siskiou Posted July 21, 2007 Share Posted July 21, 2007 Did anyone try to use them yet? I just tried it with my mjmod, but it's a complete failure. Six of them aren't strong enough to hold it to the glass, even turned off. Anyone have thinner glass/acrylic who wants a few more for a frag or something? Six (pairs) of them are glued to two acrylic strips, with felt protection on the magnets that might work as a pump holder for somebody with a smaller tank.

impur Posted July 21, 2007 Share Posted July 21, 2007 Mine are working for a frag tray nicely. They were a disappointment for the pump holders for me too. I've voiced my displeasure to them... I have an email back from a few companies. I'm going to order some magnets that will hold 10+ pounds. They will not be coated however.

spectra Posted July 21, 2007 Share Posted July 21, 2007 How many did you use for the frag rack? I tried with three and it did not work on the 29. Might try two more for five and see what happens not sure though. If it does not work will try some bigger ones. Quote Link to comment Share on other sites More sharing options...
siskiou Posted July 22, 2007 Author Share Posted July 22, 2007 Thanks for mentioning the frag rack. The six magnets are *just* holding it. I'll put the rest of them on, too, and use them that way! -Susanne Quote Link to comment Share on other sites More sharing options...
impur Posted July 22, 2007 Share Posted July 22, 2007 I just have 2 magnets on my first frag rack. Only 2 SPS frags and a large disc with zoas on it, but it should hold a few more frags no prob on my 75gal. Quote Link to comment Share on other sites More sharing options...
siskiou Posted July 22, 2007 Author Share Posted July 22, 2007 Well, I had to abandon the magnets for the frag rack, too. It started to sag alarmingly with 5-6 frags on it. Fortunately I had enough egg crate and acrylic scraps lying around to fashion a nice hanger. My previous one was too short and I didn't want to shock the frags by having them too high up in the tank.

So how many did you have on it? And how many frags were on it? Thanks! Quote Link to comment Share on other sites More sharing options...
siskiou Posted July 22, 2007 Author Share Posted July 22, 2007 I had six (pairs) on it. Keep in mind that my glass is about 1/2" thick. Would probably work great with a smaller tank. I had a bunch of frags (6 or 7) on it, but even empty it didn't feel all that secure. Quote Link to comment Share on other sites More sharing options...
spectra Posted July 22, 2007 Share Posted July 22, 2007 Well I just put four on a small rack and it seems to be holding on my sons 29. I have about 7 frags on it now so hopefully they will be there in the morning(laugh) Quote Link to comment Share on other sites More sharing options...
impur Posted July 23, 2007 Share Posted July 23, 2007 Here is an email i rec'd from a different company. He suggested some much larger magnets Hi Miles, Thank you for contacting us. You will need some pretty strong magnets for this purpose. It works well to use one of our large rubber-coated magnets for the outside of the glass as they will prevent sliding. You can see them all on this page: http://www.kjmagnetics.com/products.asp?cat=164. Either the BX0X06BR or DX08BR should work. For the inside resin-coated magnet, our BX0X08 block should provide plenty of holding force. If you have any other questions, please do not hesitate to ask. Best Regards, Kevin Stayer K&J Magnetics, Inc. www.kjmagnetics.com -------- Original Message -------- Subject: magnets From: Miles To: contactus@kjmagnetics.com Date: 7/18/2007 7:02 PM Hi there, I'm in need of some pretty strong magnets. I will be encasing them in resin and they will be used to hold pumps in my aquarium. So they will need to hold thru 1/2" glass as well as the resin, preferably holding up to 1 pound, possibly slightly more. Could you suggest a magnet that might suit my needs? Thanks for your time.

Twitterbait Posted July 24, 2007 Share Posted July 24, 2007 I am still in the test phase with the last batch to see what is the rate of degradation of the plastic coating and if there is any toxic or other result. I also want to see how they are affected by a few different forms of algae. when that is done i will work on using them for frags. I may decide to coat them entirely in a thin coat of silicone just to be safe. I am also looking at something to put on the outer plastic coating to reduct the propensity of them to slide under weight. Quote Link to comment Share on other sites More sharing options...
Twitterbait Posted July 24, 2007 Share Posted July 24, 2007 another thought: if you are not worried about how the magnet looks on the outside you can just dissamble a speake and use that on the outside to hold the plastic coated mags inside the tank.

impur Posted July 24, 2007 Share Posted July 24, 2007 I don't think the plastic coating is anything to worry about. Good idea on the speaker, i don't have any old ones though. I placed my order for 2 of the magnets that have 85lbs pulling force at K & J magnets. I'll report back. Quote Link to comment Share on other sites More sharing options...
dsoz Posted July 25, 2007 Share Posted July 25, 2007 Or try old hard drive magnets. If you have a HD crash on you, tear it apart. There are some really strong magnets in there. We use them to hold up papers on the 'fridge because no other magnet will hold up that much garbage. LOL You can try them on the outside of your tank. THey may not be pretty, but they are strong. dsoz Quote Link to comment Share on other sites More sharing options...
