GFO

from my understanding the brs method of doingit is pretty standard. off the top of my head i am trying to remember but its something like half the amount for x amount of weeks and then full amount after. start slow and build up so po4 doesnt take a fast and sudden dive down to nearly nothing.

i am going to tag along on this for other ideas on it as wel... i have two precision marine reactors...one i plan on using for carbon and the other for gfo...i have everything ready including the gfo i just havent had long enough period of time to get everything up and going for it.

 

Is it for the 34 gallon tank?

 

also the amout used will vary depending on tank size but one important thing to remember is to let the gfo slightly tumble around inside the reactor. to much pressure will cause the granules to break down into smaller sized granules and that will potentially end up free floating in your display. also you dont want the gfo packed into the reactor tight otherwise it will not do what it is supposed to. just a slight slow gentle tumble. i would think weekly water changes would be good but i think i read that gfo can or does strip your water of nutrients hence the slow initiation period of using gfo. after that period your livestock should be used to the nutrient change.

 

i think gfo is a fairly cost efficient extra insurance policy so to speak. so that lesser amount you used may be enough especially if you feed just what your fish will consume in a brief amount of time with very little hitting the sandbed or very littly spreading around in your water column is about one of the best things you can do. also a turkey baster or spot feeder and spraying off your rockwork before a water change will help also in my opinion and of course a strict water change regimen.
