Diatoms=Cleanup Crew

[jcs69]

I've gotten my first bloom of diatoms and I'm in my third week of my N2 cycle. My ammonia spiked and is dropping, my nitrites are up and dropping, and my nitrates are at 15. Should I add a cleanup crew since I've got diatoms. I've heard once you have diatoms it is a good point to add a clean up crew?????:notsure:

Not until all the above levels are at 0. If not, your clean up crew can die.
