What size ultra-violet filter should I buy?

I have a 100 gal pond that has cronic green algee. I want to find the correct size filter. The water pump has a 350 gal per hour return rate.

What size ultra-violet filter should I buy?
1. You only need 8 watt for a 100 gallon pond.


2. Reduce the flow into the UV Sterilizer with a diverter - the water needs a minimum exposure time to the sterilizer to kill the algae and whatnot.


3. Be patient - it won't happen overnight. It takes about 3 weeks.


4. Make sure you keep the biofilter running. The UVC will kill the algae, but the filter removes it. UVCs are only sterilizers not filters...





You'll be pleased. Check Lowes or Home Depot - they have economical ones - under $100.
Reply:You should get a #4 70 watt Ultra-Violet filter.
