Professional installer only put in a skimmer
I had a pond put in last fall by a professional pond installer. I think it is about 1,000 gallons. I told him I planned to get fish. Until recently I assumed I had everything I needed to run my pond. Within the past weeks I have had some cloudy water, some algae bloom, etc...I've been to the pond store and have been educated on the bio filter and have purchased a few chemicals to help with beneficial bacteria growth. Recently I started learning more and decided to add a bag of lava rocks to my skimmer. I thought the filter was simply the 5 black brushes in my skimmer. I have a Little Giant skimmer model. So--as I'm learning more, I'm discovering that the pond guy should have put in a second filter box thing near my waterfall where I could have put the biological sponges/rocks/AC etc... So---I'm angry and concerned since I just added 4 little comet guys yesterday. Surprisingly, the pond has amazingly cleared up in the past few days. i can acutally see the rocks on the bottom that I have since learned that I should get rid of (!)The only real problem I am having is a brown color that is evident when you look in the pond but is not evident in a clear glass of pond water. I put in AC anyway--where else but the skimmer--but I do not know if there is enough flow through there to utlize the AC or the lava rocks. What would you guys do with this issue? My pond is in direct sun but still gets a lot of poplar leaves and flower blooms from above.
