GFO Dust

[reeferj]

First time using this junk. Wanted to take it nice and easy so not to shock the system. I added 5-6 tablespoons to a DIY dual media reactor I made this weekend. The gfo and carbon was well rinsed, till rinse water ran clear. I decided to test run the reactor in my sump offline from the rest of my system. After two hrs the water in my sump is orange. Now I assumed there would be a little cloudiness but this is nasty. Is this normal?

what are you using as a feed pump?

MJ1200, buts its adjusted down to half flow. GFO is still there. I wonder if it looks this cloudy because the water doesnt have a chance to disperse throughout the whole system?

GFO can be difficult to rinse. Some can crush pretty easily if there is to much water pressure. I know you want to run the water through very slow. When I use it I set the flow to where it will barely move the media. I would clean your sump out before you put it back online.

I thought I had low flow? But I just pulled out the reactor and its full of rusty lookin milk... the pellets are still there but it seems like some of it just melted?

Here is what works for me. Fill your reactor, DO NOT rinse the GFO in tap water or any kind of water. Turn your reactor on and let the outlet go into a bucket until it runs clear. Then place the outlet in your system...good to go and no GFO dust.

Go out to BRSs web site and watch the video on how to adjust it for the right flow. Here's a link:
