DKoKoMan's 150g Reef Tank

[DKoKoMan]

I recently tested PO4 at 0.16ppm but will have to get a new test kit for nitrate. I definitely agree that with the higher levels I'm not seeing my corals bothered by the higher values. I do want to get them more in the mid range levels. Do you think this can be achieved with biweekly water changes using RC? I am down to my lay pails (one opened and one full) so I can definitely transition to a different salt.

The draw for Alk/Cal on your tank makes sense to me from looking at your photos. I definitely don't have any ALK or CAL precipitating out. I will test the nitrate hopefully tomorrow. I'm due for my WC tomorrow as well so I can test the values later on. Thanks for the information tang daddy, hopefully I can get a handle on this.
