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

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

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.

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.

20 litres? That's awesome. Was the reactor you were using DIY or a purchasable model?

Thanks,

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.

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.
