A friend of mine called me up yesterday and he informed me he recently got a 150g saltwater tank. It is a week old, and he already has a 8-9" bamboo shark, 5" diamter stingray, three yellow tangs, one 2ft dragon moray, one 4" clown trigger, one 4-5" volitans lion and three or four small damsels. And its only a week old! So I went over to his house and tested the water. pH and salinity are good, nitrates are zero, but as expected the nitrites are above 1.00ppm and the ammonia is somewhere between .5 and 1ppm according to a red sea test!! I don't know if the cycling is starting, or if it is going to just get worse and worse and totally crash. What should I tell him to do? I am thinking do another test tomorow and if it is better then just let it be and take its course naturally, but if it has gotten worse then do a big big water change to save the critters. I know this will throw off the cycle, but its better than everything dying. Do yall agree that is the proper thing to do?
