what is the best way to remove phosphate?

[demifelix]

is that what you are using now Mystery? How does that work for you?

I've been using GFO since 2005 (or so).............generally speaking....phates stay at .028 or less.

 

[demifelix]

do you put GFO in your first chamber or second chamber? What pump/flowrate you use to feed water thru?

 

[acroholic]

you can use a BRS dual reactor, but personally, I use and prefer two singles. If you use a dual, then your flow rate thru the carbon is set by the GFO.

GFO needs a much slower flow rate than carbon, as it needs to be in a fluidised state. You can flow more water thru carbon if you do it separately.

Dave...do you use the granular or the pellet kind? Any suggestion?

 

[ralph atl]

pellet, imho. oops, sorry I'm not Dave.......

 

[demifelix]

I use the granular kind. Lots of folks swear by the Rox type, but I usually just buy the 5 gallon bucket of lignite from BRS. I don't see the Rox pellets as being worth the price difference, but that is JMO. The smaller particle size would probably filter a bit better, but clog up sooner, whereas the larger particle size would keep flow better, but filter a bit less efficiently (less exposed surface area). I think I use the larger grain size.
