I will be setting up my first Marine tank in the next few months and can't decide whether to splurge on an RO unit or just go with treated tap water. My tap water is hard and has a ph of 7.6; so my initial plans were to add Seachem Prime as I do with my FW changes, obviously salt, plus a marine buffer. I use Algone and Purigen in my FW tanks and find these unparalleled in there Nitrate control; I was also planning on running plenty of Phosban in my cannister filter. So surely I have addressed all the main problems with tap water. My neighbour ran a SW set up for a couple of years using just tapwater and Prime occasionally he would buy some RO water if he was at the lfs but wouldn't make any special trip for it and his fish did fine also he had very little problems with algae and he hasen't heard of phosphates and never tested for NO3 lol hadn't a clue what i was talking about when I asked him.....
Going to take a lot of persuasion to get me down the RO route as space is also at a premium; I will be attempting a Reef system in the next few years all going well then I would get the RO unit as I know Corals are very sensitive to water conditions.....
