Seahorse tank w/macro algae ideas?

[Rickybobby]

Hey guys. So I’m going to order a Waterbox tank for a pair of dwarf seahorses. It seems macro algae gorgonians and my Kenya tree corals I have will be great for this and for them to hitch. Should I use ai prime freshwater to do this? Tank will be 30 gallons? Also thinking of a mangrove as well?
Basement is always 22c so a heater will be needed slightly. Also will run a uv sterilizer.
many macro algae suggestions? And will prime freshwater work properly?

Just watched this. But he’s new to this. I’m wondering what the experts are doing on here

Have you had any luck on this? I just got a 5 gallon and I’m looking to do something similar. I want a natural environment for them and not a bunch of plastic.
