Small Magnetic Acclimation Breeder Box Anemone Coral Strong N52 Magnets for 1/2" Glass (4.5" Cube)

This is pretty slick! I'm pleased with my purchase. I'll admit that when I unboxed it, I groaned. You have to peel a backing off both sides of each piece. With the first one, I pealed against the slots and the backing tore many times. By the time I got to the last piece I found I was getting pretty quick at it. It's not bad if you go slow and pull in the direction of the slots. You can use a sharp knife to start peeling at a corner. The instructions are pretty good. If you find that the pieces aren't meeting up correctly, you've got a piece backwards. You'll know it's right while all the pieces flit properly without gaps. The screws concerned me, but worked well. They go in easy and you just don't need to make them super tight. The magnets are STRONG. I'm using it on an acrylic aquarium. The back of the tank is 3/16" thick and that box isn't going anywhere. One thing to note is that the inserts that you use to attach the bottom are different sizes. The longer one goes in back.

I am pleasantly surprised by the quality and sturdiness of this product. Given some of the reviews, I was hesitant on trying this. I am glad I did try it! Pro's - Goes together nicely, is well protected in shipping, very sturdy when put together as shown in the directions, and strong magnets that do well with the 1/2" glass on my 90-gallon reef tank. It does require patience to slowly peel all the protective material off of all the main parts. It took me about 15 minutes to do so. Surprisingly I appreciate the protective material and think it is worth the effort for what you get. Cons - I don't have any. Tips - The direction of the tabs on the side panels does matter for ease of assembly and sturdiness when everything is secured. The small Philips screws require a #1 screwdriver or bit size and not the standard #2 size. This is important to ensure a solid and firm connection between the screwdriver and the screw. I found barely tightening the screw, more of slight pressure after it initially goes snug, worked well.

I have used acclimation boxes for years. Thought this one looked great as I loved the magnets. Would not interfere with my screen top. Assembly was easy but if you look at it funny it falls apart. Used for 5 days to house a lunare wrasse before I re housed it. The lid in that time frame began to warp from the UV in my reef lights. Was removed from the tank and cleaned with fresh water. The warping was so bad that the kid broke from the hinges. How good is a box you can’t close. No good. This was a definite waste of money. You can find a better quality box for much cheaper else where.

I love the box. It was simple to assemble, looks great, is functional, and I have been able to use them as a acclimation chamber for a fish, some anemones, and mushrooms. The bad thing about this is the magnet. The magnet will hold it, but it really needs two. Unless you put this at the bottom of the tank, the chamber wants to “turn”. If there is flow, or weight on one side it will lean that direction and “tilt” if it had two magnets on opposite sides it would be much better. It also has the magnet attached to the outside wall of the back wall. Making it sit off the wall about a 1/4 to 1/2 inch, but again, making it kinda unstable at times. It needs something like pegs at the bottom to help hold it off the wall some. Again, the magnet holds, but not really. I have the chamber in my 10 inch deep frag tank and have been just letting it sit in the bottom of the tank. The lid has kept everything in it I have needed. It’s hinged but no latch. Could also use a latch I think, especially if you have to put it at the bottom as it would make it harder for someone to escape. Would still recommend as it is functional, but if you have a deep tank, look for one that hangs off the rim or something. This one is just not quite there yet. Great idea, decent design, but could use some improvements. Still worth 4 stars in my opinion.

Awesome box, great quality, everything fits perfectly. Like the tabs to keep the box locked.

‼》PROS— ~ assembles easily ~ sturdy acrylic ~ decent amount of vent slots on all panels ~ magnet is decently strong; no slipping or sliding ~ detachable lid ~ no pieces to erode or rust; fully acrylic ~ extra set of screws just in case ~ true to stated dimensions ❌》CONS— ~ slightly flimsy; panels don't lock solidly together (but wont fall apart once fully assembled correctly.) ~ lid doesn't interlock/lock; simply lays atop the box ~ cannot hold sand or fine substrate; vent slots are too large ✅》OVERALL— 5/5 ⭐⭐⭐⭐⭐ pretty decently made box. wished the panels interlocked together a little more sturdily, but for the price, it's pretty nice. there are clear protectant layers you need to peel off before actually using it (for all the people complaining about it being "foggy" or not crystal clear. lol.) but it is actually completely transparent. it works pretty well for the purpose that i needed it for— temporarily housing anemones, so they wouldn't take walks all over my tank. and it is somewhat of a pain to clean if algae decides to collect and build onto it, but i just purchased my second box, so its definitely worth it if this is what you're looking for.

Great

When I put it together I had to use twist ties so it would stay together firmly. It did come with little screws however they are soft plastic and broke. Not all only two so I couldn’t put the top on. For the price you pay I would expect this to feel like it’s not going to fall apart when it was completely assembled. I would have returned it but that cost way to much to send it back. So after enforced with twist ties it’s much more secure.
