0.5 ppm PO4
5 ppm no3
DIY co2, bottle changed every week. Don't know the ppm due to test kits being inaccurate.

I seem to have an issue with green dust and green fuzz algae. The fuzz is going away with help of exel (besides the fuzz on my moss, my moss is full of fuzz algae). The dust algae is really bothering me, I can't seem to find any information on it and I seem to be the only person I know that has this issue.
Now the problem might very well be co2, but as you can see I only have about 2.2 wpg over this tank plus I add a good deal of exel So I don't think my plants can really use any more co2. Most of my plants pearl every night before bed.

Currently I am not dosing anything besides csm+b twice a week with 50% water changes every Sunday. Every time I try and dose a little bit of either no3 or po4 I get double the algae over the course of one day. I've tried the ei method and it didn't work out. I just don't have the plant load and light or co2 to keep the algae from taking over first. I Think my test kits are faulty and giving me false no3 or po4 readings. So I rely mostly on my plants and algae to tell me if I do something wrong. I used to have every algae in the book in this tank and with messing around and observing I've managed to rid the tank of bba and green thread algae. All I have left is this dust and a Little bit of fuzz on my moss.

I was thinking of getting a UV Sterilizer and running it 24/7 and just try to kick up as much dust as possible for the UV to kill. Do you think this might help? Worth a try?
