Lately I have started to ponder if I should get or start to buy everything for one. However I am confused on all the different types and equipment that goes to one. My tank is havily stocked with LPS and completely covered in coralline algae 3/4 of the walls. I tested my water for cal and alk and alk was 13.1 dkh and calcium was 390 ppm. This is what starting the thought process. What should I look to start buying or getting for one of these? What brands should I look into or not even bother.
