cDrazy Posted September 26, 2015 Report Share Posted September 26, 2015 Hey peeps, have had a few Ls of purigen in my sump for sometime and it seems to not be doing what i needs to in a sump setup prob better with water forced through it like a canister filter etc so im going to make a reactor, anyone done one or modified a phosban reactor or the like for purigen? Needs super fine foam or a slower feed lph to work id say or??? Ideas. my tanks super clean but only the outside of the purigen is getting dark and soaking up the crap so i have to massage the media bag to get newer media to the outside if that make sence, so purigen needs to be force fed or fluid bed in my opinon Link to comment Share on other sites More sharing options...
Donny@ageofaquariums Posted September 26, 2015 Report Share Posted September 26, 2015 The German had one going a while back. Something I have done before. Can be tricky keeping flow constant to prevent any leaking back into tank. Recently tried knotting some into a filter sock with less than spectacular results.

The Tech Den Posted September 26, 2015 Report Share Posted September 26, 2015 With out using a reactor a good way of running it in the sump is to hang it on a baffle where the water goes over. Have a bit of play with it and you will find that the water will flow through it really well. Link to comment Share on other sites More sharing options...
Lofties Posted September 26, 2015 Report Share Posted September 26, 2015 Best way I've found is to run it in a fluid bed filter. I buy the Otto ones from the Tech Den and half fill them with Purigen-works a treat. Link to comment Share on other sites More sharing options...
Donny@ageofaquariums Posted September 26, 2015 Report Share Posted September 26, 2015 The otto ones do work well for it. Link to comment Share on other sites More sharing options...
cDrazy Posted September 27, 2015 Author Report Share Posted September 27, 2015 Sweet will order a otto and give it a try, prob have a bit much in my filter bag so its a little tight maybe half my amount in each bag to let it suspend a little more in the water, but reactors are cool so ill do that Cheers Link to comment Share on other sites More sharing options...
matt_a Posted October 8, 2015 Report Share Posted October 8, 2015 Media reactors are the bomb, by far the best way to make use of purigen/macropore. I was running (and will again soon) about 20 litres of macropore in a reactor and was really surprised by how well it worked, it was removing colour from the water that I didn't even know was there previously.

matt_a Posted October 8, 2015 Report Share Posted October 8, 2015 You basically want just enough flow to fluidise the media. In a tiny reactor such as an Otto I would be guessing your be looking at a 100L/h or maybe even less. Link to comment Share on other sites More sharing options...

That's awesome. Was the reactor you were using DIY or a purchasable model? Thanks, Bob Link to comment Share on other sites More sharing options...

ozmo Posted October 8, 2015 Report Share Posted October 8, 2015 How much flow is recommended to run through an Otto unit if Purigen/Macropore is used? I use the Tunze Nano pump with several OTTO FBF. Once the media becomes totally seeded (after a month or two) you can almost run this little pump at full speed. The only problem with it I find is the suction cups are too small and give way art the time. There are ways around it though. http://www.thetechden.com.au/Tunze_Nano_Pump_0800_040_p/0800.040.htm Link to comment Share on other sites More sharing options...

What size fittings on the Otto unit? I'm guessing 12mm hose? Link to comment Share on other sites More sharing options...
ozmo Posted October 10, 2015 Report Share Posted October 10, 2015 Thanks Boys.What size fittings on the Otto unit? I'm guessing 12mm hose? 12mm will fit but the original OTTO hose is a little thicker and broader when comparing to say Eheim hose. Link to comment Share on other sites More sharing options...
