metal contamination in tank

[KevinK]

I was gust wondering if someone knows the effect ore experienced galvanised steel in a reef tank.

reason for asking is because I found a big galvanised bolt in my sump.

the bolt is not so galvanised any more (in fact it is one bunch of rust) but it once was a bolt.

it most have bin added by my little son sneaking in the filter room, and as the bold rolled underneath my skimmer, I had no knowledge of it beighn in my tank system.

as I have bin battling / recovering from some tank problems (algae and corals turning brown )

the bolt must have bin in the tank for at least 1 year, as also some corals where turning brown (thy are recovering)


as I improved my entire maintenance, I don't know if the improvements are duo to the changes I made ore duo to removing the bolt



did anyone had a metal contamination, and what did it do ?
