Alright let me start from the beginning. My husband has tried over the past 3 or so years to keep a SW tank. I will say things NEVER went well because we rushed EVERYTHING. We would set up a tank and within 2 days stock it with fish. Yes we know HUGE mistake. It has been about a year since our last tank because we gave up. We should not have giving up because honestly our failure was out fauls to begin with. Lets start over. The other day we were given a new in box 29g Bio cube that the in-laws we going to set up and never did. We decided that we wanted to try again at SW. We went and bought 20 pounds of live rock and 20 pounds of live sand yesterday along with some salt to start it up. We are using RO/DI water and as of now have the tank set up. For lighting we have 1 36 watt 10,000k and 1 36 watt Actinic bulb. The temp is 77.4 and the salt is 1.025. We would like to put in a few corals some day when the tank is ready which we know is not now. My question is I have seen people post they used a piece of shrimp to help start the cycle. If it would help we will do the same as well except we dont know what kind of shrimp or where to get it from which is why we are asking. Thanks!
