I wish i still have pictures of my old sea grass tank, it was my sea horse tank and the only pictures i have left from back then are from when my seahorses (Kudas) were in the quarantine tank with some feather caulerpa and LR.
I use a Turbo Aquatics Algae scrubber, they are built excellent, they have great support from Bud Carlson. Algae scrubbers are the most underrated items in the hobby. I assume an algae reactor would work the same because it is basically a different form of algae scrubber
