Scum problem in my pond - need advice
Hi,
For the last couple of years, I have had a 100 gallon pond (moulded black liner) where my Koi have successfully bred. This Spring I have encountered a small, annoying problem. There is a furry deposit on the sides of the pond - probably algae? that easily flakes off and is being stirred up by the fish, forming a large amount of floating scum daily. It is easily scooped up but accumulates a large amount of sludge throughout the day. The pond water is clear as I have an ultra-violet light and a filtration circuit. The local pet store said snails and a sucking pond fish may help but the water was too cold to use them, however now that the weather is warmer I will give this a try. I would be interested in any on-line comments or solutions if anyone else has had the same problem. Thanks, Tony Vancouver, Canada |
