What do you recommend for a pond that only has a problem when someone goes swimming? I imagine treating the whole pond won't help since the deeper water doesn't get stirred up?
I don't need the alum to treat the whole water column and settle anything on its way down to the bottom. I just need to treat the mud on the bottom which is why I thought dry broadcasting might work, but I don't want to waste money on something that won't help.
I have 5'+ visibility now (no algae bloom yet) so I don't have an everyday muddy issue like some have. Would lime or gypsum be better?
Treating the area by dry broadcasting will not hurt anything...I just don't know how long it may help. Ag Lime and or gypsum add minerals to the water and won't help with what you hope to gain.
If you have several kids and critters feet sloshing around in mud and clay, there really is no way to avoid muddying the water.
