OMG Rust warning

[reefman]

upon checking my DIY magnet holder, i found it rusted thru . so any1 that uses these magnets for PH holders, check it closely time to time. it may look fine in the water, but unless its taken out n inspect,
it may look like this

Did you notice a difference with your corals?

 

[reefman]

a few frags did RTN from the base but not sure if this is related. the leaching may be slow so it may be more critical in the long term effect.

What did you seal it with?

 

[DallasNYC]

What did you use to encase the magnets?

 

[reefman]

aquarium silicone

I dropped a 2in. by 2in. piece of reflector in my tank 1 month ago I can't get to it without moving a lot of rock.. In my 125 fowlr will this both the fish? If so how long down the line????

 

[reefman]

hard to say. rust is bad for corals fish,inverts,etc. but for piece of mind, get out anything that may rust no matter how much trouble.

 

[Bob 1000]

Thanks but I just hate moving rock...

Rust is ferric oxide, which is the same ingredient in phosban. So why is it harmful?

Here is a definition of ferric oxide -
http://en.wikipedia.org/wiki/Iron(III)_oxide
"Iron(III) oxide — also known as ferric oxide, Hematite, red iron oxide, synthetic maghemite, colcothar, or simply rust — is one of several oxide compounds of iron, and has paramagnetic properties. Its chemical formula is Fe2O3."


And here is a description of Phosban from the Two Little Fishes website -
http://www.twolittlefishies.com/tlf_prod_water.html?lang_id=1
"PhosBan?
Julian Sprung's Marine Aquarium Formula
This granular ferric oxide hydroxide adsorbs phosphates from saltwater and freshwater. Also adsorbs silicates and dissolved organics. Does not leach adsorbed substances. Long lasting and easy way to control phosphate levels permanently."

I don't think rust is all that bad to reef. Coral can be seen to grow on metal objects. I guess those are iron.

May be there are more for me to learn.

Really??? I am going to DIY my own phosphate absorbing material...:biglaugh: J/K

Phosban is more stable than the goop that's in there. If say its a good thing you found it as it looks more soluble than phosban or the kind we find on PHs. It would be harmful to fish,inverts, and i say irritate sensitive corals in that liquid form. Good thing it was stuck in place and not in the water column. Couldn't you have used a marine safe epoxy to seal the magnets in?

I think it may be more than rust leaching into the water.

Does anybody have personal experience with rust being detrememtal to their tank?
