It looks like I'm in this for the long haul. Lately I've taken a short break, because I had to work at my bread-winnin' job. But it's been good for me because I'm nearly exhausted and that puts me in a frame of mind to "just finish it", i.e. settle for less that I really want. Gad I'm tired of digging--and the deeper I go the harder it is to get the dirt up and out. The guy who was going to help me hasn't called. I checked with day labor outfits, but they want $20/per person per hour. I'm not sure how much I need them and hate to pay so much when I can do it myself, just way slower.
The fish seem pretty happy; No illnesses, no erratic behaviors or signs of problems, water's checkin out good, 10-15% water changes once a week. So, even though my preference is to get them back into the pond post haste, I've got a few things to think through first. And, I need some ideas/advice/suggestions please.
1st--fish motion/habitat. before i had a waterfall at one end and a skimmer at the other with a sloping bottom toward the skimmer. Still have that in the old hole, but the new excavation is a shelf about 1.5-2 ft above the other hole bottom. It has a steep wall. I'm thinking either of going ahead and excavating all of it (oh, my, god. is he crazy) or at least creating a sloping edge at either end so the fish can swim up and around on the ledge without having to change "altitude". smooth transition from bottom at either end up onto the ledge. is that dumb?
2nd-flow. do i need to figure a way to keep the water on the ledge moving somehow. the plan is for that ledge area to be for lillies and other plants so I plan to direct the waterfall toward the old pond to minimize surface water movement. so maybe I could put the outflow from the second pump (going through the bead filter) under the surface and against the wall of the ledge to encourage flow in the same basic direction as the waterfall, overall counter clockwise toward the skimmer.
3rd-enhance aquafalls filtration. The bead filter i have is for a 2000 gallon pond. the aquafalls filter is supposed to handle up to 6,000 gallons which i may approximate if i excavate the ledge. I'd like to enhance the fines filtration of the aquafalls. what do you folks think of putting a few cubic feet of the plastic type biomedia in the bottom? then, what'd I do is make a 2 in. pipe to come off the bulkhead and run across the bottom of the filter box. cap the end and drill multiple large holes in it to distribute the water rather than have it rush out of one orifice. my thought is the fines will have to work their way up through the biomedia before they hit any of the matting. then the filterfalls comes with two bulkheads, so the other will be setup as a backflush. do you think this would help with fines? I can't really afford a bigger bead filter right now.
well, that's it for now. attached are a few pictures, one at night. I got bored and couldn't sleep.
