Rowaphos / GFO

[shaunchan]

Question for people running GFO (either via media bag or reactor):

Once you see that Phosphate levels are in the desirable range, what do you do next?
Do you stop running GFO completely (which will make the levels rise in a week), or leave it running (which will probably drive the levels even lower)?

My query is how do you maintain phosphate levels?

You can have a valve on the reactor. Slow down the flow to maintain the right levels

Find your balance! If you have went under the desired levels.. you can just try feeding more and observe. 

Increasing po4 levels are not as difficult as lowering the po4 levels btw.
