hey Mike, I was thinking about skipping the pump for the reactor all together, and just use the effulent from the CA reactor to provide water to the rowaphos reactor.
im not worried about the po4 from the CA reactor I use ARM I just did not want to run another pump back there.. (last time i counted I had 13 plugs for differnt things back there...)
How long can I expect the rowa phos to last if I have .25 (salifert) of po4? Im debating if I should buy the 5 liter bucket for 266 bucks or the 1 litter...
do you see better growth on the SPS? and no algea? what would that do if I had a bunch of cheato in the sump?
Thanks for you help...

Sorry, I'm really not that much help
I use phosban, simply because it is easier for me to get. However I use half of the recomended doseage in my tank (Rowa and TLF recomend different doseages for essentially the same product, I don't understand it). I have never tested my tank for phosphates so I really have NO idea at all how long it would take for it to go down. I don't see better growth, I do see less algae (perhaps because I went barebottom however?), I can barely grow macroalgae anyways, so I'm not really sure what the chaeto will do, my guess is that it will have little affect as chaeto probably is limited by nitrogen in our closed systems as opposed to phosphate.
My only real advise is to start out with a small amount for the first month or two. MANY people that started out with the full dose experienced serious STN issues. not sure what caused it, but most likely rapid changes in water parameters from dumping a half pound of iron in their tanks. You can expect changes in alk, as well as phosphate and clouding (iron dust) issues if not used lightly.
As far as adding another pump for the reactor. you can either try running it passively first (I'm having good luck with this). OR you can try tapping off the outlet of another pump. IE just put a tee fitting on the outlet of your feed pump for the Ca reactor and have it feed the rowaphos reactor as well, use a small ball valve to regulate. Protein skimmer feed pumps could work as well if you have a recirc style skimmer with a lower flow pump.
I just don't think you will get sufficent flow through the media if you stick the reactor on the outlet of your Ca reactor.
