Hi I'm in the process of setting up a new tank. I have a jewel trigon 190l tank which I so far have 20 kg of live rock and 5 kg of live sand and I also have an external filter running and a skimmer. My tank has salinity of 1.23 and is 26 deg c in temperature. I have 2 t8 marine tubes a white red and a blue 1 running and an led blue tube. It's been cycling a week now and I'm taking my first water sample to my lfs today for my 1st test. I'm a marine virgin so please any advice would be great.
