I've been running carbon in a phosban reactor for some time, but I started to realize that the water had taken on a very yellowish hue. (it sneaks up on you!) I decided to double the amount of carbon I've been using. After shopping for a larger fluidized reactor, I finally decided that multiple phosbans were just easier to deal with than one huge reactor.

So...here's my collection of phosban reactors. The two on the right are running carbon and the one on the left is running Rowaphos. The addition of the 2nd carbon has made a big difference in the water colour. That's about 500ml of carbon running in two reactors. The reactors are supplied with a MJ1200 in the sump. They are NOT plumbed in sequence.
