Water Chemistry levels

[JenniferL]

I have recently upgraded to a 90gal tank in the past couple weeks. All new RO/DI water used in the new tank (was using tap water in the 55gal).I use IO salt. My water readings are listed below. I know they are a little low, but I am confused as to what product I should use to boost them up a bit. I would like to try some of the SPS later on and thought it might be a good idea to make sure my water is up to par before going that route. Right I just have T5 HO 4x24W on one half of the tank while I wait for my new lights to come hopefully early next week. I will be getting a Metal Halide fixture 2x250W with moon lights.
