag though. Also look closely at the base of frag for any signs of RTN or STN. Speaking of these little parasite(which their are many), its a good idea to dip your coral before putting them in your dt. A lot of people I have talked to say to use Coral RX. This kills Acropora Eating Flatworms (AEFW), Montipora Eating Nudibranchs, Bristleworms, Zoanthid Eating Spiders, Red Flatworms. CoralRX is also said to help prevent Filamentous Hair Algae, Rapid Tissue Necrosis (RTN), Slow Tissue Necrosis (STN), Bacterial Infections and much more. After the dip it wouldn't be a bad idea to corentien these corals to watch for any signs of parasites or other things such as RTN and other diseases. Now lets talk about what kind of equipment is a must have for keeping happy healthy sps coral. SPS coral has been kept under mh t5s for quite some time. LED lighting is newer to the reef hobby so its hard to say what the long term effects will be, if you keep sps under them. But yes, People are trying sps under LEDs quite successful, so if you want to be one of them, by all means have at it. VHO can also be used, but I would not recommend it as a main lighting source. Good light bulbs for these systems are also a major concern. If you dint have good quality light bulbs, your sps might not do as well as they would under good quality light bulbs(ATI, Giesemann,KZ korallen, XM, Phoenix, and ushio are all pretty good light brands). Placement is very important also, different types of sps grow different some are bushy, some tabling,etc so make sure you pick a spot the will like. Now its very important to maintain good water quality so make sure you have a good protein skimmer at the least. Some Good protein skimmers(their are many different types of skimmers) are Reef octopus, precision marine,bubble Magus, and eshopps are all decent skimmers. I would recommend one that is rated for at least twice the size of your tank volume. A fuge is also strongly recommended but their are sps dominate reef tanks that do not have them. Know a nice aquarium controller (digital aquatics reef keeper controller, and Neptune systems controllers are good, and a reasonable price) would be nice, just to make things easier but you do not need one to run a nice sps reef. I would say an ATO is almost needed so your salt level does not swing much. A chiller is also a nice thing to have (mainly if you have halides or live in a hot environment) so your water will stay at a constant temp, but if you live in a cooler area of the world I see no need to get a chiller. A Dosing system, or a reactor is also a good investment (you will probably need one if you have a good amount of sps, for calcium and such) to keep calcium, alk, and mag in check. A good range to shoot for is calcium 400~450, alk 8~10 dkh, and mag 1450~1500 is a good range. You also want your phos. to be as close to zero as you can get. Your ph should be around 8.5. Some people do zeovit (which I know nothing about so I'm not going to get on that subject). It would also be a good idea to do 10-25 % weekly water changes to maintain good water conditions for your sps. Flow is also another factor in an sps dominate tank. You need LOTS of flow to maintain healthy sps(generally the more flow the better). The directions of the currents should be different, to try to eliminate dead spots in the tank and also to make sure all sps get flow. Diseases such as RTN can occur if their is not enough flow(usually its around the base of the coral first). Some people also feed their sps food(or get fish for fish poop to feed them). Some people also get phyto or oyster eggs to feed them. I do not believe its necessary to feed sps, but some people have reported better coloring and growth when feeding them(that decision will be left up to the owner). The last thing is to sit back and watch your sps grow!!!!! If i missed anything plz feel free to add.
