Well, I wanted to start a reef tank for years, so on a whim I bought a RSM 130 and set it up. I filled it today with two bags of Carib Sea agra alive substrate, salt water and turned on the pump and heater. I left the protein skimmer off. The SG was 1.024 on the Milwaukee meter and pH was 8.2. Other than that I just don't know. I literally know less after reading forums for a couple of weeks than I do now. The water is cloudy, but that was expected. The RSM has a black block sponge and a bag of carbon in it but thats it. In addition to that, I have a couple of red sea test kits, a Spectrapure max rodi manual flush coming, a water change device, another power head.....any thing you want to add, feel free. I'll take some pictures once things have calmed down. What tests should I do before I add live rock? 78F is okay? Have some little bubbles. what would you do next? Thanks in advance for any and all responses Mark
