Purple Bonsai browning out a bit..thoughts?

[LoJack]

I did want to say good job, other than phosphates (which are the easiest to wander IMO) you have awesome param's, and the coral in your pics look super healthy.

I'm still tinkering with my levels because I failed to adjust my two part to take into account increased growth … and over time, what I was dosing wasn't high enough for what the tank was consuming.

I've slowly been increasing it, and I can already see negative affects of the variation. I know they'll snap back, but SPS are so finicky and yet the corals in your pics have clearly grown a lot and look really great!
