great looking acro's and so many of them....

Maybe it's that you are increasing a nutrient in your tank when you start zeovit? Just a thought.

Not that old chestnut again!!! :lol: :lol: :lol:

oooooh cant feel any love on this one :lol:

makes more sense being a sudden drop in nutrients rather than the addition of one.

Think about this. Do a 50% water change. See how many corals die from that. You've effectively HALVED your nutrients, faster than zeovit will ever remove nutrients.

Now double, triple or even increase your iron input by 10 fold in a few weeks, see what effect adding that nutrients to your tank does to animals which are specialised in sequestering this element from water.

Which makes more sense?

Halving nutrients suddenly in an average non zeovit tank is unlikely to have any effect on a healthy acro.

Tripling or increasing iron ten fold? No idea, never tried it. You try it.

... so then why do you say the sudden drop in nutrients can result in coral death? It's something your uncontrollably adding which kills corals, not something your removing.

You have, you just don't want to believe it is possible.

Actually, when reading the theory by people who believe that zeovit does not lower nutrients, in fact it adds one, the argument I saw used to support this, was that if it was low nutrients that cause RTN, how come you don't see sps RTN when they are suddenly put into a low nutrient zeovit tank. That's what they said.

In fact, speaking as a guy who actually has a zeovit tank, this has been my experience, that the losses have occurred soon after putting the sps in the tank. Exactly what Habib, Bomber and LDuncan have said should NOT happen if low nutrients cause RTN, but rather it is iron.

So the very argument used to prove that zeovit does not lower nutrients, but adds one, is proved wrong by your and Habibs and Bombers own argument Layton. You have based it on a wrong premise, just assumed the wrong things about what happens in a Zeovit tank, and ran with it.

Just because a photo has been altered doesn't mean it's meant to be misleading. Many photos need to be altered to be less misleading given different color balances, cameras, etc. Take for example this picture that I've altered. Which is most misleading? The original on top or the altered on the bottom? Ignore how badly it was done, I suck at it. The bottom coloration is MUCH closer to the real fish.

[wasp]

Well you may be right Ira. The only problem I had was the inference that the picture had been altered for more devious reasons, when the person making the statement could provide no evidence at all that it was even altered. Just a blank statement.

Anyhow, this iron argument is really a blast from the past, an old chestnut, something that has already all been said.

I'll just say that I am happy with what I'm doing, and Layton you are happy with what you are doing, everybody is happy , so I'll leave it that way and not sit up all night arguing over it

Exactly. The bottom fish is altered poorly (no offence Ira ) and although the colour may be a better representation of the true colour, the photo looks over altered. Which is what i'm trying to say. Sometimes it's better to just under do it, and have the colour look more like it did out of the camera, than overdo the editing, and have it "look" highly altered, cause it can be distracting.

It's not really over altered, the overall color when I did that was just about right, my computer is right next to my marine tank, so I only had to turn my head a bit to compare to the real thing.

I use photoshop all the time to completely bullshit my shots!!!!
