Each rack is made from a reef-safe resin and has five pre-drilled holes for frags and come in two version – a magnetic one to stick on your glass and one that just sits on the bottom. The magnetic mount version uses magnets that will stick to tanks up to 1/2 in. thick. The mags are also plastic coated to provide a waterproof seal.
Now this isn’t something you’d probably want in any old tank and probably just a small set of people that want them, but if you’re a big fan of ESV and want to highlight it in a frag tank, in a retail store on during an event, this might be something you’d want. The white resin seems to pop nicely with actinic lighting and after a while you can even expect this to get nice and crusty with coralline algae.
The rack runs $25 without the magnets and $45 with the magnets.
