It matches from what I can see. From the low angle the photo is taken from, the reflection shows mostly the corals from the back part of the tank. Layton

:roll: Once AGAIN you are confused. You asked me about the RK TOTM. IE this tank: NOT that one you posted above. If you just skip to the correct thread ( http://www.fnzas.org.nz/fishroom/13-vt3 ... ?start=180 ), you'll see my response to the tank you posted above. It wasn't even discussed in this thread. Once again you totally disregard reality to post stuff made up by yourself just for the sake of arguing with me. It's getting beyond a joke. Layton

You can call it a faux pas, I know otherwise. ;-) Don't know. There may be. There may not be. Again, I wasn't commenting on whether there are such parasite in water collected by hobbyists. Just saying that holding water for three weeks doesn't necessarily large ammounts of bacteria or parasites. That's one large phylum your discounting there. Just because you've never heard of a case doesn't mean it can't and doesn't happen.

Now there's a challenge!

I know you searched for the first one (call it a tester ), but you stopped searching after that. You should be a little more persistent.

It would help if you wouldn't change the statement. I never said "with no host", i've said they may survive based on intermediate hosts such as copepods. You have been given an example of a parasite which can do this in this thread. Layton

Well it's wrong, that's the problem. Keep searching. My posts apply to saltwater. Your just confusing yourself trying to prove me wrong. Layton

This just confirms that you have no clue what i've been saying. As usual for some reason, you have in your mind i'm saying one thing, when in reality i'm saying something very different. You completely degrade threads on here when you do this. HERE is what i'm saying AGAIN:

You take absolutely everything I say totally out of context. It's pointless even trying to discuss things with you. It's just ludicrous. You interpretation skills need a LOT of work. Lucky you aren't involved in a science or engineering field. Layton

Not wasted or misinformed all. Keep looking. Layton

ahh, no I didn't.

I'm by no means a "fountain of knowledge on parasites". They are not "special" parasites at all. Some examples of fish parasites which have intermediate hosts are: Proteocephalus spp. Diphylobothrium spp. Many species of tape worm, and nematode worms. All capable of using copepods as intermediate hosts. As for cases in NZ, who knows. How many people get fish lab analysed for cause of death? Even if you did, you couldn't attribute the cause of death to using NSW, as you would have to have know that the fish was parasite free on introduction to the tank. That's something you can not do practically. But this is a digression, i'm not talking about NSW. Just the statement that water left for 3 weeks would kill a lot of parasites and bacteria, and be more benificial than adding it straight away. Nothing more. It's a point that seems to be missed on you. Also why is it that i'm always answering your questions, yet you won't even answer a single one of mine? And i'm sure you're capable of looking for this info yourself for once, how about doing that before you ask these questions? You may have intended it to imply that. I didn't. Layton

Yes, many parasites are very selective of their hosts. That's why Ich is an interesting one, as it hosts on a wide variety of species. Layton

:lol:

It's only twelve, and i'm already reaching for the whiskey... You really have no idea what i'm saying do you? Absolutely no clue whatsoever. Whether a parasite dies in under three weeks absolutely DOES depend on the type and it's life cycle. Layton

Jees, i'm not talking about NSW and whether or not it contains parasites around NZ water which are likely to infect our tanks! All i'm saying is that leaving water for three weeks is not going to necessarily make any difference to the number of parasites or bacteria in it. It certainly won't result in a massive decline in them, IF they are present. http://www.holar.is/~aquafarmer/node134.html Layton

I've never heard that one. Sounds like dubious to me. What reason did they give? Something to do with ion exchange I suppose? Layton

:roll: That's why I used quotes. "Good" bacteria can be "Bad" bacteria depending on the circumstances. I was just using the terminology which cracker was using, that's all. Parasites don't necessarily have to host on fish. They can have intermediate host (like copepods and other zoo-plankton). And have different life cycles which may be longer or shorter than that of Ich. To assume that they all have a thorrent stage lasting around 3 weeks is pretty sketchy. That's all. Layton

It's not splitting hairs. How do you think myths start? I don't like misinformation being spread. Keeping it 3 weeks, or dumping it in the tank straight away. I don't think it will make any significant difference. Keeping it certainly won't kill much bacteria. Layton

Sorry I don't realise that the dying plankton had a choice whether their decaying cells were used by "good" or "bad" bacteria. My mistake. ;-) It's every bacteria for themselves, "good" bacteria don't get first dibs at decaying cells. Maybe. But it's a bit of a generalisation, and i'm sure the really nasty ones, the ones you really don't want in your tank, can outlast that. I know that, i'm not taking a swipe at those that use NSW, i'm just questioning the rational behind storing it for 3 weeks to kill bacteria and parasites. That's all. But is it really? Layton

Depends on the life cycle and type of parasite. What makes you think there is nothing for the bacteria to feed on? Isn't one of the supposed benifits of using NSW (apart from the cost), that it is full of "life" which you don't get with ASW? Also a lot of bacteria don't die immediately when there is nothing to feed on. They can go into a dormant state (spore like state), and stay that way for many months, then spring to life based on environmental triggers. Really to kill bacteria and parasites effectively, you have to nuke them. They don't kill themselves very easily, or quickly. It's not obvious at all, and seems kind of a strange statement. Just because you leave the water sitting there, the bacteria dies off? I would actually think the opposite, you'd get an increase in bacteria, as the zoo-plankton in the water dies. Layton

How would that kill bacteria and parasites?

Can't say it really caught my eye. I don't think many of the photo's do it justice though. There are just so many tanks which look like that around. I like to see something different or unusually impressive. Layton
