Clogs quickly (using sanded as substrate)
Great price and very well made but both socks become clogged in one day. In their defense I have a sand bed and messy stingrays but BRS 200micron socks last 3-4days before clogging If you change the socks in your system daily these would be great!

Does not fit in Red Sea Reefer
I bought these because one reviewer mentioned Red Sea. For them to work in Red Sea Reafer tank they must fit flush and they do not. I tried a raser knife to trim them. Still did not fit. For other uses they should work fine.

Great socks for great price
Great socks works as advertised but itโs kind of a pain to put the sock inside out for cleaning. Other than that it does itโs job
