Convinced of a link between GFO and Cyano (and not the good kind)

Foz Down alone can remove phosphates to the point(150ppbillion) where it is not reliably tested by most electronic meters, meaning the meter's margin of error is greater than the phosphate level. With Foz Down there is no need to use GFO and suffer with the other issues that GFO and reactors bring along.

Wai's should have 10 micron 4" diameter filter socks.

He didn't seem to, but none of the socks I saw there listed the micron size. He didn't think any were smaller than 100 micron.

They are the 10 micron socks at Wai's.
They're the same ones I got from Tim.
