New Nano 65l Tank
hi, so got a new tank Monday, live rock in next day once water was to temperature.
Few thing I'm unsure of, the tank has a skimmer and 3 chambers and a return pump. Whitch is all underwater in the back of the nano in like its own chambers. So first question is where does the fresh oxygen enter the tank if it's all under water apart from the skimmer pump? Second question I here all these things about calcium and magnesium where does that come from? The water I put in?
Third is Is the tests kits only come with like 4 nitrate, nirate, ph and ammonia. So I need to test those 4 things so see if my tank has cycled. But what do I do if things are to high or to low. Does water changes put calcium back in the water there's so many things on the internet that seem to conflict on each other.! Any help with this would be very much appreciated
