Fluidized Purigen Reactor

[acroholic]

I ran across this DIY fluidised reactor for Purigen. Really smart in its simple design. Purigen goes on the inflow side of a standard RO sediment prefilter container. Allows the Purigen to circulate, but not get into the tank. This concept will work on any BRS media reactor as well. I am using Purigen in the SeaChem "The Bag", stuffed into a TLF reactor in my 100 gallon reef, and it clogs and needs rinsing fairly often, with the Purigen still good. Also using it in a BRS media reactor in "The Bag", stuffed inside the media cartridge.

I'm gonna try this on my BRS Reactor. Any suggestions on how to convert a TLF 150 to this concept would be great. My main concern about the TLF reactor is the Purigen beads are so small and light , it would not take much flow to push them out and through the sponges TLF gives with the reactor and into the tank.

Welp, you definitely cannot use a nice size sponge to keep the Purigen in the reactor. I custom cut a 2" thick round sponge to go in the top of the TLF reactor, and the purigen went right through the pore structure. Got a bit of Purigen in my 100 gallon, but not too much. Back to the drawing board.

Problem is, I am space limited under the 100 gallon tank. Can't really fit in an RO container like a BRS type reactor. It has to be in-sump.

You can use a BRS in sump. If you pull off the mounting bracket you will gain a few inches.

Yea, I just don't have room in sump for one. I'm going to get one of these 1/2 size RO containers (5.5" tall) from a local supplier and see if I have room for an external mount somewhere under the stand.

I usuly mod mine I take the inner cartridge and remove everything in it including the paper stuff at the top use a screw driver to knock it out through the bottem it casus flow problems. Then I take dealt fine mesh the bag works or you can use the $1 ones you can git at petsmart push it through the top of the cartridge far Enid for the nipple to sit right then put the print back on the top to hold the bag in trim around the oring with a razor do the same with the screw on side I don't run the sponge in them they clog to easy. I use the same set up run phosban puragen carbon neozeo x2 in line just don't use bigger then 500 you pumps on them Thelma blow the seals out

what if you cut up a seachem bag and made a screen?

I appreciate the response, but I'm having a hard time following your post.

Sorry its herd to type on a droid my dangers are the size of 4 keys
Gona step by step it I found a stylus
Remove the media holder
Remove oring at the top
Remove the bottem there is usuly a cloth type stuff on covering the holes. Remove it it will limit water flow and shorten the life of your pump
The top has about the same stuff just real thick
Take. A screwdriver or broom Handel and knock the cores out pushing it inside and removing through the bottom

Take a sea chem bag cut it at the welds making 1 large sheet then cut in half making 2 squares
Take one square and push it in the top hole
Use the nipple on the cap to make sure the bag is pressed in so it will seal right then use the o ring to hold it in
On the bottom just center the other square and screw it togeather
I don't advise a pump over 500 gph I use a 300 gph pump to push 5 reactors
Puragen phosban carbon then 2 for neo zeo Ben running for 2 years with little problem just watch your buckles wen in unscrewing them

Well, I tried setting the Purigen filter up as per the video in a half size container and it was a big flop. The purigen just sat there and didn't move. I think the reason is not enough flow through the Purigen. I currently have my GFO reactor set up in line with this, so I can't turn up the flow through the Purigen too much or the GFO will pass through the TLF reactor I have it in.

But so not to make it a total loss, I will probably use the prefilter container/prefilter I tried for the Purigen reactor as a sediment prefilter for the GFO and Purigen in the TLF reactors I was using before. Hopefully, this will extend the time intervals in which I have to rinse off "the bag" due to clogging by crud.

I made a mainfold out of 1/2 PVC t' s and small valves to regulate flow I due take quite a bit to git it to tumble round 130 gph-175gph

Your instructions above, are they referring to modifying a BRS media container or modifying a sediment prefilter element? Thanks.

The problem is that the Purigen is so light it flows up and out with any appreciable current. If it weighed like GFO or sand it would work fine, but it can pass through any sponge I have seen, it is so small. That's why it needs to be blocked from exiting a reactor. It needs decent flow to fluidize, but needs a screen to block it from leaving because it it almost floats.

It's for converting the Di canaster like the one brs sells to a reactor with better flow
