Why is SPS so hard?

To each their own advice. I dropped LED's years ago because I went through what you're doing. Dimmable ATI Sunpower T5's, 9 hr light cycle, 36" wide eight bulb unit 16" above the tank. P04, N03, if they are at low levels SPS will still grow. You need more flow. Also, dump the GFO and carbon, my tank has been running without for 2 years and it was only after getting rid of this would my SPS do well. In fact, they are growing like weeds.

I didn't read the whole thread, sorry. My pH dips to 7.4 at night, no ill effects. CA reactor and kalk topoff constantly. 90g tank, 30g sump, 80 deg F, alk at 11DKh or so, Ca at 450+, Mg at 1200, if you're using Red Sea Coral Pro get rid of it. The best salt I've found is the German Reef Pro salt from BRS.

I know this flies in the face of a lot of advice you've gotten. However, after I stopped listening to everyone else and just kept the tank stable with good flow, lighting, and consistent water changes, everything came around.

Best of luck

My tank has been running for a year now. Haven't lost any corals or fish in 11 months (not including SPS). But I can't keep any SPS successfully. Why is it so hard and what am I doing wrong?

I have numerous other corals. 20+ different Zoa's, mushrooms, favias, acans and I haven't lost anything but SPS corals in the 11 months.

I tried birdnest, acros, and monti's. None have survived more than 3 weeks. They either get STN or RTN.

if anyone has any tips that can help me be successful at SPS I will greatly appreciate them!

Through 10+ years trial and error, I've found swings in parameters will stress any SPS out. Steady Alk is key. You will get great color with a little nitrate. I aim for nothing over 10 ppm, though I did see crazy coloring around 40... Just tons of algae blooming...lol nobody mentioned PO4 that I saw. I wouldn't keep that at 0 either. Anything from .02-.1 will suffice. Check source water, make sure there is minimal swing. Salinity shouldn't swing either. Stable water quality is key. Make sure nothing can reach it, sweepers from LPS and whatnot. Check flow, yes. If you have 90 degree bends in the return, it typically reduces flow to that of the next foot, with 45 degree bends by half a foot respectfully. LED's are tough on SPS, hands down. It takes time to acclimate them. What is the placement of the coral in retrospect to light and flow? And lastly, what is your dipping regimen? There are many checks and balances in the hobby, and SPS are the pinnacle of them. To pinpoint without seeing the system and corals first hand is tough, and every system is different.
 
Well, allboutthe305, you have certainly brought this crowd to it’s collective level of wisdom. You also may now realize that for every ten respondents there are at least ten different opinions. How do you chose which to follow? Let me give you my experience from 70 years in the hobby/business. When people ask me, “How did you learn all that you know about keeping aquariums?” My answer is the same every time, “I got my degree in Aquariology 101 from the School of Hard Knocks”.

In order to learn how to keep a successful SW aquarium of any kind you must research everything. Next comes trial and error. They go together you know. Next is observation. I mean not just looking into you aquarium but looking at it meaningfully. Looking for changes in behavior, color, texture, growth or lack of it, feeding or lack of it, feeding the RIGHT food items multiple times a day, testing water parameters often, doing water changes, using only the purist water from your own RO/DI unit, and on and on. You see, there is very much to learn. It is impossible to list it all here. It’s also impossible to take everyone’s advice. What is possible, is to read, sort through the cloudy waters of advice, make a choice and follow it. Compare results with your previous experience and move forward.

Here’s some observations about SPS I’ve learned over the last 40 years of doing SW exclusively...

SPS corals are the most challenging of the group. They like stability in water parameters, lighting type and schedule, they need lots of flow BUT not directed at them. When I get new corals in, a weekly event, I first dip them in Revive (a Two Little Fishes product), then let them rest and recuperate from whatever trauma they endured getting here for at least a week. All the while I continue with my scheduled water changes, supplement additions, general cleaning, etc. During this period I pay close attention to all my corals but especially to the new arrivals. If there polyps are not extending, I add some products from the Korralan-Zucht ZEOvit line of additives that SPS respond to. Once the polyps are out, I feed phytoplankton to the whole system in the appropriate dosage. SPS corals that don’t extend their polyps are not able to feed properly, therefore will decline in health. Yes, I know there are those out there that will tell you, you don’t need to feed corals that are photosynthetic. They get their energy from the symbiotic algae in their tissue. It’s true, they get SOME of their energy in this way. but, we are talking bringing a coral BACK to health from the trauma it has experienced getting to you.

I could go on and on... but you should be getting the idea that SPS corals are not impossible. You just need to continue to ask questions, read, observe and learn. You will unlock the doors to success along the way. Every successful reefer that I know has passed this way before you. If you are steadfast in your passion to learn, you too will one day be a successful reefer who will have a reef tank to envy.

You are on the right track! If you (or anyone reading this thread) have questions you’d like to direct to me personally, send a PM. It’s my preferred method of teaching because my response can be more directed toward your specific questions without the cloud of confusion.

Happy reefing,

Dick
 
for my birds nest i am running mp es w 10 vortech at 80% from 6am -9pm 9pm-6am at 30% and radion 15 wpro for lighting between cycle 0 to 80% . i alk i use 8.4 only 10.6 gal display with 3.4 sump cal i run lower 375 on avg. health not fixing it lol
 
Just wanted to add, I've been travelling all year and my tank went 22 weeks without a water change. My wife can't help much because of her MS, so just filter sock replacement, skimmer cleaning, and top-off water. My PO4 is at 6ppm and NO3 is off the charts. Got hair algae. My T5 bulbs are 3 years old. BUT... SPS still going strong. Still great colors.

And here's the kicker: while out of the country, my return pump failed and my tank fell below 65° for at least 48 hours. My wife was able to jury-rig an old Mag 5 and get the flow from the sump going again. One coral died. Just a reminder that you don't need textbook conditions to make it happen.

Hope your tank is doing OK. Sorry for raising the zombie thread.
