Then my cycle still wasn't done so I picked another DIY project to build while I waited. This one won't be used for quite a while but I wanted to build one to see if the idea I had would work.
So I took a regular 10" BRS carbon/GFO reactor and Made a few modifications to it. So first I had to add a couple of new ports to the top cap to feed the reactor and drip the water back into the sump. I also needed to turn the original in and out ports into a recirculating feed for the reactor. So here is what I came up with.
So CPVC just happens to fit into the intake side of a MJ1200 pump and the john guest/murlock connector that comes on the BRS reactor just happens to fit perfectly over the output spout of the pump. This makes a very clean and compact recirculation path for the reactor.
Here is everything assembled for the recirculation path and the two new ports added to the top cover.
When the CPVC pipe goes into the intake of the MJ1200 pump it nearly fit perfectly and that includes how it fits on the center hub that holds the impeller. This makes it so that the flow would be almost none. So I needed to fix that.
So I tapered the inside of the pipe to thin the walls of the pipe and open up the flow area around the center hub.
Here is the beveled piece next to a original piece. You can see how much I thinned the wall.
Here is how it looks once inserted into the pump volute. You can clearly see how much room there is for water to flow now.
Then I glued everything up and finished assembling the entire reactor. I actually built two of them as a friend wanted one as well. Here are the two tops almost completely assembled.
I drilled some holes in the mounting bracket for the top ports to allow the reactor to still be hung with the original bracket.
I'm trying not to give away what these reactors are but I wanted to show the completed assembly and that might give it away.
Then I needed to add the feed lines and control valve to the top ports.
Here they are completely assembled and ready to start working. Any guesses as to what they are now? Let's hear your guesses before I spill the beans!
