Hi I have a 25 gallon tank that has been running for almost a year and would like to add some coral but I;am completely lost on where to start. My tank has 2 clowns 1 banggai cardinal 1 skunk cleaner shrimp and live rock . My water parameters are temp78-sg 1.022-ammonia 0ppm-nirite 0ppm-nitrate 20ppm. I know my sg is low for coral what would be the best way to raise to 1.025? My filter is a hob. I have been looking on the internet for info on how to care for coral but get more confused. What kind of lighting would you suggest for a reef tank. I just don;t want to wast money by rushing into it. Thanks.
