Magnetic Coral Frag Rack Strongest N52 Magnets Holds up to 41 Plugs (Medium Slim)

These are by far my favorite frag racks. They look nice in the tank and the magnets are strong enough to go through the thick glass while being gentle enough not to scratch. I will definitely be purchasing again in the other available sizes.

These frag holders are an awesome addition to any reef tank, they are made of durable material and the super strong magnets hold the weight of many coral frags with ease. These are perfect for adding coral frags to a tank, without the commitment of gluing them. These racks are a good value and they are a great size, they look almost invisible from the side. I highly recommend this product for displaying and growing out your frags.Overall:+Strong Magnets+Ease of Use

Got this for my Waterbox 230 with 3/4" (19mm) glass. The rack looks good and seems stable considering the thickness of my glass and the high flow area I have it in. I've only put a couple small frags on it so far but it seems stable. Will probably buy another down the road. Beware that the title of the product is a bit misleading. The Medium Max only has 25-30 holes for plug placement. I think the product description mentions 27 holes but the title says "up to 41 plugs". 41 plugs is only for the largest size available based on the descriptions. I noticed this ahead of time but I could see someone being disappointed if they expect 41 plugs on the smaller sizes.Regardless, this seems like a quality product and I'm glad I bought it.

I Needed to order a frag rack to replace an older overly sized one I currently have. This rack was exactly what I needed. Rack came well packaged and they even leave the paper on the rack to avoid possible scratching to the acrylic during transport and manufacturing. Although someone decided to complain about that in their review?!?! With my finger nail I easily lifted the edge and pulled the paper backing off. Wasn’t rocket science.As for the magnets, they are strong and come sealed inside of the rack and the outside magnets are coated with a piece of felt attached to them. As we all know, sometimes water finds a way in so only time will tell on this. I mean maybe I should email the company and blast them about how they are sealed like someone else has done but what for? Many components we use in our tanks are made from some sort of metal and will eventually rust. That’s why we do maintenance and make sure to replace these components as needed.On to the placement in the tank and possible scratching. For people who use sand inside of their tanks keep this in mind when you decide to move the rack by grabbing the outside magnets and sliding them across the glass. Fish, power heads and inverts all kick up sand that can land on the rack and between the acrylic and the glass. By sliding the rack you will scratch your tank. However this has nothing to do with the product. It’s just the nature of using magnets to hold things inside of a fish tank.Overall, I think this is a well made product with a nice look to it. I’m not sure if they do but they should start making them in different colors (black). I’ll definitely keep this brand in mind if I need additional racks or similar products.

I've lost track of how many frag racks I've bought over the years. It has to be over half a dozen. They all broke or the magnets rusted. This one is very well constructed. One thing I particularly like is that, if you are careful not to scratch the plexiglass, there is no algae build-up and it's easy to clean with a wet paper towel or very soft bristle toothbrush with minimal scrubbing. The eggcrate frag racks I've had always attracted hair algae and because of the small hole size, it was impossible to remove it all so it just kept growing back. Also, critters like tiny reef limpets and micro starfish would always get stuck in the corners. Since I didn't want to kill them during cleaning, it took a while to pick them all off and doubled maintenance time. This rack also holds more frags in a smaller form factor compared to eggcrate. This is because of the way the round holes are positioned and the triangular holes are larger and give you more spacing options. Well done, Reefing Art!

The Max size work well on my Red Sea reefer 350. The magnets ate strong and hold well. Be careful moving them, sand / coraline algae and such can scratch the glass. The magnets on the smallest one will still hold on the reefer 350. Would definitely recommend

I just bought my second on after a few years. Not because the old one broke, just because I think it's a great product and needed more room. Functionality is great, looks good and easy to clean and slide racks around for feeding and repositioning.

Purchased med size, very well built. Magnet strength is very good. Extra felt pads for outer magnets is a plus! Looks great and great value for the money!
