Removing Copper from Tap water - Necessary?

[Anonymous]

For the data you posted you can not even tell if the copper came from your caulerpa to the water of vice versa.

huh? How could the copper have come from the caulerpa? Please explain...

I give up how? :lol:

the point was the data collected does not rule out that possibility.

Just as observing a car at 60 mph and 1/2 tank of gas does not rule out the possibility of the motion of the car filling the gas tank.

Had you measured copper levels over time under controlled conditions accounting for all the sources of copper then you would have more.

But all you have is caulerpa, skimmate, and water at some copper level. It is not possible to say anything else. You simply don't know where the copper came from or where it's going. all you have is copper levels in those things at one point in time.

Just like a car at one point in time 60 mph 1/2 tank of gas. one single observation of conditions. it is not possible to say anything else.

I do feel confident macros can remove sufficient copper. After all hospital tanks must contain no macros or the copper medication is rendered ineffective. But doing the simulation would be interesting.

there are many things out there that can remove copper more efficiently than macros. I feel it is more important to prevent the copper from getting into your system. Then trying to get rid of it after its already in the system. That's why I use RODI water.

Even if macroalgae could remove copper all the way down to natural sea level values, they don't do it instantaneously. What did you say Bob, a few weeks, a month? Then you're topping off and adding more copper every day. Why? Why not just take it out to begin with?

Even if macroalgae can do what you claim they can do it's a bad practice.

Whatever. I see your intuitive abilities degrade when the presented facts do not support your theory.

It's quite obvious that the Caulerpa in my system did not remove a whole lot of copper as you claimed it does. It removed some but not a lot. I fail to see the significance of the source. Your theory that any algae can remove copper from any tap water regardless of its copper level is proven to be bogus. Sorry, you'll just have to deal with it no matter how hard you try to refute what is presented.

intuition is not science. The only facts presented are you caulerpa, water, and skimmate had given levels of copper atone particular point in time. No other facts have been presented and those facts are not being questioned

Again the only thing that is obvious are the levels of copper at a particular point in time. Nothing else is obvious. Anyting else from those facts is speculation.

I dont think macros remove copper? how do Macros use the copper than..it must be changed to something..that is a better question?? If you can explain that, then it may be more believable....

LOL. Blinded by the light...

>... I feel it is more important to prevent the copper from getting into your system. Then trying to get rid of it after its already in the system.....

Why would any reasonable person do that?!?! I would put more polices on the street instead of doing any crime prevention. BTW, it is illegal to lock your door at any time so that the police can get into your house faster...

Anyway, back to "serious" matter here....

>...So not having any better data it seems reasonable that a pound of macro for every 50g of water would bring down the copper level to unmeasureable levels in a month or so.

>...I presume it was dried weight as mass spectrometry (or however that is spelled) used in other reports. It was a summary of a report not the actual report so hard to tell.

If there is a pound of dried-weight algae in your 50 gal tank, I don't know you have the room to put any rock in.

You state that you are confident that the copper level in the water of a macro filled tank would be zero after a month and yet, it's there. I didn't speculate the copper level like you do, I had it tested.

Case closed.

Very good point Matt. Why add bad water, if what you are trying to achieve is pure water? The over all "method" is a silly one.

I have never stated copper would be 0 at the end of the month. Nor do I want copper at zero. After all it is a necessary element for livf and some amount must be present.

You measured it. True. You compared to to NSW values true. You have no idea how it got to those levels or any data presented those levels have any detrimental affects to your livestock. Meanwhile you had corals thriving in your system.

Your insistence that macros do no bioaccumlate significant amounts of copper is speculation. At least the data I am using measured the increase in copper in macros in controlled conditions over time. And my analysis I am working on will use that data. That requires more time and effort than taking a one time snapshot of conditions in an uncontrolled environment.

Meanwhile we both have thriving livestock in tanks with large amount of macros.

Yep. I have seen no evidence anywhere that macros can lower copper to safe levels.

The conclusion any reasonable person would come to has already been stated above. Eliminate adding as much copper as possible and if your tap water contains signicicant amounts of copper it needs to be filter prior to use. If you do not know the copper content of your tap water then you need to find out, or just use RO and not worry about your water being a source of copper.
