Green Water :(
 

Set up my new tank about 5-6 weeks ago.....got 2 percs and a clean-up crew in there now. Major green water issue all of a sudden. I figured that my new lighting was too close to the surface and getting the water too warm, so I have since moved it up. LARGE water change and left the lights off for a couple days and things were REALLY clearing up, so I turned on the lights for 4 hours yesterday and came home to pea soup again. All equipment is in my sig. Any comments or tips on how to get rid of this?

Where's your water coming from? Considered a UV Filter?

Water is RO from a bottled water company. Guaranteed to be less than 10ppm TDS. I have a large uv on my freshwater tank running off the filter pump, but no pump to run it on my reef. Don't REALLY wanna go buy a pump for a few days of UV. Is this maybe just a cycle that I should try and wait it out.

Are you dosing any chemicals or feeding too much perhaps? I would just wait and see what happens as you mentioned and carefully monitor everything in relation to the tank carefully till it goes clear again..

i had the same issue i got a uv filter and cut back o feeding and problem solved

I had a similar issue a while back,

Just seemed to happen like overnight the water turned green and murky. I just waited it out.. took a little while like a week but cleared right up. My soft corals and zoanthids all loved it, I think it provided a ton of food for them as they all looked fat and happy when the water cleared!
