filterless system

[hummer]

Everyone has their own type of setup but a good skimmer, live rock, power head and phosban reactor is all I have in my system. I guess a phosban reactor does whatever you put in it. I put Carbon media in mine to remove toxins and it clears up the water. I bought mine for about $50. You would also need a pump (Max Jet 400 maybe?) to push water into your phosban reactor and back out to your tank. If you have a sump, you can tie it into the existing pump.
