Review on Uxcell Aquarium Cylinder Shaped Intake by Lisa Perez

Beautiful design, good workmanship. I've used sponges on fences before, but they clog up with mulch so quickly (2-3 days) that I had to constantly clean them. This is a sieve, so there is no real environment for the bacterial culture to grow. Just rinse well every 2 weeks and you're done. I use it on my internal nitrate reactor and also on the inlet to my external filter. Only* complaint is that I don't have a larger size. Uxcell, come on, please. They need to make sizes up to 1.5 inches for the aquarium trade.
