Aquashade/most aquatic dyes won't hurt marginals/lilies. They will deprive
the underwater plants of needed light, but won't kill them, only inhibit
them.
If they are using algaecides (simazine/aquazine, etc.) however, they will
hurt/kill the plants as they are herbicides. The amount of damage to the
plants will depend on actual dose the plants are exposed to, and duration of
exposure (as well as type of herbicide).
It would be nice to try to get together with all your neighbors, and
everyone agree to plant marginals, lilies, etc, and all agree to suspend
any/all use of the herbicides, which accumulate in the soil over the years.
That plus proper stocking of fish (maybe with sterile/triploid Israeli carp
who will cleanup a great variety of submerged growth), should lead to a
chemical free, balanced pond that will no longer need even the dyes.
I've been there and done that. It took a couple of years to balance, but now
we have chemical free ponds (2 one half acre ponds), surrounded by blooming
lilies, and marginals.
It will be worth the effort!
happy ponding,
Greg

I'm not sure...I don't think they use much (it's treated four times a
season)

The dyes will not affect the plants you mention. What is used to
treat the algae, and at what rates?

We just moved to a house where we share a 4 acre pond with a
few other houses. I'd like to plant some aquatic plants such as
Pontederia and Lily Pads.. This pond is "treated" for algae and such
and dyed a few times a year. Can I still grow some of these plants?
Thank you very much for the help!!!
