Took the help of Bioflow M in Juwel rio240. I chose based on performance and a large sponge - mechanics are a priority. He coped with the task, with a pleasant bonus, he finally zeroed out nitrites. The fact that water pollution occurs when the sponge is removed is normal for this type of filter, I do not attribute it to the minuses. Different pros: Quiet Productive Biological filtration works big sponge The quality of materials. Different cons: Transparent container for ceramics - diatoms grow very well there. Very tight lid of the container and flimsy fastening of the nets in it. As you close the lid, the top mesh falls off. I'll glue it.
