I have had a 180gal FOWLR tank for 6 months. I now want to start adding coral and have just added a small one. I have been adding kalk and supplimenting it with Ca, Strontium and Iodine. I have bought a reef test kit that tests for Ca, NO3 and PO4. Do I need to test for anything more...

A friend of mine has a 40gal fw community tank. It includes platyes, sword tails and Mollies. She has had the tank setup for about a year now. She currently has one fish left from the original ones. The second to last one just died today. We are just wondering if this is common - what is...
