I have a 29 gal tank and i was recently told that i needed to do a water change because i've had it set up for a few weeks and some algae is starting to grow in it. I've never changed the water before so i really don't know what i need to be doing. The salinity is a little high now so i'm afraid that if i take out some of the water and add more saltwater i'm going to mess up something. Should i even be using saltwater? Or do i take some water out and add RO water back? Also, how much water should i be taking out each time i change it and how often should i do this? Thanks
