O.K. crucify me now I have been using prime water conditioner since I set up my tank. Purchased anR/O unit today ( Thanks bhill). I was wondering if there is any point in still using it? BTW the 110 she has for sale IMO is worth every penny she is asking for it.

nope

Some would question whether there was any benefit to using it in the first place.

I use Prime in my FW tanks. I sure feel weird pulling out a needle/syringe and measuring 0.5ml for the small water changes...

Well I was using tap water and never had any water quality issues or lost any fish or softies.. Maybe I will use it for my FW tanks till it is all gone. Thanks for the help.
