Oceans Wonders MAG Rock 6.0 Magnetic Coral Frag Rack Plug Holder with 6 Plugs

I figured some of the low-stars on this product was because, perhaps, the customer received a lemming. My experience was exactly the opposite. First, the magnet is more than strong enough to go through my 3/4" glass and holds onto the tray WELL. It looks great too, but you can tell that by looking at the picture. Eventually, it will be covered in coralline algae anyways, so the initial purple is not permanent, unless for some crazy reason you clean it regularly. I am not certain if one cleans it regularly that it will not start showing up chips in it, revealing very white plaster underneath. I think you'll be very happy with this purchase. If however, your glass is thicker than 3/4", I'm not sure how well the magnet will hold.

I almost didn't buy this because of the reviews. But maybe they have updated the product since the other negative reviews. The magnetic is very strong and it does come with 6 purple plugs but the plugs I already had with frags on them fit perfectly. so maybe they have made the holes bigger. I think it was a great value for the money. All the other frag shelves that I looked at were way more expensive. I suggest you give it a try if you don't like it you can always send it back. I will be purchasing another one.

Gave 4 stars bc it arrived broken due to inadequate wrapping (obviously you can’t ship ceramic in paper alone) but it was an easy repair so I kept it and glued it back together. Looks much better in the tank than a regular drag rack. Magnet is strong.

I originally bought this trying to get mushrooms to grow up the back of my tank wall. That hasn’t happened yet but we love the look! Friends of ours loved it too and bought some for their tank. It frees up space seeing as we only have a 75g and are not looking to upsize. We will be adding another one as we need rock more space.

As you open the box it’s packaged well but gosh this thing is nothing like rock, had a coworker open the box and she said did you order play-doh with scratches on it. For $30 you’d expect more of a real looking piece of rock-work. Yes it’ll be covered in coralline algae and yes the magnet might be a little pricey(look them up individually) but still this is a disappointment. Really was looking forward to adding it to my reef tank but 2nd guessing it now.

I really like the rack a lot. Once coralline algae grow on it I'll like it better. I do have two problems with it, which made me almost list it as a 4 star. Right now, the rack is blue in color and does not look like the picture. Most coralline algae is purple or pink. The rack I received is blue with hints of pink. It will take some time to match. Do don't be alarmed if yours come blue. Also if I try to move the rack up or down from the outside, it starts twisting. I have to use my algae magnet scrapper to move it up without reaching in the water. That's not all that big of a problem, but two magnets one on each end would prevent that from being a issue.

Holds well on my glass

Shipping was fast and as describe. Magnet is powerful. The only thing that i didnt like with it for it to have 5 stars is that the holes are too small only their plugs will fit. So for me i have to unmount my coral from their plugs. If they made the holes a little bigger so it will be somewhat universal for a purpose of being a frag rack.
