Where copepods coming from?

[Yuki Rihwa]

A little history of my tank. I set it up with dry sand, dry rocks little bit over a year ago with fish only tank, I'm only turn on my tank light when I'm home and it's on around 4 hours max, I have no problem with diatom or algae whatsoever! About a month ago, I converted my fish only tank to Anemones tank and upgraded my light system to support my Anemones and the light schedule is on 12 hours a day, I started getting diatom bloom and my turbo snail keeping the rock clean most of the time, few days ago (night time) I saw my water become cloudy (light milky white tint water) and it's cleared up in the morning (I tested my water and everything are stable nothing change), my Anemones look fine like usual, the only thing strange that I started seeing a lot of copepods on my tank glass and I didn't introduce them in my tank, not like its a bad thing because I was planning to keep a mandarin later on but I wonder where are they (copepods) come from?

Anything moist that you add to a tank and that includes Anemones has the potential to introduce pods.

I'm having the opposite problem....NO pods. I add to my system from LFS every other week. Also having issue with chado. I'll buy a couple softball size handfuls and within a month it's gone
