I am thinking of running phosban. I am not sure what size reactor i need. I saw ones that will run 150 gallons ( i think), but i have a 175 bow, 90 gal fuge, 100 gal sump.
I actually want to double whatever it is, and run carbon and phosba.
if your worried about it only doing 150 gallons buy 2 of everything you need .... but remember dont go crazy trying to reduce phosphates all at once it needs to be done a little at a time not to shock anything ..
Don't need it drilled. It can sit on the lip of the tank (in back for appearances) or on the lip of a sump, etc. The small minijet 404 sits in the tank to feed it.
