Magnetic Coral Frag Rack Strongest N52 Magnets Holds Up to 41 Plugs (Medium Max)

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.

Product was made to perform well

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!

Was really liking this rack at first. Great magnets... almost too good. I'm new to reefing. So this could be my fault. But I think for something kinda pricey. They missed the mark on one thing.... I was cleaning my tank scraping algae off the glass. Needed to move the rack. Now here is the part that could be my fault but I feel quality error. I use mag floats and glass scrapers all the time. And unless you get a piece of gravel or sand stuck in between the scraper and glass it won't scratch the glass. Back to I guess my mistake. I needed to move the rack to clean the glass. I grabbed both magnets and slid the rack over. Sadly and I mean SADLY it put the deepest scratch "more like a long gouge" horizontal along my brand new tank. Now like I said. Could be my fault, new to reefing. But why make a product and call it quality and miss the mark on something so simple. Am I the first to move a rack like that? Super bummed... I would give it 1 star but maybe it's my fault for moving it the wrong way. Was gonna get more like this but not anymore.... gonna look into the reef rock rack "say the 3 times fast" and try and cover it and just let frags grow all over it... make the best out of a bum deal. Happy reef keeping. Ha

I bought the M and it's a good size for my 54g corner tank. It can fit 1" plugs but they are very tight. Some are hard to put in and especially then, take them out. The 3/4 plugs are much better. Then you can easily put plug into every hole.The magnets are very strong but still it's easy to move the platform around. I also like it's from transparent plastic and thus doesn't shade corals underneath if only partially filled.The only negative - Considering it's just a piece of bend plastic, it's easy too expensive.
