All of you and this board in general have been immensly helpful in setting up our tanks! \n \nWe set up a 10G tank about 2 months ago and it is a beautiful little thing...we love it!!!\n \nI have a couple of questions about it though:\n \n1) We have these strange little white bugs on the glass of the back wall. There are a ton of them! They are tiny. Are they good or bad?\n \n2) There are slightly bigger darker colored but still very small bugs on the LR. Same question - will they harm the tank?\n \n3) Lastly, I just noticed on the LR are these things that look like white worms that are somehow baked into the rock. At the front of three of these white worms are these transparent things that look a little like tiny jelly fish. What are these? I might be able to get a picture but these things are tiny and see though...\n \nHere are some questions about the 50G that we are setting up right now. (10G was the "can we really do it?" tank). We set the tank up with about 50lb of live sand, 10lb of argonite and for now about 30lb of live rock. I think it is cycling but it somehow never had an ammonia spike. Ammonia readings are always at 0 but yesterday the Nitrite read at 20 and today it is a little higher than that. Nitrates are at 0.5 and all other parameters such as PH, KH, and SG are perfect. Would that qualify as cycling or are doing something wrong?\n \nThanks so much for any input!!!!
