Review on Rusco Spin Down Water Filter by Peter Nobles

I bought a 2" 100 mesh SpinDown filter and a 1" Rusco 100 mesh polyester mesh sedimentation system. I also bought 250 mesh for each. They are installed from the same source on separate lines. The 1 inch model easily washes away all particles, even bits of algae. The 2" model clogs with algae particles after a few days. The flush valve does not clean the filter. You must remove it by hand and pressure wash it. BOTH filters are light protected (avoiding algae). The source of the algae pieces is water, which we control. I wish the 2" filter would create a better cleaning vortex. It's a problem to hand clean by unscrewing the housing. I really like the 1" but need to understand what's up with the 2". " is loose. If I change the grid, I think it's clogging. less often, but bits of seaweed will come through (not wanted) - Any help?
