Solder?

Recommended Posts

I wouldn't use it, alot of solders are lead based (although this is not so much anymore) but most of them have a resin based flux core which wouldn't be so good for fish I would imagine..

There is quite a lot of research about the detrimental effects of lead fishing weights on the health of aquatic species. Lead poisoning is cumulative (builds up over time) and some of the first effects are behavioural/mental/cognitive.

Would you be able to tell if your fish was starting to go a bit nutty?

I am sure the effects would be more likely to show up in long living species, especially those that are kept for a number of months/years in the same environment. Of course acidic water conditions would be much more likely to leach out the lead.

Would be very unfortunate to buy a seemingly healthy fish off someone who had been keeping lead in the tank...ticking time bomb.

Yeah most solders are lead free these days it is industry standard, but from someone who has done many many hours of soldering and I do it almost daily at work the flux is pretty nasty stuff I wouldn't want it in my tanks..

Rust is a complicated electrochemical process. In that system, there would be phases of soluble iron (Fe2+) that would be usable to plants (albeit unstable, but that is true for our fertilisers too).

It is also a myth that plants cannot absolutely use oxidized iron (Fe3+). Here is a research article that I looked up last month that clarifies the issue: http://www3.interscience.wiley.com/jour ... 1&SRETRY=0

I have no idea how much plants can use. I am sure there is more recent evidence that says as much, but if not, perhaps you can start a research study to find out? :D

For a bottom weight why not use unpainted iron? As it rusts away, it might release iron for the plants?? :o

Rust is the production of an iron oxide? Man chemistry gets boring.

Here we go! :roll: :lol:

Was for fighter fry but i'm going for the bottled method
