I'm looking for a reactor to get rid of phosphates but currently something that I can also use Cuprisorb in to get rid of whatever copper I have gotten in there from my tap water (switching to Culligan water). I was thinking about getting the AquaC XP Plus Reactor but I have read some reviews about the lid not being very secure. One guy said he would not trust it outside his sump and another said that he starteded it and came back two minates later to a flood on the carpet. I have no sump so I would like a very good quality reactor that will not leak. Any suggestions on which ones are good?
