Hello everyone
I am new and I am just going to lay out to the experts my most recent encounter with ponds. I have just started as an Aquatics position but I did not investigate before I took the position. I have been able to get the chems under control in our pools and spas but I am having a heck of a problem with the ponds. The biggest concerns are that this company gives me around $400/month to maintain 5 ponds that are about 100' X 50' and 15" deep. They have motors to circulate the water but no filters. When it rains, the drains are pointed into the ponds so a lot of dirt are in them. I noticed that there is a film on the bottom about 1"-3" thick and it should not be disturbed because a black cloud will form. I thought I had it figured out when I treated one of the ponds with a large amount of cal-hypo as suggested by a Leslie rep. It was cloudy brown for a few days but then it cleared up pretty good but not completely given that it was dark green to begin with. On the 7th day I added a pack of Otter Blue Shield and it gave it the sky blue color that the manager was looking for. The problem is that it only lasted about a week. Now its dark green again. Another issue is that this is an apartment complex that houses about 800-900 adults and CHILDREN which love to play and throw trash in the ponds, pool, and spas. There are also pine trees around these ponds and it seem that they let off something new every other week in to them. I will have been fighting with these ponds for 3 month next week and thought I would have figured out by now. I was wrong. Can anyone correct me?
Thanks
