Magnetic holders for 6100/6200

[snorvich]

I have a variety of these on a tank which is 3/4 inch acrylic. Is there any stronger magnetic holder which will hold these more secure?

There is a new stronger magnet which is 6205.500, whoch comes on the 6205/6305 but I am unsure if there is anyway to attach it to the older style pumps

They can be attached to the older pump but it involves some DIY and the pump sticks out further. In the future we may have an attachment to directly mount the old pumps to the 6205.50 which works on up to 1" glass.
