Keeping used CA reactor media?

[cr500_af]

I have a used reactor that I bought which had been a CA reactor, and it's full of coarse media. I'm going to turn the reactor into a sulfur denitrator, and I'd like to keep the media for when I finish my CA reactor. I don't know its age or anything, but I'd like to put it away for later.

What's the best action? Freshwater rinse? Bleach/sterilize?

Bleach, rinse, dry - done

How long was the set sitting idle? If it was being used I don't see the purpose of bleaching if it was currently being used

You can use some the media in the Sulfur denitrator. Most Sulfur denitrators have a 1:2 or 1:3 ratio of sulfur media to calcium media in them. Sulfur goes on the bottom, then a sponge separator, then the calcium media on top. I have a couple Midwest Aquatics denitrators, and they are set up this way.

That's actually my plan, Dave, as my CA reactor has finer media. I have NO idea how long this reactor was idle, so I have to assume the worst out of caution.

I'd just rinse it and then you should be good to go.

You say that now that it is in bleach water....

No big deal; I still have to source a recirc pump for the SDN anyway before I can put it in use. Speaking of which, the DIY threads typically use a MaxiJet, which I'm not really excited about using externally. What are you using on yours, Dave?

I use a ball valved feed off my PVC manifold to feed the SDN on each of my systems. The manifolds are fed by either the return pump or a Dedicated external BlueLine. I use a dedicated BL40 on my 300/150 and the BL 40 return feeds the manifold on the 100 gallon.

I think I'll do it that way (manifold off the return as I have "pump to spare" on there now). Thanks, Dave. Off to buy some LSM on Tuesday I suppose.

If you need the LSM...I've got a gallon...brand new!
