The main reason the tank does not have fish yet is acquiring the 40 youngins from the same clutch at a reasonable price.
As far as maintaining the bioload, the less equipment the better imo. Going to experiment with both methods, mechanical and full biological. Using macro algae as a natural absorption and removal method, along with slowly getting my 55g converted to Xenia, for pound for pound nutrient exportation.
Right now the tank is auto fed 4 times a day with flake food, and twice a week with shrimp blend for the anemones. I'm hoping the biological and bacterial filters for this tank will be fine, with a small clutch of fish gradually getting larger, the system should be able to adjust at the same rate in theory. IE my display macro will grow faster, sump caulerpa will grow faster, and xenia should grow faster.
The only material I will run heavily though is carbon, and most likely double to tripple the recommended amount, with the nems and xenia and allelopathy being my biggest concern.
Most of what I setup is just theory though based off BRS's Harem, and my personal experiences with nems/clowns in all my tank builds, and from what I've learned regarding territory disputes and hierarchy resets with wrasses. I've artificially doubled fish populations in my previous tanks by putting a large mirror in front of it, for me this has helped get rid of aggression on fish being singled out, and actually resets the hierarchy and has allowed me to add additional fish without issue. Should I lose any clowns at anytime, this is how I plan to introduce more as replacements.
