Fluval Multi-Chamber Holding and Breeding Box, Large – Up To 3 Separate Housing Compartments

Works great. Working outside the tank but drawing water from inside saves space and helps to acclimate fish to your tank as the input of water can be adjusted with a flow adjusting valve on your air line.

The media could not be loaded. I love this box! It looks so much better than the mesh ones I had before. I like that it provides a separator for the mom and the fry. It has a leveling tool so you can make sure the box is sturdy and perpendicular to the tank, which I thought was pretty cool. I like that it also has a slot to cover the outlet to try to prevent fry from getting flushed back into the tank

The media could not be loaded. It came with no instructions, but it was pretty easy to figure out. The only thing I had trouble with trying to figure out is those two tabs that go underneath where it hooks onto the tank as seen in the photo I took in between the tank and the box underneath. Still don't fully understand the purpose of those two tabs. But it's whatever it may be. Right now it's on the back of a 29 gallon. It's a great box to breed fish in, put their eggs in, act as a holding tank, or even use as a specimen container if ur looking to sell fish or examine them! And if ur wondering what those two little rubber things are, they're the clips to hold the top down if u have any aquatic friends that like to jump or escape. I see a lot of people say they have gargling or sputtering issues with the set, but mine came with a cap the has another hole on the side and I just put it on there end of the intake tube on the inside and it's as silent as can be. At least for my ears. So if urs came with a clear cap that has a hole on the side of it, stick it in there and see what it does for urs. So for the lack of instructions for everything that come with it, i give it 4 out of 5. Otherwise if it had instructions to come with it, i give it 5 out of 5! Great box!!! Definitely recommend! Oh! The air pump I have that's running it is a 3W 2 outlet adjustable air pump for the stone and the intake. Works really good! Good flow! The 2 air flow control valves, the 2 check valves, and the stone with the suction cup all came with the air pump I ordered separately with this. The purple artificial plants I ordered separately as well. I figured it'd be good to put those in to help them feel safer and hopefully be able to see them better as they move around. Also provide more surface for bio film and beneficial bacteria to grow on. I would've put real plants in but hornwort tends to grow pretty fast and it's hard to see those little white babies swim around in them. Hah So I put a small dwarf water lettuce in there instead to see how it goes. But anyways, hopefully this review will help those who are thinking about getting one of these. In my personal opinion, don't hesitate to get this because it's so versatile and u can use it for so many things other than just breeding. It's a great thing to have in ur arsenal as a fish keeper/breeder and I think everybody should have them especially if they're just starting out in the hobby. Have a nice day!!

I’m using this as a grow-out box for my African cichlid fry until I move them to their own tank and so far it’s working great. The instructions are a tad confusing at first when putting together and it was a little frustrating that they didn’t include extra airline tubing for the other end of the valve, but besides this, not too difficult to assemble and place in the tank, took me maybe 10 mins max. I like the dividers that come with it, I had planned on using them and separating the fry by mothers but by the time it had arrived the babies had already been mixed together for a while and it would have been really difficult picking them out and manually separating all of them. A lot of people have mentioned that the tube and cap sputter and gurgle which is true, but depending on the flow you set and whether or not you put the lid on the box it may be more or less quiet. Personally it doesn’t really bother me and I barely hear it unless I’m really listening for it but if it does concern you there are plenty of reviews that offer solutions for this. I initially worried about the tiny babies swimming up to the section where the water flows back into the tank and potentially falling through but the 5 bar attachment prevents that for anyone with extremely small fish. I also really liked the leveling attachments and how many options there are for positioning and angling and the box itself seems pretty sturdy. The only advice I can give is just to make sure you’re cleaning out the bottom frequently to avoid ammonia buildup and doing a good amount of water changes.
