My wife and I put in a pond last summer and we have been kind of battling over it ever since. To my mind, we have a HUGE amount of Algae in the water and I'm not sure how to fix it.
Stats on the pond: roughly 10'x12' with a sloped bottom, 3' deep at the deepest point. On one end we've got a skimmer with a pump and two removeable filters, the line out from this goes to a UV light we recently added, and then to the waterfall outfall where we have a bag(s) of lava rocks in the bottom of the tub that makes the waterfall.
The thing that drives me crazy:
We had to shut the pump off for a couple days and the water cleared up beautifully.
Turned the pump on, and the water goes green with a max visibility of about 8".
We talked to the local pond shop, and they suggested we rent thier "Big Blue" for a week, a mechanical filter (basically a 2nd pump, UV light, 2 layers of the green plastic filter and 7or 9 layers of a fine blue filter material in a 50 gallon drum. the water cleared up Great! Crystal clear water, I can watch the snails moving around on the bottom of the pond in the deepest part. The week was up, so I pulled the rented filter on Saturday and returned it.
Monday, Today, call it 48hrs later, I've got 8" of visibility again in the green water.
What are we doing wrong?
