So in my case and I restate in my case I just buy them and put them in the water and they live. The most difficult part for me is placing them as they keep falling off the first week or so. But after that it is only discipline .I do a water change every Saturday of 10% I use a very good salt and that is it basically. as regards the tank it is very good and handy ,it is only 120lt with a small internal filter of 1000lt/h a hang on protein skimmer,a couple of wave makers and about 175w of t5s.Apart from that I have no magic wands or miracle boxes ,All I have is some basic day steps to follow and weekly steps too and that is it .And btw the hole setup is only 200w excluding the chiller
