Phosban and rowaphos are very similar if not identical. Their advantage is that they wont leach the phosphate back if left in too long. Both would work in the reactor. I would say 4 months or more depending on what the phosphate level in the tank currently is. I have been running one for 6 months now and between it and the cheato, there isnt much of a problem with algae growth. As a matter of fact, the chaeto isnt growing all that much lately.
Chemi-clean will work on the slime, but unless you work to constantly get rid of the nutrients, it will come back.
You dont want to get any of the media in the tank. Best thing to do is flush it out before the return line goes into the tank or put it in a fine mesh bag and rinse in the sink. You could probably do pretty well by using a bag and putting the media in a hang on filter, the reactors are nice but are probably a bit overkill. As long as the media has a reasonably good water flow through it, it should work well enough.
