Maybe I am an idiot but I am going to give them a try. The 100 dollar price tag isn’t nice. I have 4 filter sock spots…which is even worse. 4 lines that come into the sump. Two of which have been diverted into a RedSea roller filter. In all Honesty I could get another Red Sea filter roller for the same price but the sock holder would be fairly worthless at that point . Currently it has been just using media cups for the last few years. Their website sucks and has jack for information. I guess I will be the test dummy. Lol…I will take donations for my reviews lol. Another big thing is that the filter rollers RedSea at least maintains itself and even removes the waste from the system. Yet, if I can get more filtration and it isn’t a dang nightmare. 50 percent goes into the RedSea roller and the other through the filter sock area.
