I have an old pond that I've recently decided to get going again. Along with trying to research the old brand aqua-pure by pond wise, I think I pretty much have got it going. I just notice that I'm cleaning the skimmer every other day. The pump I'm using is the little giant w95. Its the more powerful of the other two that they sell. I also purchased a tetra pond UV light but have not seen any results. Not sure if maybe I needed a more powerful one. Suggestions would be grateful for what could be going on with skimmer and UV light. The UV light is the 9 volt from what I remember.
