MK70 good to hear! I would do what Cody says and go ahead and start it up. Just take it real easy. 15 to 20 mins a night then 30 for a couple of nights if you can I would put it on 1 hour for a couple of days then 2 hours for 2 days and 4 hours for a week then 6 and stay at 6 for a while. Don't get in a big hurry to run it all night long. I ran mine on 6 hours for a couple of months the first year. I can't remember how old your pond is or how big but I wouldn't push it just take it easy and start giving those fish some much needed D.O. Good luck bud let us know how it goes ok.

The only difference between a rut and a Grave is the depth. So get up get out of that rut and get moving!! Time to work!!
