T1, you don't know anything about me. Assumptions that I'm arogant about breeding rays is a joke I find funny. Ask anyone who knows me. I'm very humble. I openly acknowledge I'm a piss poor ray breeder. I've probably lost more then have made it and still have NO clue why I have so much trouble. Sound like a big headed raykeeper? Why do you think I'm so passionate about filtration and stuff like UVs? Issues between us stem from the fact that you are quick to call things like expensive UVs and K1 rubbish cause you don't need them for your big tank and light stock. Not many people here have nor want light stock. They want as many rays as they can possibly fit in the tank while keeping them happy and healthy. One says more, better, improve. The other says good enough, rubbish. Simple as that. Agree to disagree.
As far as the original topic...... Here's a good read. Changed my outlook on beads a bit.

As far as reactors, it's not simple as media and bubbles. It doesn't "just have to boil" it also has to survive being shut off, restarted, power outtages, and the most important thing is an alternative means to keep the media moving aside from air. Meds seem to alter specific gravity or something, most of us have used Prazi. This is not good for a reactor. Without a means to keep the media down in the water, the media surfs the foam right out of the container. Just dumping the water into the reactor from a few inches above seems to work great. More flow = better media tumble even without air. BUT this directly contradicts the flow rates K1 is designed for. It's not designed for the 10-20X flowrates raykeepers like to use on thier tanks. The reactors you buy run off much slower flowrates. Along with higher flowrates comes the media sticking to drain of the reactor. Real easy to reach disaster there too.... K3 is designed for higher flowrates but you give up surface area.
K 1/3 is designed to be used with thier bio chips..... Intresting stuff, bio animals that eat stuff up to like 5 micron?!?
The big deal with reactors is maintainance. It's the ability to remove all the "mum" by cracking a valve instead of tearing apart a bio tower or rinsing out rings. It's easy to clean which means it actually gets done and NOT slacked off. My rays used to get sick a lot. Everytime the filter appeared it could have contributed. Nothing wrong with bio towers or rings but if not kept clean then pores plug up, efficiency is compromised. Reactors knock off the ineffecient bio, only keeping new strong going, the rest gets sluffed off after it dies with the crack of the valve.
I'm a huge fan of the double sewn filter socks. I run the 100/200s but hope to incorporate smaller in the future after the 100/200s. Mcmastercar sells these double sewn socks. These socks take much longer to plug since there's so much more surface area. Just wash in the washer.
I run submerged meadia, bio reactors, and bio towers. Why subject yourself or your fish to the arguement of which is best/most efficient? Run them all and you're covered.
As far as the nitrate removal.... I'm willing to guess algae scrubbers will eventually shine. Pothos grow like crazy but don't seem to offer the effects we'd like without having a crazy ratio of plants to bioload. I'm willing to bet a "monster" size scrubber would offer crazy results. If we can get these to work then the drip systems can be turned down saving us all some on the waterbill. Maybe if we all start building them and share findings we could have them figured out in no time.
One things sure, with the shenanigans the utility companies are pulling filtration and this hobby are going to have to evolve or some of us aren't going to be able to afford keeping rays. Maybe we aren't far off from having to throw filter socks over Korilias and running giant makeshift HOBs.......
