I'm currently using 200micron filter bags on my SW
tank and some generic polyfill on my FW
tank. The polyfill has done an amazing job for me (considering the cost) in the FW
sump and I'm considering switching to it on the SW
build. It would require some mods to the sump I have though.
The reason is cost, the dilemma is that I don't see anyone running polyfill on their SW
tanks. I'm still cutting filters from the sheet of polyfill I bought months ago at Wal-Mart for $6 but my $5 a piece filter socks are starting to fall apart after just over a month or two.
I don't think there would be any adverse effects on a SW
tank but I'm just wondering why it isn't done more. Is it just because DIY FW
tanks are usually done on such a small budget? Is it just a trend? I know some people don't even run mechanical filtration on the SW
so I'm just asking for some opinions before I order more filter socks.
