Tungsten at 2.88 µg/l

griff500 · Jun 19, 2018

Is that anything to be concerned about? If it is, or perhaps even if not, is there a way to remove it? I don't want to use GFO as I currently have undetectable PO4 (although an ATI test came back with 0.05).

I'm guessing it could come from one of the pumps or a magnet in the ATO sensors. I also have a Vertex ground probe but that should be made of titanium and I'm guessing shouldn't be the source of any tungsten?

I'm not sure what level of tungsten is an issue, since we do not have much data on it and metals like tungsten can be in a variety of different forms with different tox profiles.

Does the tank seem OK?

Here's a current related thread:

I'd looked at that thread. The tank seems ok. Some corals are a bit dull to browned out but others not and all are growing at a decent and noticeable rate. All are frags, so I'm not particularly concerned about the colours yet as the parameters are just now becoming settled in the right range. Some cyano but it's diminishing with a lack of tinkering and some stability.

I was curious as to whether it was anything to be concerned about as I've previously fixed 'issues' that could have been left alone and caused more harm than good.

& his tank was still styling

then back down

(W) is done a lot form the 320 reading I had last time. So I feel that the source of contaminate was in fact the Ecotech wet side assembly for my MD40. I'm not going to do anything about that as it seems to be going down on it's own
