My cycle has been going for about 3 weeks now. Yesterday I noticed green algae beginning to grow on the sand and the rocks. Is the green algae normal, because I thought there was supposed to be brown diatoms first, which I haven't noticed? I have 85 lbs of reef bone, and 80 lbs of play sand ( I did the vinegar test with good results). The shrimp has decayed almost completely. The ammonia is around .6 mg
/L, I tested about 4 days ago, and used the last of my test kit, so I need to get another test. The nitrate is 10 mg
/L and the nitrite is .3 mg
/L (both tested last night). Should I add anything into the tank to help with the cycle, or does the shrimp provide the neccessary bacteria? Or should I get a piece of LR
to add, because the bacteria is already established on it?
