Green slime, tank upgrade

[steallife904]

I upgraded my 72 to a 140 a little over a month ago. This week I started to get an outbreak of green slime looking algae on the rocks and some on the sand. I am wondering if this is just a mini cycle? I used the live rock I had in old tank but added some pukani dry rock and all new sand (dry sand). Is this my tank just adjusting?

My P04 = 0
nitrate= 0
KH= 7
cal= 440
My ph has hung around 8.2

also note that I have 2 xf150's for flow. they are both set at 40% (they alter coming on every 30 minutes). I may dial the flow up to 50 and see if that works. At 40% though they really push some water.

It sounds like Cyanobacteria, but I agree, your tank is probably just rebooting so to say. Manually remove what you can, keep your parameters within reason and try increasing the flow as well. GL.
