Thanks for the replies.
We have undetecable readings on both nitrates and phosphates and currently use ChemiPure Elite (in a bag) and PhosLock (in a bag) but both have always been in a very, very high flow area of the sump so that water passed through them. I do agree, that just plopping them in the sump isn't the best idea, but with correct water flow, I've never had an issue.
We might just go ahead and do the Phosban and carbon in a reactor, it's not like the phosban is that much money.
Our calcium is always all over the place. It's the one number that is never stable, it's always high. Alkalinity, Ca, Mag and Strontium are all where they need to be, but Ca likes to float around from 400-500. This doesn't really bother me, since it never goes low and frankly I've just given up after numerous replies from people on what to do and nothing really worked. He wants to do the Calcium reactor because someone told him that this would keep our Ca level consistent. The money isn't an issue (well it is, but I don't want to loose thousands of dollars in corals either, hahaha). I guess the real argument is that I don't care for SPS all that much, and he would load the tank with it......
