Ok, so my tanks been up for a little lass than a year. A few months ago I brought my first frag and became hooked. Fast forward to last night and I have my eigth piece in a 30 gal tank. My question now is what tests do I need, if any, to have these guys flourish. They all seem to be doing fine and none have died except for an incident with some nudibranches. Other than that theyre all extremely responsive as in they begin to spring to life even when the room light is on and even grab food when i spot feed. But, ive read here and on other sites people say some of their corals grow like weeds. Im thinking now i need to do testing and supplement with calcium, alk or whateve you guys suggest. Any suggestions in test kits or should I keep my setup how it is without any supplements? BTW, I have 1 gsp, 4 different zoas, 1 button, 1 mushroom and as of last night 1 pulsing xenia. See below for other specs.
