Review on Bluecell 12Pcs Pre Filter Sponge Aquarium by Ian Welch

I bought these for a filter in my shrimp tank when I noticed my cherry shrimp females were starting to produce berries. Glad you did! Your babies are microscopic to begin with and the filter would suck them in right away! I didn't notice a significant drop in suction initially, but I've been using it for a few months now and my filter doesn't seem to be working at normal capacity, although I've taken everything apart and checked for clogs, but I'm not sure yet they are guilty or not. The shape seems generic and fairly flexible and will likely fit any type of input filter. My shrimp love to climb on it too. I've taken them out and washed them regularly so they don't get dirty, but eventually they went too far and stopped cleaning, so I have to throw them out and buy new ones. Not a big deal as they are so cheap and come in huge packs. I don't think I'll run out of them anytime soon, but I'll definitely be buying them again when the time comes.
