Just got back from 10 days vacation and everything looks good for the most part, no corals lost but my royal gramma and one of my pyjama cardinals is missing. I'm hoping the gramma is just ****ed off and hiding somewhere, I've had him for almost 4 years

I didn't have high hopes for the cardinals as I bought 3 of them and they were having difficulties with the current and hiding next to the wavebox in a low flow area. As a result they need target feeding and well, they're pretty stunned fish.
The tank will need some work, it hasn't had a waterchange in about 3.5 weeks and the coral coloration isn't as bright as it used to be. With the reactors all offline the algae growth has surged and I see bunches of caulerpa and some sort of other algae which I know the name of but I'll be damned if I can remember which book I saw it in.
No pictures, I just finished working on the tank for about 3 hours and my back is done.
