Hello All - I have been reading on this forum for awhile now. The expertise here is awesome. No doubt I am learning everytime I read. I am new to the saltwater arena and have a host of questions which I expect you-all have answered many times. Thanks in advance for indulging me as a new person on the saltwater block. My school has allowed me to purchase a Marineland Instant Ocean setup which comes with a 55gallon glass tank, an emperor 400 biowheel filtration unit, a light strip with 40watt bulb, and a 200watt heater, along with test kit and hydrometer. I also bought to begin with - 15lbs of carib sea - aragonite -reef sand and 40lbs of live aragonite - reef sand. I will also get about 75-100lbs of live rock. So, is it "ok" with you-all to start with the newbie questions? Thanks....
