This guy is giving you a data point. Real life, ups and downs have hit his tank and the stuff has not just over come, but flourished. That was my whole point - this is real and do not discount it. You can clearly see that he knows what he is doing or else he would not have legit acro colonies. He has not had "correct chemistries" or there would not cyano or algae. Embrace the opinion from a guy who has a tank beyond what 99% of other people do. If he credits this to the lights, then remember it and learn something from it. We are not talking about a guy with a 2 month old biocube with some boogers on frag plugs telling everybody that what he has is "the bomb" without any other experience to compare to.
Ty has never changed water - ever, so he says. T5s keep him ahead of the game, IMO. There is no awesome chemistry in his tank, just "good enough." This is another data point similar to this one. I do not really pay attention to my water parameters or care if they are all that stable - stuff thrives. None of these tanks have corals living in sewage, but I would doubt that any are perfect.
There are recipes for how to succeed with Acropora. Some people do not believe them... they want to believe a
BRS video instead. Ok, that was an overgeneralization, but you get the point. Lots of people today see an outlier or exception and think that they can make it work too... bet on the rule. The rule with exceptional Acropora tanks is best of the best lights... more people succeed with these than with inferior lights. While not inaccurate, saying that all things matter is a red herring... they do not matter in the same amount. This statement can sometimes give false hope to people who will never have perfect parameters and probably just change to better lights so that it does not matter. Lighting is by-far the most important.
Sometimes, we, as reefers, are blinded by our own stupidity - I am not calling anybody stupid or anything, just the hobby as a whole sometimes. It does not really matter WHY having alk near NSW is important, or WHY do MH/T5 just work, or WHY does 78 degrees seems to be best, etc. What matters is that they do... but we try and think too much instead of just doing what works. Don't think about why... pay attention to the many, many people who have the same story, will show you photos of their work and just do what they do. Why can get you into trouble - Why do we need IR spectrum - it is only in sunlight that lights these corals in nature and also in some other great artificial lighting, but I cannot see it, so why put it in a LED? ...only to find out that it is really important to help proteins process energy. Why do I need to use rock from the Ocean that has yielded great tanks for decades and not just the same stuff for half the price from an inland quarry that ends up being full of terrestrial phosphate and just gets the same pests/alage over time anyway? Why do I need to QT if my LFS said that they did it already?
If somebody posted that ditching their T5s and going all Radions got this kind of spurt for a FEW YEARS, and then outlined some typical kind of changes like this guy has, then I would take that as a data point and learn something from it as well. These kind of posts to not really exist except for initial reactions that fade over the years... so this is telling as well. We do hear of successes that have no photos or other folks to vouch. Instead, what we see is that everybody loves the LEDs for a while, then IF colonies ever appear and they start to die from the base up from shadowing and stuff suffers or many T5 tubes are added... and then people reassess. If they hobbyist/tank never gets colonies, then I typically do not give it much credit. I do not want to discount the few tanks/threads that are not like this, but they are truly few - these hobbyists have worked really hard and deserve a lot of credit.
I pay attention to all of these data points. Should TRULY better lights come along, I want to switch to them... and there is no way to know without paying attention to posts like these and finding some common denominators. If you have any kind of experience at all and add all of this up, you see that lighting is by-far the greatest factor and there are some clear winners in the long-term with colonies and mature tanks that vastly outnumber the others. Forget about the why and just look at the results.
You want some numbers for success? Let me know the size or your RS Reefer (sorry, I do not know which one is which), I will pick out a Giesemann Spectra for you, you can put it on and change nothing else and see results similar to what Schnitzel has had.
Dang! This was long. Sorry. It is Saturday night... I am truly a dork. Sorry all...
