Knobber, how big is your pond?
Can you do it from shore with ropes and two people? (Or you plus wife on ATV, etc.?)
The whole pond might be too heavy of a load to drag onto shore, so maybe make your "seine" only a 1/2-pond-width long?
P.S. I wonder how much of those mats grew last year and stayed on the bottom before your P-binder started to effect your water chemistry. Are you going to try it one more year to check the longer term results?
The pond perimeter is about 700 feet. I am thinking a much shorter seine length, like 25 feet at a time. Me at one end, and my son on the other. The algae is really heavy. Snow fence is cheap, so I can experiment.
I wasn't planning on another round of P-binder. This was the outcome. Seemingly very low orthophosphate all season long, yet plenty of algae. Now I am questioning the lab results. Disheartening.
Oct 11, 2024 - Pond water analysis by Natural Waterscapes
Orthophosphate = 0.06 mg/L
April 1, 2025 - I applied 3.5 gallons of MetaFloc to my 5.5 acre-ft pond per the label dosage recommendation
April 22, 2025 - Water test at a local laboratory
Orthophosphate = 0.004 mg/L
Summer 2025 - I applied several "maintenance" dosages of Ecoboost
October 8, 2025 - Water test at a local laboratory
Orthophosphate = 0.003 mg/L
