Cloudy tank issue

My tank has been setup for about 2 months now and is doing well. Plenty of fish and plants of all kinds. It's a 75 gallon with a eheim 2217 and Fluval 404 running bio media and sponges. Pressurized CO2 with an aquamedic 1000 reactor is attached inline to the eheim. 260watts of PC.

After having it setup for about 3 weeks I did my first 50% water change and all went well. But then 2 days later the water started to get cloudy. I thought maybe it was a bacteria bloom so I let it sit until it filtered out clean which took about a week or so.

The problem is now everytime I do a water change the tank does this, gets cloudy, not REAL cloudy, just slightly hazy, enough to be annoying but not enough to keep me from seeing the plants or fish. So next time I limited my water change to 30%, same problem. Now it seems as though the tank is just constantly hazy. pH, amonia and nitrates are testing fine. Any ideas on whats causing this? Here's some pics:

How are you doing your water changes? Try not to just dump the new water in, but do it slowly and make sure that any debris from the substrate doesn't get stirred up which can cause the water to become cloudy.

The substrate doesn't get stirred, I generally pour it into a bucket, add tap water conditioner, then use a maxijet 1200 to pump into the tank. I just ran some searches and some have recommended temporarily adding a UV filter, which I happen to have laying around. So I added an 18 watt UV to the water path of the eheim (tank-->eheim-->AM1000-->UV-->tank). I'll give an update tomorrow.

Looks like greenwater to me. Your UV should clear it in less than 3 days.

Cool, I hope so. At least this motivated me to plumb the UV in last night so I can kick it off and on when needed. Now to hide it all in my cabinet!

If the UV doesn't work, try cleaning your filter...it may be the problem (that was my problem)...but I am pretty sure yours is not filter related because it happens a few days AFTER you do a water change.

looks like it has a green tint.
Ever notice your plants grow better after a water change . So does green water.

Ahh...well I'm on day 2 of the UV filter and the tank looks a little better. Now I'm trying to figure out which new fish I put in the tank is attacking all the rest.

While the UV sterilizer will kill the green algae, it doesn't remove it, and your regular filter may not be able to do the job either. If you can borrow/rent a diatom filter, the clearing process will go much faster.

Well, the tank looks much better. Thanks for all the advice. CherylRogers: I'll find out durring my next water change tomorrow whether or not it got rid of it or not, but I have a fluval 404 + eheim 2217 running against it, and I put carbon in the fluval for the week, so I'm hoping I got rid of it.

Here's some pics:
