I seem to be having a problem with my tetra brand, 9 watt ultraviolet clarifier. It is rated for 1800 gallons, and my pond is just under 2000 gallons. So its a little over the rating of the clarifier, but not really. You'd think that it would just take a little longer. But I have a 2000 GPH pump, and I am thinking that the clarifier might not be having enough time to really kill the algae when it flows through it. Then again, you are supposed to pass the entire water volume through your filtration system every hour, right? So I have to have a pump that is flowing that much.
I am know the clarifier is working, cause I can see it glowing at night. Also, I put some algae killer in there and it killed roughly half of the algae. And, it has not returned. I think the clarifier is able to keep it at that level, but it can't seem to finish off the rest of the suspended algae. What should I do? Get another clarifier rated for more water volume and put that in line as well? Or is there some good algae killer that yall would recommend?
