I used this for a 5 gallon all grain batch. I use a hops bag with hops pellets, so all I want filtered out is a stray grain particle or maybe some hops sludge that leaked out.
The problem is the 400 micron strainer is too fine, and it silted up and got blocked. I had to stop filling it, and repeatedly scrape away some gunk with the and of the Silicone hose. I removed the filter, squirted some Star San on it to clean it (unblock it) and again it silted up. (maybe a pain brush would work to unclog it?)
If I had more sludge it would have been a real pain.
I don't plan on using this again. I will only use it if I am careless with the hops bag and spill some sludge in.
Thus it may make sense to get the 600 micron strainer insteadhttp://www.usplastic.com/catalog/item.aspx?itemid=37442
