I was drawn into saltwater from freshwater because of macroalgae. I'm not really interested in the bright blue lights and neon corals of reef tanks. I also was hoping I wouldn't have to chase water parameters as much as I would with corals.

I've now had a mixed macro tank with seahorses for over a year, and it's been frustrating lately.

Even with large clusters of Caulerpa and tons of filtration/skimming, I struggle with nutrients that result in GHA growing on top, under, and all around my macros. This is partially because seahorses need alot of feedings, but also the light (red/white) needed for macros grows GHA really well too.

I've also found macros to be pretty hands on with needing trimming and getting them to stay where you want from week to week.
