water chemistry help

[iceman86]

For lighting i have one of those 18-24" marineland reef capable LED lights. My tank is a 20x20x20 cube. Ive had it on my tank for 3 weeks. Thats also when i got those corals. Its a monti cap and a chalice that are bleaching.

As for phosphates im not sure if my kit is screwed because i tested my water and its 0.25 and im using r/o water and a phosphate reactor with phoslock. My city water also reads at 0.25 and i also tested my friends water at the same but he is able to keep sps corals so yhats why i think its screwed up.

The hottest the tank ever got over these warm days we have been having is 82.5 that i noticed.
