Ok I want in. Had reefs for years and looking to do a seahorse tank. I have a spare 60g cube reef ready that I am designating for the job. My plan this far is as follows. 20g sump with refugium built in chamber for chaeto. Bubble Magnus protein skimmer, mag drove return pump with ball valve to control flow. This sand bad just enough to cover the base of the tank. 15lbs of live rock. Then as many non photosynthetic gorgonians as you guys can recommend for hitching posts. Cheap t5 light for viewing purposes only. Plan to let the tanks sit for at least a few months to build up my pod population. Monthly 30g water changes. Now comes the area I'm most ignorant.... What species is right for me and my tank? What flaws do you see in my design? How can I improve upon it? What should I be dosing/supplementing from a food and water quality perspective? I'm sure preference will drive the species to some Regard, I'm looking for this to be a successful operation the first time around but know that I am drawn to the colorful H. erectus variety but am not going to make my decision solely on what looks cool. Any guidence is appreciated.
