Ok, so that was last summer...What's up for this summer?!
On another note: You've done a great job there, something to really be proud of.
How are the filters working out? Would you change anything with them?
The settling tank is a grand idea, any problems with algae in it?
I didn't notice any heating, how did the fish over-winter?

This summer will be fine tuning, mostly appearance, and well enjoying it.
I'm very proud how it turned, looking back........I should have had my neighbor come over with a bigger machine to take that tree down so I could have gone bigger!!!!
As for the filters, omg I would never give them up! The settlement tank is just that, heavier solids fall to the bottom of the tank. It's big enough to allow for several minutes of dwell time. I have a knife valve with a 4 foot handle at the bottom of the tank which has a 90 degree fitting on it to suck the bottom. It would be better if the bottom of the tank was a cone. This way everything exits. I currently use a broom to sweep to outlet and then open the valve.
As for the S&G filters these really polish the water and do a ton of bio. It consists of a bottom drain, a quick flush a every few days, all it takes is seconds. As soon as I open the 1 1/2 knife I close it. It has 5in 3/4 stone, 15 inches of 3/8 pea gravel and a 100 lb bag of #12 sand. Every 7 to 10 days I use a shop vac to blow air down the center pipe for 10 seconds to loosen the crud then open the valves at the top to flush the crud out. Maintenance wise once a week 10 minutes of my time. The only time consuming part is topping off the pond. I'll blow through a few hundred gallons of water.
This year I plan to either making a floating micro screen 500 micron for the settlement tank or a prefilter. I believe this would require less maintence on the S&G.
As for algae I have a ton of string algae on the pond walls. Maybe 3/4in to 1in long. The water has a greenish tint to it but if I fill a water bottle its crystal clear and partical free. I have no intention to get rid of the coat on the walls, the fish love it = no UV.
As for a heater, I'm either at or below frost depth. I leave an air pump running all winter to keep a hole in the ice. So far it hasn't been a problem. I'm in NJ so it does get pretty cold.
Projects this spring.
rotating micro screen
Locating 2 more 275 gal tanks or several 55 drums to store waste water from the S&G flush.
If I'm up for it, run some plumbing under ground to water the lawn, garden, plants with some fish fertilizer(waste water) I blow through a lot of water, watering the plants.
