I need some expert advice on controlling unwanted algae and weeds! I have two types of weed problems going on currently. The first is Sago pondweed or at least that's what the guy i sent samples to tells me. It's only a problem in spots around the pond although even though it's a rooted plant it somehow seems to come loose and gather in huge clumps and float around top water making fishing nearly impossible in some areas! The REAL problem i'm dealing with is Filamentous algae. In the last week we've had temperatures of 94 degrees and just over night i have nasty neon green bloom covering 3/4 of my pond. VERY aggrivating! The aggrivating part is that I run a Vertex bottom diffuser systems in my pond 24/7. I have 10 grass carp stocked on my 3/4 acre pond. I have added beneficial bacteria, i keep pond dye in it and even try to rake the floating mats out when they blow to one side of the pond (which seems to be highly ineffective!) To really rub salt in my wound the pond about 200 feet across from mine that has zero areation , no maintenance and is just a natural farm pond is crystal clear and very fishable??? Go figure?? Can someone give me any ideas what to do? I realize i can use a copper product and kill it , sink it to the bottom and wait for it to rebloom all over again but i'm looking for a real fix...possibly a way to get rid of all these nutrients or find a product that keeps this thing in control before it ever has a chance to get out of hand! I have pond completely stocked and would love to fish, however there isnt a clear spot on my pond to cast so i'm assuming fishing this year is over until late fall. Thanks in advance for someone who can help with this aggrivating problem!!
