I am sure your corals do fine in a 0 everything reef tank. But for how long?
Well, for almost all of my fish, and most of my corals, ten years now!
How long have all your tank inhabitants been living with you for? About two months, because that's how long ago you set up your very first tank. How on earth do you get off thinking that you have a leg to stand on when the extent of your success in this hobby spans a whole two months?
It really irks me that you think you know everything. You may believe that you have all the answers, but one thing you don't have is EXPERIENCE. Another thing you don't have is a PROVEN TRACK RECORD OF BEING ABLE TO KEEP A BEAUTIFUL TANK AND HEALTHY ANIMALS. You seem to have very little respect for those that have been able to successfully keep reef tanks for decades. You learn a lot when you spend a lot of time in this hobby. You learn what works, and what doesn't. Your inability to share in the knowledge of others is quite frankly, disappointing. The single best resource that we have in this hobby is EACH OTHER. And you are failing to take advantage of that resource.
It seems that it has never even occurred to you that you could possibly learn something from other people. And that's a real shame, because this hobby is so much more enjoyable when you are able to share it with other people. I feel sorry for you because you will never understand the joy and pride that comes from being able to look at creatures that you have successfully kept alive, bred, and have watched grow for years thrive in your tank. I feel sorry for you, because you are so close minded and stubborn, that you alienate everyone you talk to. I feel sorry for you, because even though you may have a good idea now and then, most of what you say is so preposterous that you have zero credibility. For god's sake, I feel as though I've had more intelligent conversations with my cats.
There is no substitute for experience, and with a tank that is only a couple months old that has been plagued with problems (you seem to start a new thread about a new problem your tank is having every week), you can hardly say that you have had success with ANYTHING in this hobby.
Why should anyone take your advice or believe you? Your tank has had nothing but problems with the way you have insisted on setting it up and running it. You have ignored most of the advice of everyone here, and the state of your tank shows it.
Yet you continue to stand on your high horse and lecture everyone else about how we don't know anything, and you know it all.
In short, your attitude stinks and many people here are sick and tired of it. Good day to you sir, and good luck with your horrible mess of a tank.
