DIY phosban Reactor

[Im Lon 2]

Over the weekends I went to Mikes (stupidsreef) and he showed me an old RO unit that he no longer used, and was wanting to know if we could make anything out of it. I have been looking at Phosban reactors to run carbon in my tank for a couple of weeks now. After taking it apart we were able to find a way to make this work perfect.

Since he already had the parts it only cost us a total of a $1.62 for a couple of bar fittings to hook the line to.

I was rushing to make this and didn't take any detail pictures, but I plan on building Mikes this weekend so I will try and snap a few picture of how I put the inside together.

I have a pipe that runs down the center of the RO canister so the water is forced to go to the bottom of the canister and then back up the through the pipe to the tube so there is full contact with the carbon.

In the picture you can see the carbon being blown around at the top.

My next step this summer is to get a new RO/DI unit with dual DI's. I then plan on taking My DI chamber off and adding it to the New RO/DI unit giving it 3 cambers of DI.

With the old RO unit I want to run in a series all three canister. 1st one being carbon the 2nd being Phosban, and the 3rd one being carbon. Does anyone see this being an issue?

So this would be circulating water thoughout the sump, correct? What do you use to get the water to the unit?

Right now I'm using a MaxiJet because I had one sitting around.

Yes it is sitting in my sump.

Well since so many people seemed so interested :lol: I thought I would post a few pics with out the Media, giving a better Idea.

That's pretty cool!!!

I think for the Phosban one, you might want some sort of a ball valve to control flow but I don't know what that will do to the overall flow in your series. I.e. will pressure build up? (I'm HORRIBLE at this DIY stuff).

I would run a 2nd carbon and then switch out one every 2 weeks. I ran my phosban reactors in series with the phosban followed by carbon and I kept a much higher flow since the carbon was there to catch anything that may have ground up small. I can't say I had any loss of media so I don't think the higher flow ground it up though. Also, the less room there is with phosban it seems you can pump water faster since there isn't as much room to rattle around. That's why cannister filters work better than the reactors is that you can sandwich the media and force the flow w/o it rattling around.

Can you run Carbon and Phosban in the same canister? I do like the idea of having Carbon after the phosban.

Is a full canister of Phosban to much?

You can run them togather but the problem with that is the carbon is done long before the phosban. Unless you are having a large phosphate problem. Once you reach low levels of phosphate you could just put a small amount in with carbon and then change more often.

I meant I have 2 phosban reactors with one output going to the input of the second, thus one pump. I have changed that recently though because I decided to put a mj1200 on the carbon after I started running ozone just for safety.

You can put as much phosban as you want provided it will let water through. If you had a huge problem with phosphates and just started phosban I'd start with a smaller amount as to not shock anything. But if you've been running it, then no problem.

No I don't have a big problem with Phosphates, just wanted to be able have it there If I need it.

I have seen the black Diamond also makes a black and white mix for ammonia. Again don't have a problem just like to have the options and know what each one does, just in case it is ever needed.
