Hello everyone, I have been looking at a possibility to get a 120-200 gallon reef tank for my apartment, however I am a bit of a loss to get my head around all things I have to consider for this hobby. I have been googleing around but I find myself finding questionable articles about reef tanks and contradictory information in many cases (not on the most important aspects of a reef tank but on smaller ones). I would be thankful for some links to the things that someone getting into this hobby should know (I think I got the MUST know part by now). Things I have read about (thou not in huge extent) are: -Apartment requirements for reef tanks (mostly floor strength, floor capable of containing the water and/or draining system to avoid flooding my neighbor, location to avoid direct sunlight/keep it safe). -Basic equipment required to keep a reef tank operational (here I am a bit confused, some sites have more than others). -Basic costs (electricity, supplements, foods and additives, equipment replacement) -Tank population (Here I saw stuff like the questionable 1 inch fish per gallon. There is no way to accuratly test this, but my tank is going to be fairly light on fish (no more than 50 small ones EVER, no big ones at all, I expect to have 20-30+some cleaning crew if its effective+reefs). -Basic Maintenance (Ive read a lot about this but everywhere the information seems incomplete, I am looking to create a low maintenance tank if that is possible, if not, I want to learn more about the biochemistry of the ecosystem to make sure I understand what I am getting into). Currently my plan is to give it a full year of reading and saving cash until I am confident that this is the right move for me. I have other interests I pursue so I wont be ONLY reading about reef tanks for 1 year, but I want a very good understanding of all the parameters I need to know, and for that I need a lot of material. One topic I have not seen too much about is quarantine and medication of sick fish. Kind Regards, Cats_Paw.
