No, not yet. I haven't turned up the temps in the tank yet...running about 74 degrees. I'm fighting ammonia start-up problems which I expect/hope to get under control soon when the ammonia eating bacteria on the filters start really kicking in.

Finding the right balance in your pond is tricky...I like to have some vegetation, but not too much. Of course, we all like lots of forage also. Depends on how many predators you have and water quality, etc., etc. You may want to step down gradually and see how it goes. I've been playing with the numbers for 4 years in my ponds and think I'm about getting to where things need to be...until some disaster comes along to throw everything out the door!
