How do you use it?What Is yalls opinion on these? Do they work for yall?because the sure do work for me .
I find scrubbers, the plastic tangled ones very good. I don't really care about mechanical filtration, but for biological filtration, they do the job. The colours are kind of ugly, but no one sees them. I jam them into a HOB, and use a coarse sponge on top. Plus I use a lot of Japanese filter matting - recycled plastic fibre mats. Ugly blue things sold for ponds. They are great, and are gradually becoming my go to.
