monty703 Posted April 16, 2015 Report Share Posted April 16, 2015 http://www.truaqua.com/aquatop-internal-sponge-filter-caf-10.html Here is the perfect filter for Marina Breeder boxes. I purchased one for my show Betta's tank to filter the water for him as he's going to a show soon, then I realized it fits perfectly inside the marina box with the tubing coming out of the hole in the lid. I opened mine up and put in some zeolite media instead of the gravel it comes with. Takes a bit of effort to get it open but once you have you can add whatever media you want for your tank. You can also customize the sponge...use an aquaclear 110 sponge and cut it to size or any sponge media you wish to use. I like the 110 as it has nice big holes for bacteria to form in. You now have the best bio-filter for your baby shrimp breeder boxes. The babies will eat the biofilm off the sponge too. I kept mine in my Betta's tank for 2 weeks, so should have enough on it now for the babies. Price is soo cheap too.

Soothing Shrimp Posted April 17, 2015 Report Share Posted April 17, 2015 How did you get the top open? Quote Link to comment Share on other sites More sharing options...
chibikaie Posted April 17, 2015 Report Share Posted April 17, 2015 Just wiggle it a little - it will come apart if you work on it a bit. I took mine apart by accident and had to spoon the gravel back inside. Quote Link to comment Share on other sites More sharing options...

Elo500 Posted April 18, 2015 Report Share Posted April 18, 2015 I use these in my 3G critter keepers. Never thought of replacing the media. Soothing Shrimp 1 Quote Link to comment Share on other sites More sharing options...
monty703 Posted April 18, 2015 Author Report Share Posted April 18, 2015 its absolutely perfect for marina boxes and betta tanks/bowls. Quote Link to comment Share on other sites More sharing options...
Chiumanfu Posted April 18, 2015 Report Share Posted April 18, 2015 I have large hob marina breeder boxes on a couple tanks that I use for selective breeding and culling. I'm wondering why you need a separate filter. The stock air lift provides enough water flow to change over the water volume quickly. Other than having an additional place for biofilm to grow, is there any other reason to add these little filters to the box. Quote Link to comment Share on other sites More sharing options...
