I’m having trouble with filtration I have a 40 breeder with a Fiji cube aio siliconed in it. I was using filter socks running through new ones every other day I’m currently using floss and a filter cup works the same but I’m able to just throw away the floss when used. I want to use a roller but can’t find one to fit the dimensions. I found a site that builds custom one called reefnroll has anyone ever used this site I want to know if it’s legit before I pay almost $300 for a roller. Does anyone have any better ideas. All comments are welcome thanks.
