GFO (Rowaphos) Coming Out Of Reactor

[BigEZ77]

Hi All,

I'm running a midsize minimax AIO reactor with Rowaphos in it. The problem I'm having is that the sponges that come with the reactor don't hold the product in place (even at lowest flow rate) and let some particles escape thru the sponges. I tried using filter floss to hold down the top sponge but the particles still come up into the filter floss. Would it be ok to use the filter bag that comes with the product in the reactor or is that defeating the purpose of using a reactor to begin with?

Thanks,

I had that issue too and ended up with brown particles everywhere, killing most of my corals. I stopped using it asap. I'll be following this post though to see if there's a solution...

IME, if you are having GFO (or Rowaphos - same basic difference) escape out the top it is because the flow is too high.

i had the same issue as well. i had to use the bag that comes with it. using it in the reactor is definitely better but my tank was turning red from the rowa particles so i had no option but to use the bag. all the corals got through fine though.

Can't get the flow any lower unfortunately. I think the sponges in this specific reactor aren't the best.

Thanks pyithar. Think I'll have to go that route. Do you know if it reduces the effectiveness at all?

does your skimmer have rust colored skimmate? most of the finer particles should get filtered out on the skimmer.

i think it does reduce the effectiveness. since the media is not tumbling anymore there'll be less contact with water and it will also clump after awhile in the bag. i put the bag in a diy reactor and let the water pass through it. i didn't notice any big difference before and after the use of bag though. but my skimmer and algae scrubbers can handle the nutrients pretty well so i don't really need to rely on it.

Do you have a ball valve like the one below on your pump?

Sorry, the title is wrong. They're not actually coming out of the reactor, they're coming above the top sponge into the area where I have filter floss to hold the top sponge down.

In respect to any plumbing...this is an AIO reactor (Minimax) so unable to do so.

i use a minimax and it certainly is adjustable.
watch this:

at the very beginning of the video he is turning the knob on the top which rotates the inner sleeve of the reactor opening/closing the drain vents.
i strongly suggest you do it slowly or you'll end up with a bunch more gfo in your sump or tank.

Thanks Johnny. I have done it very slowly and understand the concept of the reactor (biopellets are not as light or as fine as rowaphos). Unfortunately, even at the lowest setting it tumbles the rowaphos so I have put in filter floss to hold the top sponge on top of the rowaphos so it no longer tumbles. At this point, particles still get thru the top sponge into the filter floss. However, I doubt any particles are getting past the filter floss.

i use gfo in mine which if opened even close to halfway is far more tumbling than they need and results in the media spilling into the sump... trust me i know from experience lol.
maybe rotate the bottom and top sponges if they won't stay put would be the only other solution i can offer.
hope it works out man!

The gfo should tumble to be most affective. If your pump is too strong and a ball valve won't work for you, you may need to get a smaller pump. Also, just run the return from the reactor to a felt filter sock...it will keep the sediment out of the sump and tank. That's what I do and my sump and tank stay sediment free.

Now thinking of going with Phosguard in this reactor. Thoughts?
