SPS and Phosphates

Question:
Should I switch to RO/DI water? What unit? And will this cause and algae problems switching my water source?

Synapsis:
Over the last month I have been keeping a close eye on my tank and tweeking many things. I have been monitoring levels on a day by day basis and working on getting everything perfect. From lighting, filtration, to growth of my corals. Basically finding the perfect water parameters and keeping them in check. I decided to test my tap water(What I use for my tank, sadly) and found out after mixing 4 gallons that my phosphates are 1.0 before I even add it to the tank. Now I going to a full blown SPS and know that phosphates are a major concern when aiming for healthy growing corals. I also have had a slight hair algae problem and until now have got it under control and got rid of it. I think the main problem may have been my water which i change out 5 gallons weekly.

Changed:
Tuesday I will be adding a BRS reactor with GFO and at the moment i change my carbon every 2 weeks, which I started 1 month ago.

Need some tips on managing the perfect SPS
 
Let me answer this. YES you need an RODI unit, or at least RODI water for your reef. You'll find being successful with SPS and tap water near impossible.
