If need be, we will rake and start sweatin' in the future. But, for now its only minor growth.

I looked at the invasive fish list for WA state. Looks like black chin tilapia is a no-no. Dunno about specific regs. on other species of tilapia. I think if it was warmer in this area, and the regs permitted it, some kind of tilapia would not be a bad choice as food fish for my buddy to plant.

I was wondering if ya'll had any other good ideas for a cover (submerged plant) for deeper areas of the pond? We were planning to go with some kind of native hornwort, but open to other suggestions.
