hello, im new here. i made a problem with my pond this spring when i changed my filter media in my mechanical filter from fine 2in thick pads to matala. and i changed from river rock bio filter media to bio balls. it works great, i dont have to mess with it near as much. i didnt think about all the fish eggs that my old system caught in the media. now alot of the eggs just go thru everything and end up in the pond again and i get hundreds of babies. has anybody had this problem? draining the pond is out of the question, its to big and it would stress the heck out of my fish tryin to net them up. some of them prob weigh 10 lbs or better. i fished about 150 of them out this summer with a very small hook, a shad net doesnt work to well either, they see it coming a mile away. any advise? thank you
