magnetic ceramics

[Scots_art]

ok i know you can buy magnetic ceramic rock already , but from what i have read it is as expensive here in the UK as it is in America.

I have ceramic rock left over , and i am just wandering how could i make these magnetic and reef safe.

the glass thickness is 8mm so i guess i need fairly strong magnets , the ceramic shelves would not be overly large or long so not to much weight.

i asked on the UK forum for help and i was told "" just buy the mag rock ""

But i feel £75 before delivery is over the top for such small mag shelf.
it is only 7cm long and with delivery it would be £83 which is roughly $130 lol.

surely there is a way to DIY mag rock.

I would just bore holes in the ceramics, and then use coated magnets. Use a 2 part epoxy to glue them into your structure.

Bump this. I would like to know too.

surely you cant just use any 2 part epoxy ? as i know most here in the UK have other chemicals added.

Get one that is safe for pottable water. You will be good.

that would just be aquarium silicon then.
as any other 2 part epoxy ive come across / used in the UK is not food safe. as anything classed food safe is deemed safe for use .

2 part epoxy is different from silicone.

 

[Scots_art]

i know they are different.
but all of the epoxies i have read available in the UK state they are waterproof but not to be used on water sources for human consumption.
and it was looking like i would have to use silicone for aquariums , or use Milliput.

Use a tube of super glue gel. That is safe for your tank. Just use a whole bunch of it.

yeah looks like that is about the only way. as i have been looking for epoxy again and all the ones ive found are not safe.
sent a few emails off to manufactures and 2 replied back so far . and at least they were honest and said we do not know if our products would be safe for aquatic use , how ever they can be used for leaks in pipes but only on out the outside and not in contact / submerged in water.

You can also use reef epoxy. The same stuff you would use to epoxy corals in place in your tank. Any LFS should carry that.

 

[Scots_art]

yeah we use Milliput over here to attach corals to rock , and i have loads of it :D

hmmm , i found one of the bits of ceramic rock i was wanting to use .
I supported it in the tank where i was wanting the shelf , stood back and thought na dont like it, went and sat on a chair and looked at the tank for a good while and decided i still did not like it.

So i will either forget about the shelf for now , or maybe i will have to look at buying one pre made.
