Hi!

Can someone give an opinion about my icp test results. What do i need to fix

Are you having problems with creatures in the tank?

Tin seems the most concerning (IMO) on the high side, but it might not be high enough to cause problems.

What do you mean with creatures?

This is how the tank looks like

 

[Dr0pl3r]

we dose heavy metals to the tank so that might be the cause?

I mean are you looking for an explanation of why something organism is not thriving or dying, or just checking up on the water chemistry for "fun"?

Tin wouldn't be in most commercial additives at a concentration high enough to boost it like that. There's no reason to add any.

We are basicly checking for fun. We have been manually dosing elements to the tank over time so i wanted to see if some of the elements were out of range. But we have had some lps corals die the last month but that could be a copperbands fault. He is now removed. Jod and Barium seems a little high. So i think we will pause that until its in range again. Should we do anything against copper and tin?

 

[Dr0pl3r]

We dose these addatives couple times a week: fluorine, iodium, iron, kalium, strontium and micro e (contains: concentrated heavy metals manganese, vanadium, zinc, nickel, iron, chromium, cobalt & copper.)

 

[Randy Holmes-Farley]

I don't think barium is a concern at that level, and wouldn't intentionally be in an additive either.

The copper isn't high enough to be a problem (I had it twice that high one time I checked my aquarium years ago), IMO, but it can be lowered with something like Cuprisorb.

Tin might be from metal parts in the water, or maybe hard PVC. Cuprisorb sometimes works for it too.

Jod must be a typo???

 

[Randy Holmes-Farley]

The high iodine is no concern.

 

[Dr0pl3r]

The high iodine is no concern.

Jod is iodine on Norwegian. Sorry didnt realise they where the same

I think tin shouldn´t be in a commercial trace element additive since it is no essential trace element for organisms. There are no positive biochemical functions of tin known. So tin in a trace element additive makes no sense to me. The essential transition metals listed above are quite complete only lacking molybdenum and selenium (no transition metal) as far as I see.

where do you think tin came from? What source should i look after

I know of one case in The Netherlands where the little brittle stars in a public aquarium where dying first and other critters followed. It turned out that tin was the problem. The aquarium got seawater from a water ballast tank of a ship. It turned out that there have been soldering works in the tank of the ship.

To be honest I find it difficult to speculate about the origin of the tin since tin is not a metal of widespread use contrasting to for example zinc or copper. Soldering is something that comes to mind at once but what else?
