LOL wow I have been away for too long, luckily I have all the aforementioned animals to potentially contend with but the only ones who ever pose a problem are the rabbits and only when it gets colder. I put chicken wire across the holes by my gates in fall, but I already had a rabbit inside. I trapped him, moved him out, but he found a way back in 2 times before I hauled him miles away to let him go. He had a nice little home under my deck, will post pics of that in due time. I've still been tweeking the pond, but my second daughter is now 18 months which has considerably limited my time for other things, but I did manage a few tweeks this past summer and will post them over the next several days. I got rid of the corrugated tubing I had running through my old Jabao Filter (same one Jason on here is having troubles with, mine never leaked, I just wanted to go all natural and take it out); and from there onto my waterfalls. So I switched out my two pumps to 2 Lagunas after taking Haro's great advice and I loved their performance and energy savings. Then I ran 1 1/2" flex pvc pipe from them to the falls. On the way part splits to run some water over rocks in the pond by the corner of the deck, some splits off into a mini bog I made, another splits off into a trickle filter I put in, and then the rest heads to the falls. The water running over the rocks is 3/4-1" with a valve to limit the flow, the bog gets 1 1/2" pipe with a valve, and the trickle filter is 3/4" with a valve. This is all powered with a 2400 gph laguna, I got the 4200 gph to run the stream. Both combined use about the same electricity as my old Smartpond 5100 gph I used on the stream. Series of pics to follow, hopefully some each day. Oh and for those wondering, this winter has put us back into a solid zone 4a with record days with below zero temps, its kinda sad when you get used to walking out in single to negative digits and it feels normal, but warmer weather is on the horizen.
