Tidal zones.....which SPS lie in have higher velocities, its more about pushing enough of that nutrient poor water across those tiny polyps for gas exchange and feeding, thats why they are stony and have small polyps to handle higher flow rates......but honestly why debate that if increased flow helps gas exchange and the overall health of the tank......I think I have an extra 820 Seio you can use if its a money thing.
But speaking of the money thing......this isn't a poor mans hobby by any means and as bad as a money pit as my custom cars were.
$500 Holley Double Pumper......$500 Euroreef Skimmer.
The whole energy miser thing is cool and an added challenge.....but like I said with not having the correct lights lights....just makes it that much harder to succeed in this hobby, as we can demonstrate by this thread alone, not to mention the thousands on RC, that this is not an "easy" or "casual" commitment......far be it that.
Lagonal type enviroments for LPS and anenome use less...more around the 40X mark I was suggesting, which I think your tank is emulating.
You have to realize though Edwin, a lot of the advice we share and why we share it is because we want to see everyone succeed and enjoy the hobby the most they can.......not be frustrated as all hell that all they can grow is algae and have nothing in the tank but 3 fish scratching on the rocks. As with most things in this hobby, not all is set in stone and there is "more than one way to skin a cat"........trick is finding out which way works for you........I think your on your way..........
I have learned and am still learning the hard way(anenome)....if I can share my experiences and opinions on why it worked for me I do so......unfortunatly, because nothing is not written in stone and we DONT know why hardly anything works the way it does in the ocean.....debates that can't be answered....like this one arise....but sometimes group consensus does work. I have noticed something lately.....most people have been giving adivce about additives that less is more, why is that?.......won't you agree that this chemical chemiclean could be considered that?.....but like I said, the stuff didn't work for me so I found another "natural" way to combat it. If you had your option, which would you choose?
Now if you would only wake up, smell the roses and buy some freakin Metal Halides.....you would be in a whole lot better shape.....just kidding.........gotcha!!!
