Actually it isn’t so bad. The first few months are subject to drastic change, but weekly maintenance is enough to keep it working. After about 6 months to a year it gets really easy. Only when something is going wrong is it actually really hard. Or if you choose particularly hard fish, inverts, or coral.Tbh I think getting a reef system has the very real potential to become the biggest fishkeeping mistake of anyone who doesn't have a work from home job (and even the potential to become that of some who do). It's just so sensitive to minor fluctuations in, well, everything.
