Which casting resin is AQUARIUM SAFE?

[ReefObsessor805]

I am going to make a magnet mold for my MJmod, and I am wondering which casting resin is AQUARIUM/REEF SAFE?

Would all casting resins be reef safe once they have cured?
What do I have to worry about?
Or do I have nothing to worry about? lol.

I may use this resin...(in white)

But I'd like to find the 1:1 mixing resin like this...

Can someone point me in the right direction here?
Thank you.

Also, I am ordering the swivel mounting bracket that goes onto the Taams (Rio Seios) and modding it to my MJmod so it can be pointed in different directions.

Is no one actually willing to help me out here?
BUMP.

I have been looking for the same thing! Lowes has an elmers resit that looks like the one you posted from michaels but Im too scared to try it not knowing

I used the michael's resin and haven't had any problems....but they have only been in the water for 3 weeks

 

[ReefObsessor805]

Sweet. Did you use the clear curing?
Or did you find some that cures in a white color?

And was it called Castin' Resin...or something of the sort?
Thanks

Most will be rather inert when cured. UV resistance could be an issue though. They may yellow or harden enough to crack over time.

I wanted to do this project also, but was unable to find any casting resin locally.

Any ideas would be appreciated!

Polytek.com Get their Poly15 series casting polyurethan plastics. Very durable, wood like properties. machinable, stable, may yellow over time, but will take any casting color additives to make it blend into your aquarium. I have been using these materials for years, I have a bracket I made over 2 years ago still in my tank, and its absolutely fine.

I actually found some on my lunch break today. It was $12 for a big bottle and $5 for the hardening stuff. They also had the neo magnets, 4 for $3, so I bought 16 of em for $12. I was thinking about using 4 per side to make sure it sticks really well.

All I need now is the nylon screws and the tap set. Should be able to get these at a hardware store?

What store did you find the Neo magnets at for so cheap!?
What size are they?

 

[bobt2]

any epoxy resin should be fine. you can get tubes of coloring agent at a marine supply.

It was an arts and crafts store, Michaels. They are round and about the size of a penny. Four to a package and two packages stick together really well, hard to pull apart.

They had the coloring agent for the resin there as well. I figured clear would be fine, it'll be covered in coraline in a couple weeks anyway.

Anyone with first hand experience on what size magnets are needed for thicker glass?

here is the Ebay store I use for my magnets. http://cgi.ebay.com/Neodymium-Disc-...QihZ006QQcategoryZ413QQtcZphotoQQcmdZViewItem
I found them useful to decide which magnets to buy..

 

[mmoore0803]

I used the clear resin

 

[ReefObsessor805]

I found these guys to be the cheapest...
http://www.forcefieldmagnets.com/catalog/index.php?osCsid=c912d7da38df0433a5b182b33f14f221

I ordered two 2" x 1" x 1/2" Neo magnets for around $17.
I am going to run down to Michaels today for the resin...

And I received a fax order form from Taam (Rio Seio) for the swiveling mounting bracket kit...$9.99..
which should be here soon b/c they are right over the hill from me...

In all, it's about the same price as ordering a Suregrip magnet holder. But with this project, I get to make it myself...which is fun and knowledgeable, and I get to use a mounting bracket that will enable me to point the powerhead in various directions...

I am going to do the same thing on the other side of my tank...
and have the two powerheads alternate every two hours on my RKII. Sweetness...

I have been doing this for about a year now and I can share the information below based on my experience.

1. Magnets: You should go with N52 magnets. I use round ones that are 20mmX10mm.
2. Clear Resin: Most is safe once you let it cure for a few days under water. I use the Home Depot one. It runs about $30.00 and you can make more magnets than you may need.

My experience:

• You should get the rubber ice trays from Ikea or some other store. This makes it easier to make and remove from the mold
• Pour a small amount on the molds first and let it dry without messing with it for 24 hours.
• The next day, glue the magnet to the resit already in the tray and pour the rest of the resin to cover the magnet..
• Make sure the magnet has at least 2mm of resin around it to ensure it is water tight.

These are the cheapest magnets I found and they are super strong.
