tl;dr version: Help Seaslugteam design a 40g breeder frag tank that does not care about aesthetics. long version: In this journal, I would like to have an open discussion regarding how to build/design a 40g breeder frag tank which I will eventually build over the next 6 months. Each post will include a new topic regarding reef keeping ranging from lights, water params, etc. The end goal is to have an environment that is very good for growing out the 'easier' coral such as zao, palys, lps, shrooms, etc. without caring much for how the tank will look. Of course, ease of maintenance is also an important factor.
