Pond was there 21 years ago when property was purchased. It hasn't had fish for the past 5 years at least, wasn't fished prior to then. It's always had watermeal for 7-8 months outta the year, so i figured that was the fish problem.

Max depth is about 10-12 ft in the middle. The only reason I don't think it has fish is there are no signs of minnows what so ever and no response to fish food.

I ran a water test on it prior to killing the watermeal with whitecap and everything turned out as follows:

Ph: between 7.5 and 8
Ammonia: between .25 and .50 (more towards .50)
Nitrate: 0
Phosphates: 1.0
