Hi, new here. I did a search and nothing really answered my question.

About 10 days ago I put in cured live rock and damsel to cycle the tank, I have been testing everyday and have not seen the levels rise at all. Also the fish seem to be doing great. My sand is turning a brownish color I am guessing this is a algae/bacteria growth? I do have some tiny spots of coralline growing. So my question is can the cycle ever be so fast that you do not catch it with tests? or I am still in cycle. I do not understand how I could still be in cycle with the growth of coralline etc? Help please.

20 gallon
Fowlr
salinity 1.023
2 damsels
fiji live rock 15lbs

Cycle could be over only if you used Fully Cured Live Rock. If you didn't then I'd take a stab and say your still in cycle. Looking at 4-6 weeks. The Brown algae are Diatoms growing. If you have Coralline growing already, then your ALK MAG CA must be correct. What test kit are you using fo your water?
