Here is a long overdue update. Been busy lately and haven't been doing much with the tank until tonight. 

I've been sick, we've been unpacking and my wife got hit in her car so that's a write off so dealing with that as well. She's fine, just was a bit shaken up.

Anyways, the tank has been going pretty well except for my phosphates which have been steadily climbing. 

Fish are doing well and eating. Corals for the most part are doing well. My forest fire digi is slowly growing and I can see a bunch of new heads starting on the frogspawn. My one acan is doing great, but the red one could be doing better. It always seems to never be fully inflated. I've tried feeding reef roids, but they sit on top of it. The other acan eats it perfectly fine. Any ideas on how I can get it to perk up?

I tested water and did a water change tonight.

Salinity: 1.026

pH: 8.2
Ammonia: 0
